    The impact of environmental regulations and industrial structure adjustment on energy consumption
    ZHANG Guo-xing, JIA Yu-qi, BAO Hai-xu, NIE Yan, HU Yi
    2025(9):1-12
    [Abstract] (126) [PDF 1.20 M] (113)
    Abstract:
    Effectively alleviating the problem of energy consumption has become a key measure in building a resource-conserving and environment-friendly society in China. How does environmental regulation affect energy consumption in China against the background of continuous adjustment and optimization of industrial structure? In order to answer this question, this paper applies the PCSE method to empirically analyze the direct and indirect effects of different environmental regulations on industrial energy consumption, using the panel data from 30 provinces and cities in China from 2006 to 2017. The results show that: 1) Environmental regulations significantly influence industrial energy consumption. Market incentive environmental regulation performs the best, followed by public supervision environmental regulation,while the impact of command-and-control environmental regulation is weaker; 2) The interaction terms between environmental regulation and industrial structure confirm the comprehensive effect of market incentive and public supervision environmental regulations on energy consumption. Environmental regulations from the government can guide the adjustment and optimization of industrial structure, thereby effectively reducing energy consumption; 3) The threshold regression model of the command-and-control environmental regulation and energy consumption verifies the nonlinear impact.The energy saving effect varies with the degree of environmental regulation. According to the research results, several policy suggestions are put forward, such as paying different attention to the process of carrying out environmental regulation, focusing on its guiding role in the optimization and adjustment of industrial structure, to provide instructive reference and guidance for effectively reducing energy consumption.

    2025(9):13-34
    [Abstract] (76) [PDF 1.29 M] (107)
    Abstract:
    Breaking down tax system barriers between industries is crucial for advancing tax cuts and fees to support the real economy. Using the micro-level data from the nationwide enterprise registration database (SAIC) for 2009-2015 , this study examines the impact of the business tax replaced with value added tax reform (VAT reform) on regional entrepreneurial activities. The findings indicate that the VAT reform significantly increased the level of regional entrepreneurship. Furthermore, implemented specifically in the service sector, the reform not only facilitated the establishment of production systems with specialization of production and optimized regional industrial structures, but also enabled cross-industry transmission of entrepreneurship-promoting effects through industrial input-output linkages, indirectly boosting the development in related downstream manufacturing sectors. Overall, during the VAT reform period, the government incurred an average tax reduction cost of approximately 550 000 Yuan per newly established enterprise. Additionally, every 100 000 Yuan in tax reduction costs enabled the channeling of about 10 000 Yuan into the real economy sector. This research provides a quantitative policy evaluation reference for enhancing tax policies aimed at supporting the development of the real economy in the future.

    Abstract:
    This paper examines the identification and estimation of partially linear quantile regression models in the presence of sample selection. To address the selection bias arising in quantile regression, we model the joint distribution of the unobserved disturbances in the outcome and selection equations-using, for instance, a copula specification-to obtain consistent estimates. We set out the assumptions required for identification and, building on the generalized method of moments for quantile regression, develop estimation procedures for both the quantile parameters (or functions) and the copula parameters. We establish the consistency and asymptotic normality of the proposed estimators. For inference, we implement a nonparametric bootstrap to compute standard errors and construct test statistics to assess the validity of the nonlinear specification. Using a control function framework, we further clarify the relationship between the endogenous linear quantile selection model and our proposed specification. Monte Carlo simulations indicate that the estimators perform well in finite samples. Finally, we apply the methodology to estimate the returns to female education, demonstrating the model’s practical relevance.

    [Abstract] (55) [PDF 1.59 M] (85)
    Abstract:
    As e-commerce applications evolve from breadth to depth, personalization has become an important direction for e-commerce service innovation. In order to accurately predict consumers’personalized demand, this paper proposes a personalized demand prediction method with a limited preference constraint by integrating information of product description texts and display images. Inspired by the hypothesis of limited attention, this paper models the limited personalized preference of consumers, and combines the image and text features to construct a Sparse Text-Image Linked Topic Model with a limited preference constraint. The model predicts the individual demands of consumers through group interest modeling, individual preference modeling, and purchase decision modeling. Experiments on the Amazon public data set show that the proposed model can effectively predict group interests and personalized preferences of consumers. The integration of text and image information improves the interpretability of personalized demand prediction.

    Abstract:
    Talent distribution within China exhibits significant regional disparities. Local governments have implemented favorable policies to gain an edge in the increasingly heated competition for talent. These pose new challenges for exploring the law of talent flows and promoting balanced regional economic development. This study focuses on college graduates in China and builds a dynamic multi-region model of migration to quantitatively analyze the impact of different individual characteristics (such as academic degree, school rank, and major) and economic factors (including real wage, migration cost, and amenity) on their job location decisions. Using data from a leading professional social network, we find that migration frictions fall with higher academic degrees and school rankings. Graduates with science degrees encounter lower migration frictions than those with engineering or arts and social science degrees. Estimated barriers to talent inflows gradually increase from the northwest to the southeast. Counterfactual analyses imply that a permanent wage increase in any province improves the welfare of graduates across all provinces. Western provinces need to offer higher wages than coastal provinces to attract an equivalent talent flow.

