Abstract
Extreme weather events have increasingly imposed significant shocks on corporate operations and the financial system's stability. This study examines the impact of extreme weather on the stock price crash risk and its underlying mechanisms using a sample of A-share listed companies on the Shanghai and Shenzhen stock exchanges from 2010 to 2023. The results demonstrate that extreme weather significantly increases the stock price crash risk for listed companies. After addressing endogeneity issues and conducting a series of rigorous robustness tests, the core conclusions remain robust. Channel analyses reveal that extreme weather exacerbates stock price crash risk by deteriorating corporate fundamentals, reducing the quality of financial disclosures, and exacerbating information asymmetry. Heterogeneity analysis further indicates that the reinforcement effect is more pronounced among firms in the eastern region, firms with high-quality information disclosures, and non-state-owned enterprises. These findings contribute to the literature by identifying novel determinants of stock price crash risk and shedding light on the role of climate risk among investors.
