Carbon emissions trading and corporate green investment: The perspective of external pressure and internal incentive
基于2009-2019年中国重污染行业上市公司数据，采用双重差分模型发现碳排放交易显著促进企业绿色投资，且外部压力与内部激励起调节作用。
Abstract The carbon emissions trading scheme (CETS) is an important institutional innovation that internalizes external costs caused by corporate carbon emissions and promotes firms to engage in green development. Based on a 2009–2019 sample of Chinese enterprises of heavily polluting industries listed on the Shanghai Stock Exchange (SSE) and Shenzhen Stock Exchange (SZSE), this paper employs the difference‐in‐differences model to examine the effect of CETS on corporate green investment and discuss the moderating effects of external pressure and internal incentive. We find that the implementation of CETS significantly promotes corporate green investment, and this finding still holds after a series of robustness tests such as Propensity Score Matching‐Difference in Differences (PSM‐DID) method and alternative measure of green investment. The heterogeneity analysis indicates that the positive effect of CETS is stronger in large‐scale enterprises, state‐owned firms, and companies located in regions with strict environmental regulation. In addition, less local government intervention and more internal executive compensation incentive significantly enhance the positive impact of CETS on corporate green investment.
