近年来，因公司经营暴雷而使得董事高管承担巨额赔偿的事件频频发生，购买董事高管责任保险成为越来越多中国企业的选择。通过收集我国A股上市公司2016—2020年的数据，实证探究董事高管责任保险对企业社会责任的影响，并深入分析其作用机制。研究结果表明，董事高管责任保险与企业社会责任履行正相关，内部控制在董事高管责任保险与企业社会责任之间起部分中介作用。进一步分析发现，经济政策不确定性负向调节董事高管责任保险与企业社会责任之间的关系；相较于非国有企业，董事高管责任保险与企业社会责任之间的关系在国有企业中更加显著。以上结论为完善我国董事高管责任保险制度，促进企业社会责任履行，提供了一定的经验证据。

In recent years, there have been frequent incidents that directors and senior executives have to bear huge compensation due to operation of their company. Therefore, purchasing directors' and officers' liability insurance has become the choice of more and more Chinese enterprises. By collecting the data of A-share listed companies from 2016 to 2020 in China, this paper empirically explores the impact of directors' and officers' liability insurance on corporate social responsibility and deeply analyzes its mechanism. The results show that directors' and officers' liability insurance is positively correlated with CSR performance, and internal control plays a partial intermediary role between directors' and officers' liability insurance and CSR. Further analysis shows that economic policy uncertainty negatively moderates the relationship between directors' and officers' liability insurance and CSR. Compared with non-state-owned enterprises, the relationship between directors' and officers' liability insurance and CSR is more significant in state-owned enterprises. The above conclusions provide some empirical evidence for improving our directors' and officers' liability insurance system and promoting the fulfillment of CSR.