    [Abstract] (64) [PDF 1.15 M] (93)
    Abstract:
    As an important part of China’s green manufacturing systems, green factory certification is a vital tool to accelerate green transformation in the industries sector. Based on national-level data on green factory certification, this study systematically examines the impact mechanism and economic consequences of green factory certificationon firms’ environmental protection investment from the perspective of peer effects. The research reveals that green factory certification exhibits significant peer effects, wherein the environmental protection investment of non-certified firms is increased by the presence of green factory certified firms within the same region and industry. The conclusion remains valid after a series of robustness and endogeneity tests. Moreover, the peer effects of green factory certificationon is stronger in the sample of large-scale firms, non-state-owned firms, heavily polluting firms, and non-high-tech firms. Furthermore, the study indicates that, compared to governance-oriented environmental protection investment, the effects of green factory certification have a more pronounced promoting effect on prevention-based environmental protection investment. Finally, this study discovers new evidence that green factory certification can promote firms’green innovation performance and regional environmental performance through peer effects. This study provides empirical evidence assessing the effectiveness of green factory certification as a leading exemplar, and offers practical insights from the perspective of peer effects to encourage firms to achieve green transformation.
    The influence of word-of-mouth diversity of original movies on the box office of sequels: An empirical study based on the analysis of movie reviews

    [Abstract] (57) [PDF 1.21 M] (80)
    Abstract:
    Due to the risky nature of the movie market, production companies increasingly rely on sequel movies to generate box office revenues. Existing research has examined various driving factors behind the success of sequel movies. However, researchers have paid limited attention to the impact of the content and variation in reviews of the parent movies on the box office success of sequel movies.This paper conducts an empirical analysis based on data from 150 sequel movies released in China from 2014 to 2018. Using machine learning-based text analysis methods, we measure the diversity of reviews for the parent movies and find a significant positive effect of review diversity on the box office performance of sequel movies. Additionally, we verify the role of information richness as the underlying mechanism. Specifically, the more reviews a parent movie receives, the stronger the positive impact of review diversity on the box office performance of its sequel movies. The number of media reports and the duration of sequel movies in theaters negatively moderate the main effect. This study extends the research on the movie market and provides a new perspective for firms to consider word-of-mouth factors for marketing sequel movies, thus offering important managerial implications.
    The impact of manufacturer cost-reduction investment on bilateral encroachment
    WANG Qi-jun, NIE Jia-jia
    2025(9):119-130
    [Abstract] (54) [PDF 1.19 M] (93)
    Abstract:
    This paper considers a supply chain in which one manufacturer can encroach by selling directly and one retailer can encroach by developing a store brand, and investigates the impact of the manufacturer’s cost-reduction investment on bilateral encroachment. The bilateral encroachment game models both without investment and with manufacturer’s investment are established, and the equilibrium encroachment strategies of firms are obtained. The results show that under a certain condition, the manufacturer’s investment can prevent the occurrence of bilateral encroachment. On the one hand, the investment increases the retailer’s revenue from selling the manufacturer’s products in the traditional channel; on the other hand, it also enhances the competitiveness of the manufacturer’s products. Moreover, the higher the consumers’ valuation of the store brand, the more intense the competition between two brands. Therefore, when consumers highly value the store brand, it is more advantageous for the retailer to give up the store brand and focus on reselling the manufacturer’s products that have both product and cost advantages. Additionally, the manufacturer does not need to open direct channel to deal with the retailer’s encroachment under this situation.
    Research on supplier alliances considering quality improvement
    LI Ting-ting, CHEN Jun-lin
    2025(9):131-142
    [Abstract] (53) [PDF 1.12 M] (86)
    Abstract:
    This paper studies an assembly system consisting of multiple upstream complementary suppliers and a single downstream assembler, where quality improvements in the components made by the suppliers have positive externalities. Specifically, the demand of final products can be enhanced by improving the quality of components. The complementary component suppliers can freely form coalitions to determine their wholesale pricing and quality-improvement efforts. Based on the concept of Nash stability, this paper characterizes the stable coalition structure of suppliers and the equilibrium decisions of the assembly system, and further discusses the influence of positive externalities of supplier quality improvement on the system. The results show that a grand coalition forms when the overall quality improvement efficiency of suppliers is high; otherwise, the suppliers act independently. In addition, due to the positive externalities of supplier quality improvement, suppliers with low quality-improvement efficiency can benefit from free riding. Compared to suppliers with higher quality-improvement efficiency, they make less effort in quality improvement but obtain higher profits. Finally, the free-riding behavior of suppliers is illustrated through numerical examples.
    Analysis on the supply mode of autonomous mobility service in mixed traffic environment

    2025(9):143-156
    [Abstract] (38) [PDF 1.51 M] (77)
    Abstract:
    In the era of mixed transportation systems, where service-oriented autonomous vehicles (AV) coexist with human-driven regular vehicles (HV), urban transportation network flows will consist of “decentralized” decisions made by commuters who choose the HV mode, and “centralized” decisions made by AV mobility service operators who assign routes to travelers opting for their AV mobility services. This paper presents a hybrid behavior equilibrium model that integrates the combined decision-making processes of elastic demand, traveler service/mode selection, and route allocation/choice, which enriched the theories of mixed networks equilibrium in mixed traffic environment. Two numerical examples are used to verify the effectiveness of the model, revealing that the optimal supply mode for the AV service market is a joint effort between the government and private enterprises. More importantly, this market structure can simultaneously achieve optimal efficiency in the transportation system and minimal perceived unfairness for travelers. This study provides valuable insights into important management questions such as what role the government should play in the AV service market.

