Carbon policy risk and corporate capital structure decision

This study examines the relationship between carbon policy risk and corporate capital structure in China. Using a sample of A-share listed firms from 1997 to 2018, we find that carbon policy risk reduces firms' financial leverage. The result is robust to the introduction of difference-in-differences tests, instrumental variable regression, and a placebo test used to address endogeneity, as well as to other tests of alternative measures. This negative relationship is more pronounced for non-state-owned enterprises, firms with low institutional investor ownership, firms with poor corporate social responsibility performance, firms belonging to competitive or carbon-sensitive industries, and firms located in provincial cities. Financing constraints, bankruptcy risk, and government power are potential mechanisms underlying this observation. Our findings provide practical sug-gestions through which firms can address carbon policy risk and provide guidance to governments and regulators for the further implementation of environmental policies.
