Cost of debt financing, stock returns, and corporate strategic ESG disclosure: Evidence from China

Whether corporate strategic Environmental, Social, and Governance (ESG) disclosure can be effectively screened by external markets still needs more empirical support. Despite numerous studies confirming the positive impact of ESG, the issue of strategic ESG disclosure has yet to receive sufficient attention. This study examines the impact of ESG greenwashing on the cost of debt financing and stock returns using panel data of Chinese A‐share listed corporates from 2012 to 2021. The study finds that external markets fail to recognize ESG greenwashing in the short term, leading to a temporary reduction in the cost of debt financing and an increase in stock returns, but these effects are not lasting. Mechanism analysis shows that ESG greenwashing enhances corporate reputation and reduces the cost of debt financing through the reputation effect, stimulates investor sentiment, and improves stock returns through the sentiment effect. The study identifies management myopia, excessive power, financial distress, and information asymmetry as the main drivers. However, strong oversight by independent directors, involvement of Big Four audit firms, investor site visits, and high industry competition can mitigate these misleading effects. This research expands the understanding of the causes and economic consequences of corporate ESG greenwashing and provides empirical evidence for managing this phenomenon.