    2025(9):157-173
    [Abstract] (52) [PDF 1.33 M] (70)
    Abstract:
    The intensification of global climate change in recent years has attracted widespread attention.By introducing climate change attention into the consumption-based capital asset pricing model, this paper theoretically analyzes how investors’climate change attention affects the expected returns of individual stocks. It then empirically tests the model’s hypothesis and mechanisms in China’s A-share market by constructing climate change attention indicators based on Baidu Information and Baidu Index related to the keywords of climate change.The results show that: First, the Beta of climate change attention has a negative effect on the future excess returns for individual stocks; this effect is time-varying and more pronounced during periods of high climate change attention. Second, the negative effects are more significant for the stocks issued by enterprises with better environmental performance. Third, investors’risk hedging demand is an important mechanism through which climate change attention affects stock excess returns. This effect is mainly driven by changes in investors’expectations of corporate cash flows, ESG preferences, and institutional shareholding ratios.
    Effects of the public’s risk perception bias on stock market risk: An analysis based on a typical major public health emergency
    HE Hong-bo, GUO Rui-qi, CHEN Yi-qing, CHEN Shou, ZHANG Wei
    2025(9):174-190
    [Abstract] (78) [PDF 1.38 M] (86)
    Abstract:
    Against the background of a major public health emergency, this paper examines the impact of this event on stock market risk in China from the perspective of the public’s risk perception bias. This paper measures the public’s risk perception bias through the susceptible-infected-recovered (SIR) model and text analysis and examines the impact mechanism of risk perception bias on stock market risk at both the market and industry levels. The empirical results show that risk perception bias significantly exacerbates stock market risk at both the market and industry levels, and that the effect is particularly significant during the period with high event risk. Meanwhile, this paper finds that investor attention plays an important mediating role in the relationship between risk perception bias and stock market risk, while its mediating effect is significant only during the period with high event risk. Finally, the impact of risk perception bias on stock market risk, as well as the mediating role of investor attention, vary across different sectors. These findings suggest that the public’s subjective perception of event risk deviates from the objective event risk, and the resulting irrational investment exacerbates the instability of the financial market during major public health emergencies.

