摘要:Environmental regulation is an institutional guarantee for achieving green and sustainable economic development, and the implementation effect of environmental regulation policies is a concern for all sectors of society. This paper empirically examines the impact of environmental regulation on firms’ environmental governance behavior using a double difference model with the help of a quasi-natural experiment, the new Environmental Protection Law, and analyzes the mediating effect of central environmental protection inspectors using data from listed companies in China from 2011 to 2020. It was found that environmental regulation significantly enhances firms’ motivation to participate in environmental governance and central environmental protection inspectors play a mediating role in the impact of environmental regulation on firms’ environmental governance behavior. Furthermore, heterogeneity analysis shows that the enhancement effect of environmental regulation on firms’ environmental governance behavior mainly exists in large-scale firms and nonstate enterprises.
