摘　　要：为探究独立审计鉴证与证券交易所自律监管这两种公司外部治理机制的关系,本文以2017-2020年我国A股上市公司为样本,分析发现,关键审计事项的披露数量越多,年报被实施问询的概率越高。这两种公司外部治理机制的互补关系主要体现在非常规关键审计事项对交易所问询内容的影响上。进一步分析发现,在具有行业专长的审计师组和正向异常审计费用组,审计师披露的非常规关键审计事项更能为交易所监管提供风险提示线索;当被监管企业盈余管理程度较高时,非常规关键审计事项为交易所监管部门提供监管线索的作用更加明显。研究验证了审计师与交易所监管部门之间在信息披露监管上存在互补关系,两者在提高上市公司信息披露质量方面存在更大的协作空间。In order to explore the relationship between the two external governance mechanisms of companies,i.e. independent audit oversight and stock exchange self-regulation, this paper analyzes the impact of critical audit matters(CAMs) disclosures on the issuance of annual report comment letters, taking A-share listed companies from 2017 to 2020 as a sample. The results show that the CAMs disclosed by auditors can significantly increase the probability of comment letter filed on listed companies. The complementary relationship between the two is mainly reflected in the impact of unconventional CAMs on the content of comment letters. Moreover, when auditors have industry expertise or positive abnormal audit fees, the complementary relationship between the two is significantly enhanced;when the regulated enterprise has a high degree of earnings management, the role of unconventional CAMs in providing regulatory clues to exchange regulators is more obvious. The study verifies the complementary relationship between auditors and exchange regulators in information disclosure supervision,and there should be more room for the coordination between the two mechanisms in improving the quality of information disclosure of listed companies.