    Mode selection and pricing strategy of paid membership video platforms
    Jiang Zhongzhong12, Li Kunyang12, Zhang Yingxiang3, He Na12
    Available online:  March 15, 2023
    [Abstract] (4246)
    Abstract:
    With the development of online video industry, a new profit model (paid membership), and a new supply chain mode (account sharing mode) were emerged. However, the existing online video pricing theories and methods based on the traditional supply chain mode (buyout mode) are difficult to meet the needs of practical development. Therefore, we study the pricing strategies of paid membership video platforms under two different supply chain modes, and then analyze the impact of supply chain modes and video quality on the pricing, profit and demand of the paid membership video platform. The result shows that: the video platform will adopt “free to members”, “discount to members” and “symmetrical pricing” successively with the increase of video quality in the buyout mode, while only “discount to members” and “symmetrical pricing” will be adopted successively with the increase of video quality in the account sharing mode. Meanwhile, the selection strategy of the optimal supply chain mode is mainly determined by video quality. Further analysis indicates that the high copyright rate under the buyout mode has a negative impact on the development of the online video industry, and the account sharing mode can make up for the deficiency of the buyout mode. At the same time, the research shows that the paid membership video platform does not directly obtain VOD revenue from ordinary users, and its revenue structure is determined by the proportion of existing members. In addition, the results of extending the model to member-only videos prove the robustness of the main conclusions of the paper. The conclusion of the study can provide useful management implications for paid membership video platforms and online video industry.
    Research on the value co-creation incentive mechanism of platform ecosystem in the context of emerging field
    Wei Jiang, Yang Jia Ming, Yang Sheng Xi
    Available online:  July 06, 2023
    [Abstract] (2530)
    Abstract:
    The blurred boundaries, temporary absence of regulation, and dynamic changes in the roles and interactions of members in the emerging field have led to the difficulty for actors with complementary resources in the field to form a clear perception of the "advanced" value proposition of platform enterprises, challenging the original logic of value co-creation within the platform ecosystem based on the premise of the comprehensible value proposition. In this vein, how platform enterprises promote the value co-creation in the context of emerging field has become an important theme that needs to be clarified in practice and theoretical research. Through the comparative analysis of two case companies, i.e., Weiyi and Xinye, this paper identifies two major value co-creation dilemmas in the platform ecosystem in the emerging field context, namely "ambiguous co-creation goals" and "ambiguous co-creation modes", which impede the complementors ' initiative to co-creating value in the focal platform ecosystem. Based on this, we further refines the strategic paths for platform enterprises to stimulate value co-creation of complementors in this context - the "traction" model with the core of explaining value proposition and the "boost" model with the core of co-creating value proposition. The identity positioning of platform enterprises as "leader of the ecosystem" or "partner of other complementors" is the core motive of their strategic actions. Overall, the theoretical model of "co-creation dilemma—identity position—strategic actions" is built, which is the driving mechanism of value co-creation in the platform ecosystem. Based on the characteristics of the emerging field, this paper proposes a strategic path for platform enterprises to promote ecological value co-creation under the premise of participants within the ecosystem have ambiguous perceptions of platform value proposition, and contributes to the research on value co-creation in platform ecosystems.
    The “Fourth Statement” of enterprises driven by big data: Theoretical analysis, data realization, and research opportunities
    CHEN XINYUAN, HE XIANJIE, ZOU RUKANG, HAN SONGQIAO
    Available online:  June 20, 2023
    [Abstract] (1938)
    Abstract:
    An enterprise’s financial statements provide investors with highly verifiable and comparable information about its financial position, operating results, and cash flows, and this information plays an important role in company valuation, contract formation, and capital market supervision. The advent of big data, however, has presented many challenges for traditional financial statements in terms of integrity and timeliness due to strict reviews of information, requirements of accounting standards, and restrictions on the form and frequency of disclosure. Based on the valuation function and contract function of accounting information, this paper researches the elements and the methods of realization of the “Fourth Statement”. Then, this paper further proposes the potential application scenario of the “Fourth Statement” in company valuation, contract signing, and capital market supervision.
    Stock Market Asymmetric Information Would Have an Effect of Contributing to Stock Price Crash: From a New Perspective of Uncertainty
    MAO Jie, LIU Hongzhong
    Available online:  August 02, 2022
    [Abstract] (2878)
    Abstract:
    We build a market microstructure model within the framework of Rational Expectations Equilibrium and deliberately factor uncertainty into our model so as to study from the perspective of uncertainty whether and how stock market information asymmetry would contribute to stock crash. Our model demonstrates that market information asymmetry does contribute to stock crash, and that the greater the information asymmetry, the deeper stocks would plunge, the greater the uncertainty in the market, the greater the impact information asymmetry would have on stock crash. We then calculate the probability of informed trading of A equities listed on the Shanghai and Shenzhen stock markets according to the relevant tick data from 2010 to 2015 and use the calculated probability of informed trading as a measure of information asymmetry of the Shanghai and Shenzhen stock markets. And we conduct empirical tests according to the calculated probability of informed trading to find that there exists a significant positive correlation between market information asymmetry and stock crash, and usually the greater the market information asymmetry, the deeper stocks would plunge. In addition, we also formulate uncertainty indexes for A equities listed on the Shanghai and Shenzhen stock markets, using the uncertainty indexes for measuring stock market uncertainty, and in the light of the uncertainty indexes we discover that market uncertainty tends to increase the impact information asymmetry would have on stock crash, i.e. the greater the uncertainty in the market, the greater the impact information asymmetry would have on stock crash. Our findings do not only add to the existing knowledge about the causes of stock crash, but also sheds new light on how to prevent abnormal volatility on stock markets.
    Do convex incentives boost asset prices and volatility?: Based on the perspective of investors' heterogeneous beliefs
    Xu Si, Sheng Jiliang
    Available online:  August 02, 2022
    [Abstract] (1274)
    Abstract:
    This paper analyzes the impact of convex incentives in delegated portfolio management to prices and volatility of the risky assets by using a theoretical model in continuous-time financial framework. First of all, we establish a multiple-stock dynamic equilibrium pricing model in which the institutional and retail investors have heterogeneous beliefs, and the institutional investors facing convex incentives which are associated with a benchmark portfolio's performance. Secondly, using the martingale method, we derive closed-form solutions for the risky asset’s equilibrium price and volatility. Finally, numerical results show that the stock in benchmark portfolio has higher price and volatility than the stock not in. The convex incentives to institutional investors can always boost the risky asset prices and the volatility of stock in benchmark portfolio. When institutional investors are more pessimistic than retail investors, the increase of convex incentives will reduce the volatility of the stock not in benchmark portfolio, and the increase of institutional market share will reduce the degree of bubble of stock not in benchmark portfolio.
    Born in Drought, Save against A Rainy Day: Does CEOs’ Childhood Drought Experience Improve Corporate Water Protection Performance?
    DU Xing-qiang, XIAO Liang, LIN Qiao
    Available online:  August 02, 2022
    [Abstract] (1933)
    Abstract:
    As an important and basic resource of social production and civil life, water plays a crucial role in constructing national ecological civilization and realizing healthy economic development. Based on the utilization efficiency of water resources and water pollution of Chinese listed firms during 2007-2017, this study examines the impact of the CEO's drought experience in the childhood on water protection performance. The findings show that the CEO's drought experience in the childhood (5-15 years old) is significantly positively associated with water protection performance, implying that the drought experience and risk awareness towards water imprint the CEO's behavior and improve water protection performance. In addition, CEOs' current perception of water shortage strengthens the positive effect of the CEO's drought experience in the childhood on water protection performance. Above results are still valid after a series of robustness tests and using the change model to address the potential endogeneity. Furthermore, results in additional tests show that the pollution control department has an intermediary effect between CEOs’ childhood drought experience and corporate water protection performance, the implementation of the Environmental Protection Law strengthens the positive effect of the CEO's drought experience in the childhood on water protection performance, and the positive relation between CEOs’ childhood drought experience and corporate water protection performance is more pronounced for firms in manufacturing and polluting industries.
    Market Sentiment and Fund Investment Strategy: Catering or Contrarian
    WANG JIAN, Yi Shangkun, Jiang Zhongzhong, Qin Xuwei
    Available online:  August 02, 2022
    [Abstract] (2251)
    Abstract:
    The investment strategy of mutual funds is the focus of common concern among academia, regulators and market participants. Based on the behavioral asset pricing theory, this paper quantifies fund investment strategies as the market sentiment sensitivity of portfolio returns and it is classified as sentiment catering strategy and contrarian strategy according to market conditions for the first time at the micro-level. To explore the systematic influence of investment strategy selection on fund flow, risk and manager’s effort by theoretical models and empirical tests, and analyze the influence mechanism of fund performance from the perspective of behavioral principal-agent. The result shows that, funds are more attractive to investors, especially individual investors when adopting the sentiment catering strategy, however, it will cause hidden infringements on the interests of investors, which is manifested by increased risks and reduced returns of the fund in the future, and fund managers achieve higher returns without having to pay more efforts. Further analysis shows that the passive laissez-faire behavior of fund managers only to please investors is an important reason for their poor performance; when the fund adopts the contrarian strategy, the effects are completely opposite. This study provides new approaches and enlightenment for the investment practice of small- and medium-sized, fund governance and supervision, and the explanation of fund market anomalies.
    SOEs Reform, Optimization of State-Owned Capital and Value Creation: Evidence from M&As of Chinese Central SOEs
    zhangchenyu, maoxinshu, maoju
    Available online:  August 02, 2022
    [Abstract] (1602)
    Abstract:
    This paper examines the effectiveness of the optimization and adjustment of state-owned capital layout from the perspective of value creation using the setting of Chinese central state-owned enterprises (CSOEs) M&As. The results show that the optimization and adjustment of state-owned capital layout has the effect of value creation, which can improve the efficiency of state-owned capital, but this effect only exists after the reform of the Third Plenary Session of the 18th CPC Central Committee. Further research shows that the value creation effect of state-owned capital layout optimization is heterogeneous. Compared with the CSOEs of specific functional and public service, the value creation effect of state-owned capital layout optimization is more significant in the commercial CSOEs, and the value creation effect of CSOEs through professional integration and holding merger is more significant. The study also confirm that the optimization of state-owned capital layout reduces the competition among CSOEs, and achieves the advantage of resource integration. Overall, this paper provides a new perspective for understanding the optimization of state-owned capital distribution, which has important practical guiding value for SASAC to promote the strategic reorganization of state-owned capital at microcosmic level and achieve the goal of state-owned economy.
    China’s Banking Systemic Risk under the Shock of Cross-border Lending
    Fang yi, Jing Zhongbo, Zeng Yanqi
    Available online:  August 02, 2022
    [Abstract] (1298)
    Abstract:
    Based on the improved Greenwood et al. (2015) model, this paper studies China’s banking systemic risk caused by cross-border lending. The results show that: (1) Under the impact of cross-border lending, the systemic risk is mainly determined by the asset side’s shock, and China’s banking systemic risk has four stage characteristics. (2) Systemic risk is affected by risk exposure, institutional asset size, leverage and indirect correlation, and these factors play different roles in different shocks and different stages. As an external shock, the risk exposure is less important than the internal characteristic factors such as the scale of institutional assets and indirect correlation. (3) The increase of systemic risk caused by cross-border lending can lead to adverse changes of macroeconomic variables in the future, and the systemic risk’s index is effective.
    Bank income tax and the deposit insurance price
    Ming Lei, Tang Hui, Yang Shenggang, Huang Yuanbiao
    Available online:  June 25, 2022
    [Abstract] (1053)
    Abstract:
    In the context of continuous economic downturn, China has launched a fiscal policy of tax and fee reduction in recent years. This paper studies the pricing problem of deposit insurance considering bank income tax and obtains the explicit solution of deposit insurance price. We also test the mechanism of bank income tax affecting deposit insurance price. It clearly shows that the premium per unit deposit decreases with the decrease of income tax rate, which proves the positive effect of tax and fee reduction policy on banks. The empirical results show that the increase of bank income tax rate will increase the deposit insurance rate by increasing the risk-taking level of the bank. The study in this paper provides theoretical basis and practical reference for further promoting the implementation of tax and fee reduction policies in the commercial bank system in the future.
    Asymmetric Time-Varying Effects of zone transfer Monetary Policy on consumer Prices: A Study based on Pigou Effect and Overadjustment Theory
    HuaYufei, lujin, wangqiusu
    Available online:  June 25, 2022
    [Abstract] (877)
    Abstract:
    Based on the theory of price overadjustment and Pigou wealth effect, this paper first analyzes the dynamic mechanism of monetary policy on CPI from the theoretical level. It is found that the increase of money supply will not only directly increase CPI, but also indirectly affect CPI through the overshoot effect of asset prices. Secondly, markov zone transfer model is further introduced to analyze the zone system of monetary policy. Finally, TVP-SV-VAR model and NARDL model are used to measure the dynamic influence relationship of monetary policy on asset price and CPI from the perspective of time variation and asymmetry. The results show that: first, monetary policy has obvious characteristics of two zones of expansion and contraction. Second, in the short run, monetary policy has an overshoot effect on asset prices compared with CPI, while in the long run, monetary policy indirectly affects CPI through the Pigou vian intermediary effect of asset prices. Thirdly, monetary policy has asymmetric effects on both asset prices and CPI. The effect of expansionary monetary policy is smaller than that of contractionary monetary policy. Meanwhile, asset prices also have asymmetric effects on CPI, and the "loss aversion" effect is obvious.

