As a new economic format，sharing economy has brought far-reaching impacts to market participants such as consumers，enterprises and platforms. Meanwhile，it has also brought several social problems. In the field of economics and management，quantitative research on sharing economy has grown rapidly，especially with regard to its external impacts. However，there is a lack of systematic and comprehensive analysis. This paper comprehensively classifies the existing literature of sharing economy into analytical and empirical work， and summarizes them from perspectives of consumers，enterprises/distributional channels，sharing platforms and the society，respectively. Further，the paper provides implications for domestic scholars to carry out relevant research as well as insights for enterprises，platforms and policy makers.
