中文摘要：

以2008—2013年沪深两市自愿披露社会责任报告的A股上市公司为样本,引入CEO权力等情境因素,研究了社会责任信息自愿披露对会计盈余质量的影响。实证结果发现,在控制样本自选择问题后,社会责任信息自愿披露具有显著的盈余质量提升效应;进一步考虑CEO权力对企业自愿披露决策的影响后发现,企业社会责任信息自愿披露的盈余质量效应受到CEO权力大小的制约,当CEO权力较大时,自愿披露社会责任信息与会计盈余质量的正相关关系不再显著。研究结论表明,企业社会责任信息自愿披露在一定程度上改善了企业的信息环境,提升了会计盈余质量,但社会责任信息自愿披露的盈余质量效应呈现出异质性和情境依赖性的特征。