    Available online:  June 25, 2022
    [Abstract] (1512)
    Abstract:
    The investor irrationality in China"s stock market has always been important in asset pricing. In order to test the influence of investor irrational, Using stock trading data from 1997 to 2018, this paper builds an irrational belief variable based on the heterogeneous belief variable, and empirically explores the influence on stock anomalies. The results show that irrational beliefs have negative predictive power for future returns. To test the variable to explain the anomalies returns ability, this paper builds a belief factor model including market factor (MKT), size factor (SMB) and belief factor(FMG). And we copy the 102 anomalies of market friction, momentum-reversed, value-growth, investment, profits and intangible assets. Finally, this paper uses the CAPM model, FF-5 model, CH-3 model and B-3 model and finds that belief factor model has relative advantage from the results of both adjust alpha and significance of GRS tests. This suggests that irrational belief may be the main factor of stock anomalies.

    We proposed a time-varying higher-order co-moment estimate based on a single factor time-varying semi-nonparametric (SF-TVSNP) model. The model specification, model estimation and model selection approaches are given in this paper. The single factor model can efficiently reduce “the curse of dimensionality” problem in the time-varying higher-order co-moments estimation, and the semi-parametric structure can improve the robustness of the SF-TVSNP model. The empirical studies show that the SF-TVSNP model can effectively capture the time-varying structure of higher-order co-moments of asset returns, and it is more suitable for the latent structure of asset returns. High-dimensional dynamic portfolio based on the SF-TVSNP model can generate higher and stable economic value, which is further confirmed by robust analysis.

    Abstract:
    The technical default of urban investment?bonds and the default of urban?investment companies' non-standard financing have broken the long-standing “belief” in the rigid payment of urban investment?bonds, and the credit risk has become the focus of attention. Under the background of the implementation of the urban agglomeration strategy in China, based on the gravitational network of production factors within the Yangtze River Delta Urban Agglomeration, this paper empirically analyzes the impact of urban agglomeration spatial spillover on the credit risk of urban investment bonds. The study finds that: 1) There is a spatial overflow of credit risk within the urban agglomeration, and the credit risk premiums of urban investment?bonds in different cities fluctuate in the same direction. 2) The financial development of other cities especially peripheral cities is positive externality, which can reduce the risk. 3) There may be negative externalities in the economic development of urban agglomerations especially the peripheral cities, which will increase the credit risk. It provides a theoretical and factual basis for local governments to make effective use of the development opportunities of urban agglomeration, reasonably formulate fiscal policies and prevent and control regional financial systemic risks.

