摘要: 控股股东股权质押是资本市场中常见的融资手段,其对上市公司股价崩盘风险的作用机制有待进一步探讨。基于控制权转移视角,本文以2009—2018年A股上市公司为研究样本,构建控股股东股权质押影响股价崩盘风险的模型,并引入真实盈余管理作为调节变量,探究控股股东股权质押对上市公司股价崩盘风险的影响路径。研究发现,控股股东股权质押与股价崩盘风险存在显著正相关关系,真实盈余管理在股权质押与股价崩盘风险之间存在显著的正向调节效应,且在控制权不发生转移的情况下,上述两种关系更加显著。进一步研究发现,上市公司的股权集中度和治理结构影响本文的研究机制,当控股股东的直接持股比例小于50%或该上市公司不存在董事长与总经理兼任时,股权质押、真实盈余管理与股价崩盘风险三者的影响路径更为显著。

Abstract: The controlling shareholder′s equity pledge is a common financing method in the capital market, and its effect mechanism on the stock price crash risk of listed companies needs to be further explored.From the perspective of control right transfer, this paper takes A-share listed companies from 2009 to 2018 as research sample, constructs the model of controlling shareholder′s equity pledge influencing stock price crash risk, and introduces real earnings management as the adjusting variable to explore the influence path of controlling shareholder′s equity pledge on stock price crash risk of listed companies.It is found that there is a significantly positive correlation between controlling shareholder′s equity pledge and stock price crash risk. Real earnings management has a significantly positive moderating effect on equity pledge and the stock price crash risk, and the above two relationships are more significant when the control right does not transfer.Further research finds that the ownership concentration and governance structure of listed companies affect research mechanism. When the direct shareholding ratio of controlling shareholders is less than 50% or there is no chairman and general manager in the listed company, the impact path of equity pledge, real earnings management and stock price crash risk is more significant.

Key words: controlling shareholder′s equity pledge, real earnings management, control right transfer, stock price crash risk
