We examine the influence of political connections on firms' environmental performance within the setting of China's Regulation 18, which prohibits government officials from taking business positions. Firms that lost political connections due to Regulation 18 experienced increases in environmental performance. This improvement is mainly driven by the tunneling channel rather than the sheltering channel. Specifically, we decompose the environmental ratings into strengths and concerns, and find the effect is stronger on strengths. The environmental improvements are more pronounced for firms with a higher degree of tunneling, and are value-enhancing. Our findings suggest that political connections impede firms' environmental performance and generate negative externality to the environment.

Abstract By examining required rates of return, we study how shareholders perceive stronger stakeholder orientation arising under the adoption of constituency statutes. Constituency statutes decrease (increase) the cost of equity for firms operating in high- (low-) competition industries. For firms in high-competition industries, constituency statutes increase future cash flows and performance resilience to negative industry downturns, suggesting that constituency statutes facilitate CSR activities for product differentiation in competitive industries. In contrast, for firms in low-competition industries, constituency statutes reduce future cash flows and increase tail risks, suggesting that constituency statutes shield managerial agency problems from discipline.