    [Abstract] (7300) [PDF 388.70 K] (8780)
    Abstract:
    Two pillar policies constitute a crucial part of the post crisis financial stabilization framework. As regards ameliorating the two pillar regulatory framework and mitigating banking sector risks, it is crucial to examine the effect of two pillar policies on bank risk taking in a systematical way. Hence, this paper analyzes the transmission mechanism between the two pillar policies and bank risk taking from a micro perspective. Based on this, an empirical study is conducted using bank level panel data from 262 commercial banks in China from 2007 to 2020, to test the effects. The findings are as follows: Contractionary monetary policy and macro prudential regulation both exert a marginal reducing effect on bank risk taking, while loose monetary policy exerts a risk spillover effect on banks, which can be mitigated by macro prudential regulation. Mechanism analysis shows that macro prudential regulation mitigates the spillover effect of monetary policy by alleviating the negative impact of low interest rate monetary policy on bank charter value and by attenuating the procyclical adjustment of bank leverage, thereby performing a coordinated risk abating effect. In terms of cross sectional dimension, interbank connection exerts an asymmetric influence on the coordination effect of two pillar policies on bank risk taking. In a monetary easing environment, an increase in the interbank connection level weakens the mitigating effect of macro prudential regulation on the risk spillover generated by loose monetary policy. In a monetary tightening environment, an increase in interbank connection level worsens the weakening effect of macro prudential regulation on the risk reducing effect of contractionary monetary policy. Besides, two pillar policies generate a better coordinated risk abating effect on larger banks or those with a lower proportion of non interest rate revenue. In terms of the time dimension, interest rate marketization strengthens the coordinated risk abating effect of two pillar policies, while increased monetary policy uncertainty weakens that effect.

    Abstract:
    Since the multifractal detrended partial correlation analysis method (MF DPXA) cannot measure the asymmetric dependence relationship under different trends (upward and downward), this paper proposes the multifractal asymmetric detrended partial cross correlation analysis method (MF ADPXA). Furthermore, the paper proposes a removing factors time delayed detrended cross correlation analysis (ETD DCCA) to study the risk transmission direction between stock markets. Taking Shanghai Component Index, Shenzhen Component Index, and Hang Seng Index as research objects, this paper empirically analyzes the asymmetric cross correlation and risk transmission between pairwise stock markets after removing the common influencing factors. The results show that, after removing the influence of one stock market, the long memory cross correlation between the other two stock markets is weak. When the return trend is upward, the long memory cross correlation increases, and when the return trend is down, the cross correlation shows anti persistence. The degree of asymmetry is greater when the fluctuation is large. The local cross correlation between the pairwise stock markets shows a weakening trend over time. As the time lag increases, the anti persistent cross correlation between the two two stock markets is enhanced. The risk of the Shenzhen Component index is mainly transmitted to the Shanghai Component Index, and the risk of the Shanghai Component Index is mainly transmitted to the Hang Seng Index. The Hang Seng Index has a stronger impact on the Shenzhen Component Index. This study has implications for re understanding the intrinsic dependent structure and risk transmission of Shanghai, Shenzhen, and Hong Kong stock markets, cross market portfolio, and risk management.

    Abstract:
    Given the increasing presence of female directors in firms，the roles they play in leading firms’decision-making have attracted extensive attention． However，little is known about why firms choose to appoint female directors at boards． Based on the framework of awareness-motivation-capability( AMC) ，this paper employs fuzzy-set qualitative comparative analysis method． This research investigates the configuration effects of seven congruent factors，including industry female director ratio，female leader，diversification，gender equality culture，regional marketization，financial performance，as well as their causal complex mechanisms on the appointment of female directors． The results suggest that the driving mechanisms behind the presence of a high number of female directors can be categorized into four types: “pressure and atmosphere driver”，“pressure and capability driver”，“pressure and desirability driver”and“desirability and capability driver”． Further， female leaders and industry female director ratio are critical driving factors． There is an asymmetric causal relationship between the mechanisms of high-degree female directors and those of non-high-degree female directors．

    [Abstract] (1563) [PDF 1.05 M] (6393)
    Abstract:
    Listed companies’violations have been an important issue that attracts the attention of the capital market． While studying the causal relationship between single-dimensional variables and this issue is crucial，constructing an effective holistic prediction model is also of great significance． This paper constructs a prediction model of listed companies’violations based on important company characteristics and managerial individual characteristics from the perspective of internal governance． Using a sample of Chinese A-share listed companies from 2008 to 2019，this study introduces two machine learning algorithms，LightGBM and SHAP，to examine the predictive ability，importance ranking，and prediction mode of the two types of characteristics on violation behaviors． The results show that the model can predict corporate violations to a certain extent，and corporate characteristics have a greater impact on the prediction than managerial individual characteristics． Specifically，higher information transparency of listed companies，higher net profit margin of total assets，lower asset-liability ratio，higher managerial shareholding ratio，lower performance volatility，and higher analyst attention are associated with a lower tendency for the model to predict violations． In addition，the model predicts an increased tendency for violations when executives are young and when the chairman and CEO roles are combined． Moreover，most corporate characteristics and managerial individual characteristics exhibit a non-linear relationship in predicting corporate violations，which is consistent with the findings of traditional theoretical and empirical studies． Overall，our study enriches the research on the characteristics of corporate executives in China from a predictive perspective and provides empirical evidence for regulatory authorities and investors to improve supervision and investment efficiency and for companies to optimize internal governance mechanisms．

