选择2008—2016年沪深A股上市公司数据作为研究样本,检验了盈余管理、战略性捐赠与公司股价波动三者之间的关系,结果表明:战略性捐赠削弱了公司股价波动;盈余管理增强了战略性捐赠削弱公司股价波动的功效;无论是国有企业还是非国有企业,战略性捐赠均削弱了公司股价波动,且非国有企业盈余管理在增强战略性捐赠削弱公司股价波动的功效方面更强.通过研究验证了"好"的盈余管理可以增强战略性捐赠削弱公司股价波动的功效,是企业谋求长效发展的治理机制,可以保护利益相关者多方权益,而非是单纯的管理层寻求私人利益的工具.%Taking the data of listed companies in A-share market from 2008 to 2016 as a sample,this paper tries to examine the relationship among earnings management,strategic donation and stock price volatility.
