Although substantial financial reforms have been implemented, asset-debt maturity mismatch performs an exacerbated trend. From the perspective of human capital in the financial sectors, this paper provides an explanation using the sensitivity of fixed-assets investment to short-term debt. Specifically, this paper utilizes the 2008 Chinese National Economic Census to construct city-level measure of financial sectors’ human capital, and then matches the data with Chinese Industrial Enterprises Database over 2011-2013. The results show that human capital in the financial sector strengthens the positive effect of short-term debt on fixed-assets investment, especially for firms facing greater information asymmetry. Further, high-educated workers flowing to the financial sectors enhance their market power on credit allocation, resulting in decreased debt maturity provided for firms. These findings demonstrate that increasing human capital in the financial sectors lead to more serious mismatch of asset and debt maturity, which is conducive to explaining why China’s nonfinancial firms are using more and more short-term debt to invest fixed-assets.