    Customer allowance for doubtful accounts and the duration of supply chain relationship
    黄金波，尤亦玲，李仲飞
    2024(3):91-111
    [Abstract] (17723) [PDF 454.74 K] (4596)
    Abstract:
    Supply chain stability is an important component of national economic security. As a common item in supply chain purchase and sale transactions, the allowance for doubtful accounts is particularly noteworthy for its potential impact on the duration of supply chain relationships. The paper examines the impact of customer allowance for doubtful accounts on the duration of supply chain relationships, using a research sample of A share listed companies on Shanghai and Shenzhen Stock Exchanges from 2008 to 2022. The study finds that customer allowance for doubtful accounts is significantly negatively related to the duration of the supply chain relationship. Mechanism tests indicate that customer allowance for doubtful accounts increases firms’finance, credit, and market risks through the supply chain risk contagion effect, prompting firms to interrupt current supply chain relationships due to risk aversion motivations. Further analysis shows that the negative impact of customer allowance for doubtful accounts is more significant in samples with lower prudence in allowance for doubtful accounts, higher downstream discourse power of suppliers, lower upstream discourse power of customers, and lower supply chain relationship survivability. Economic policy uncertainty exacerbates the negative impact of customer allowance for doubtful accounts on the duration of supply chain relationships, while a good business environment can weaken this adverse effect. The paper enriches the research related to the supply chain risk contagion effect and the duration of supply chain relationships from the perspective of customer allowance for doubtful accounts, and also has policy implications for enhancing supply chain resilience and risk resistance, as well as maintaining supply chain security and stability.
    How can government subsidies promote technological innovation of new energy enterprises?
    ZHANG Yue-jun, LIU Wen-li
    2025(2):1-14
    [Abstract] (14393) [PDF 1.17 M] (2379)
    Abstract:
    In order to stimulate the technological innovation of new energy enterprises, the Chinese government has issued a large number of relevant subsidy policies. However, the complex influence mechanism of government subsidies on technological innovation of new energy enterprises is still unclear, and the incentive effect has not yet reached a consensus. Therefore, this paper focuses on the data of China’s A-share listed new energy manufacturing enterprises from 2011 to 2020, and constructs a two-way fixed effect model of panel data to investigate the influence of government subsidies on technological innovation of new energy enterprises. The findings are as follows: 1) Government subsidies generally promote the technological innovation of new energy enterprises. In the sample interval, for every 1〖WTXT〗%〖WTBZ〗 increase in government subsidies, the patent applications of new energy enterprises increase by 0.82〖WTXT〗%〖WTBZ〗; 2) R&D investment and innovative human capital play a partial intermediary role in the process of government subsidies to promote technological innovation of new energy enterprises, while enterprise financialization plays a moderating effect which enhances the promoting role of government R&D subsidies to the technological innovation of new energy enterprises; 3) There are significant differences between R&D and non-R&D subsidies on technological innovation of new energy enterprises: for every 1〖WTXT〗%〖WTBZ〗 increase in R&D subsidies in the short term, the patent applications of new energy enterprises increase by 1.064〖WTXT〗%〖WTBZ〗, and the relationship between R&D subsidies and technological innovation of new energy enterprises shows an inverted U-shape in the long term; for every 1〖WTXT〗%〖WTBZ〗 increase in non-R&D subsidies, the patent applications of new energy enterprises increase by 0.61〖WTXT〗%〖WTBZ〗; 4) The promoting effect of government subsidies on technological innovation of new energy enterprises is significant in the areas with high intellectual property development level, but not in the areas with low intellectual property development level. These research results will provide powerful decision-making reference for the government to formulate new energy industry policies and new energy enterprises to make good use of government subsidies.

    [Abstract] (2360) [PDF 1.42 M] (2388)
    Abstract:
    The rapid development of artificial intelligence (AI) means that humans are no longer the only subject of knowledge generation, so how to achieve effective collaborative learning between humans and AI becomes a focal issue. In the practice of human AI synergy to achieve organizational learning, this paper explores the impact mechanism of adding AI on the existing organizational learning approach. Based on a multi subject modeling and simulation approach, the paper finds that: 1) When environmental dynamics are not taken into account, high learning ability AI has a substitution effect of on organizational members. On the one hand, the exploratory learning needs of organization members are weakened, and on the other hand, the exploitative learning of organization is replaced. 2) The degree of collaboration between human and AI has a nonlinear effect on organizational knowledge level. When the organization is dominated by exploitative learning, the growth rate of organizational knowledge will slow down gradually as the synergy degree increases. When the organization is based on exploratory learning, only a higher degree of collaboration can improve organizational knowledge. 3)In the scenarios of high uncertainty, high learning ability AI has a complementary effect with organization members. The improvement of the organization’s knowledge level depends on more exploratory learning by the organization members, and the new knowledge generated by the cooperation between the organization members and AI needs to be quickly transformed into the organization’s routine. This paper breaks through the implicit assumption that human is the only learner in an organization, and reveals the characteristics and rules of collaborative learning between human and AI in different scenarios based on simulation, which provides enlightenment for promoting the rational allocation of scarce resources and the improvement of organizational learning performance in the era of digital economy.
    Supply chain spillover effects of green technology innovations

