Empirical Research on the Impact of Ownership Structure and Management Behavior on the Environmental Disclosure:Evidence from Heavy Polluting Industries Listed in Shanghai Stock Exchange

企业环境信息披露水平与管理层行为有着密切关联,而股权结构又影响着管理层的行为决策。在当前管理层存在选择性披露行为的背景下,股权结构是否有助于遏制管理层的这种行为,进而提高我国企业的环境信息披露水平呢?本文以2007-2010年沪市A股重污染行业平均资产排名前20%的上市公司为研究对象,在委托代理理论和利益相关者理论基础上,实证检验了股权结构、管理层行为对环境信息披露选择的影响。研究结果表明,控股股东、制衡股东和政府部门对管理层的监管能有效引导管理层积极披露环境信息;管理层持股也有利于企业环境信息披露水平的提高。
