| 摘 要： | 影响股价特质波动的因素是当前的热点研究问题。本文认为CEO权力通过降低公司风险承担水平、弱化公司治理机制有效性两条途径降低股价特质波动。为验证该基本假设,本文以2011~2017年中国A 股 上市公司为样本进行实证检验,发现在控制相关影响因素后,CEO权力对股价特质波动呈现出显著的负向影响,在非国有上市公司和小型企业中,这种关系更加显著。本研究丰富了有关CEO权力经济后果及股价特质波动影响因素的研究,对CEO权力的合理配置和公司风险管理均具有一定启示。

| Abstract: | At present, the factors affecting heterogeneity volatility of stock price are the hot research issues. This paper argues that CEO power may reduce the heterogeneity volatility of stock price by reducing the level of corporate risk taking and weakening the effectiveness of corporate governance mechanism. In order to verify this basic hypothesis, this paper takes Chinese A-share listed companies from 2011 to 2017 as samples for empirical analysis. After controlling relevant influencing factors,we finds that CEO power still has a significant negative correlation with heterogeneity volatility of stock price.The relationship is even more pronounced among non-state-owned listed companies and small scale companies. This study enriches the research on the economic consequences of CEO power and thefactors influencing heterogeneity volatility of stock price, and has certain enlightenment significance for the reasonable allocation of CEO power and corporate risk management. |