    2025(1):77-99
    [Abstract] (2126) [PDF 1.27 M] (1885)
    Abstract:
    The supply chain is a core channel for inducing knowledge spillover effects among companies, but studies onthe micro-mechanism of knowledge spillover along supply chain of green technology innovations are scarce. From the perspective of supply chain relationship, this paper systematically examines the impact of manufacturing customer companies’ green technology innovations on supplier companies in both “quantity” and “quality” dimensions, and further reveals the chain reaction in supplier company performance. This study finds that customer companies’ green technology innovations help improve green innovations by supplier companies both qualitatively and quantitatively. The heterogeneity analysis shows that supply chain spillover effects of green technology innovations are more pronounced in case of higher customer concentration, non-state-owned enterprises, or southern regions. Further investigations reveal that customer companies’green technology innovations also have spillover effects on supplier companies’future economic and environmental performance. This paper sheds new light on the implicit contribution of supply chain spillover effects in green technology innovations amongst Chinese manufacturing companies, which has theoretical and practical significance for the transformation and upgrading of Chinese manufacturing industries and for smoothing the domestic circulation.
    Asset pricing research based on autoencoder machine learning: A financial big data analysis perspective of the Chinese stock market
    TANG Guo hao, ZHU Lin, LIAO Cun fei, JIANG Fu wei
    2024(9):82-97
    [Abstract] (2048) [PDF 1.25 M] (2522)
    Abstract:
    This paper predicts stock returns in the Chinese market by using an improved autoencoder machine learning approach and financial big data encompassing approximately one hundred firm characteristics. The findings demonstrate that the autoencoder factor can extract predictors from a large amount of information containing company characteristics to forecast returns and can achieve significant excess returns in the cross sections. Additionally, the analysis on the significance of factors reveals that the anomalies are time varying in the Chinese stock market. Additionally, the predictive efficiency of the autoencoder method correlates with macroeconomic conditions and economic policies. The autoencoder based long short portfolios can effectively mitigate market risk especially during substantial market bubbles and heightened speculative periods, demonstrating well resilience to the shifts of fiscal and monetary policy induced economic conditions.

    [Abstract] (1866) [PDF 2.06 M] (2061)
    Abstract:
    The essence of recommender systems is to model the implicit preferences in consumer behavior. The human behavior is inseparable from psychology, and there are rich internal motives behind the superficial behavior. However, the current studies mainly focus on the behavioral data modeling, rarely involving the internal psychological activities and the information processing process of decision-making. Therefore, this paper studied a new idea of recommender systems by introducing AIDMA decision model from the perspective of consumer decision journey. A new deep review-based recommender system is proposed, which applies the AIDMA decision journey into the deep learning framework. Experiments showed that the recommendation performance of the proposal is significantly better than the state-of-the-art methods. This paper follows the big data-driven research paradigm of “model driven+data-driven”, realizing in-depth methodological innovation with theoretical support.

    2024(3):15-38
    [Abstract] (1677) [PDF 1.33 M] (4182)
    Abstract:
    Based on mental accounting theory, this research explores the effect of windfall money on purchase intention for new products through six studies. The results show that consumers who receive unexpected windfall money are more willing to purchase new products than those who do not receive unexpected windfall money (Studies 1a, 1b, and 2). Moreover, perceived risk is the underlying mechanism (Studies 3a and 3b). Product involvement plays a moderating role: The effect of windfall money on purchase intention disappears for high involvement new products but persists for low involvement new products (Study 4). This research expands the research scope of windfall money, enriches the influencing factors of purchase intention for new products, and provides evidence for companies to present the discount information.

    [Abstract] (1472) [PDF 1.42 M] (3550)
    Abstract:
    With the emergence of new consumer behaviors and the continuous awakening of demand individuation on the service demand side, the innovation model of the service supply side needs to be reconstructed urgently. Deep digitalization represented by the Internet has become a new engine to bridge the “service divide”. This article focuses on the healthcare industry that is deeply integrated with the “Internet +” trend. It selects the service model cases of Xiamen “healthcare+Internet” and WeDoctor “Internet+healthcare”, and systematically explores the service reshaping mechanism that bridges the service divide based on digital empowerment. The study found that the service divide can be deconstructed into three aspects: information asymmetry, resource mismatch, and data islands. The process of service reshaping based on digital empowerment is the key path to bridging the service divide, which could be mainly manifested in the reshaping process of service design, service delivery and service interaction. The service reshaping mechanism of “healthcare+Internet” and “Internet+healthcare”follows the service digitization logic and digital servitization logic respectively. Specifically, the former focuses on service-dominant logic and the transformation of the service nature based on digital technology, while the latter focuses on the application and innovative diffusion of digital technology. The theoretical framework finally formed in this article can contribute to the theoretical gap caused by the existing literature on the path of bridging the service divide. The logic of service digitization and digital servitization, based on the service reshaping mechanism under digital empowerment, further deepens the exploration of the theoretical laws behind the deep integration of digital technology and service fields.

    [Abstract] (1411) [PDF 1.31 M] (1423)
    Abstract:
    Will the digital transformation of firms be affected by policy uncertainty? This paper investigates the mechanisms by which policy uncertainty affects corporate digital transformation behavior through a theoretical model. Based on this, this paper uses the data of China’s A-share listed companies to conduct an empirical study on the relationship between policy uncertainty measured by local government official changes and corporate digital transformation. The results show that the increase in policy uncertainty can significantly impede the process of digital transformation. In addition, the relationship between policy uncertainty and digital transformation is moderated by the professional background of officials and corporate financial constraints. This paper provides evidence for better driving the digital transformation of Chinese firms.

    2025(2):15-30
    [Abstract] (1386) [PDF 1.14 M] (1088)
    Abstract:
    Digital transformation has fundamentally reshaped the landscape of traditional industries, necessitating institutional entrepreneurship to overcome existing constraints. Despite its significance, the process of institutional entrepreneurship during digital transformation remains underexplored in current literature. This study leverages institutional entrepreneurship theory and enterprise survey data to investigate how digital leadership impacts digital transformation performance. Our findings reveal that digital leadership significantly enhances digital transformation outcomes by fostering institutional change activities. Furthermore, the capability for information search is found to positively moderate the relationship between digital leadership and institutional change activities. By integrating institutional entrepreneurship theory into the realm of digital transformation, this research broadens the theoretical framework and offers fresh insights. It also advances the application and development of institutional entrepreneurship theory within the context of digital transformation, providing valuable guidance for enterprises seeking to improve their digital transformation performance.
