Cross-Listing and Corporate Green Innovation: Evidence from Chinese AH Cross-Listed Firms

Abstract

The capital market is important to promoting the comprehensive green transformation of social development and facilitating the flow of social resources toward green innovation and low-carbon technologies. Mainland Chinese enterprises cross-listed in the Hong Kong stock market (AH cross-listed enterprises) provide a good experimental object for investigating the role of capital-market integration in promoting corporate green innovation behavior. This paper investigates the impact of Chinese AH cross-listing on corporate green innovation. Using the entropy balancing matching and difference-in-differences model (EB-DID model), we empirically analyze a sample of 13,538 valid firm-year observations (including 1206 AH-share ones) from Chinese listed firms between 2005 and 2023. Our research findings show that AH cross-listing promotes Chinese firms’ green innovation. Moreover, this effect is heterogeneous among firms with different financial constraint levels, external finance dependence, internal control quality, and audit quality. Finally, AH cross-listing spurs corporate green innovation by reducing equity capital costs and optimizing information disclosure quality. Our results are robust to alternative measurements of green innovation, alternative matching methods, alternative regression models, and various controls for endogeneity issues. The study reveals a new determinant of corporate green innovation and expands the boundaries of cross-listing’s microeconomic consequences.
