摘要: 结合财务困境的特殊背景,从CEO的角度探讨2007—2020年我国财务困境公司CEO变更对股价崩盘风险的影响。研究发现,财务困境公司的CEO变更与股价崩盘风险之间呈显著负相关关系。将CEO变更分为正常变更和非正常变更后发现,这种负相关关系在非正常变更的情况下更为显著。机制检验显示,CEO变更能够降低财务困境公司的融资约束和代理成本,进而作用于股价崩盘风险。进一步分析发现,CEO变更和非正常变更对股价崩盘风险的降低效应仅在非国有公司、股权制衡度较高以及外部审计质量较低的情况下存在,而正常变更的降低效应却在国有公司更加显著。

Abstract: Drawing on a sample of financially distressed listed companies in China spanning the period from 2007 to 2020, this study investigates the influence and underlying mechanism of CEO turnover on stock price crash risk. The findings indicate a noteworthy negative association between CEO turnover and stock price crash risk. After categorizing CEO changes into normal and abnormal changes, the study finds the negative correlation is more pronounced in the context of abnormal changes. Additionally, it is found in the mechanism test that CEO change can reduce the financing constraints and agency costs of distressed companies, and then reduce the company's stock price crash risk. Further analysis reveals that the reduction effect of CEO change on the stock price crash risk of financially distressed companies only exists in the case of non-state-owned enterprises, high degree of equity checks and balances, and low external audit quality. Notably, the normal turnover of CEOs in state-owned firms exhibits a more pronounced reduction effect on share price crash risk.
