关键审计事项应对与会计稳健性——基于实地走访程序的经验证据

Responses to KAMs and Accounting Conservatism: Empirical Evidence Based on Field Visiting Procedures

本文利用手工收集的A股上市公司2017年新式审计报告披露的关键审计事项数据,研究关键审计事项应对对客户会计稳健性的影响。我们创新地以能获得较可靠审计证据、成本较高的实地走访程序表征关键审计事项应对力度,同时采用应计现金流模型、Basu反盈余报酬模型和C-Score稳健性指数计量会计稳健性,发现关键审计事项应对力度提升了会计稳健性,在控制内生性后结论仍然成立。进一步研究表明关键审计事项应对在贷款银行监督力量较弱的企业、稳健性需求较大的民营企业里对会计稳健性起到显著提升作用。本文的贡献在于为审计质量研究开辟了新的思路,拓宽了会计稳健性影响因素的研究领域,证明了关键审计事项披露的信息价值。

Using the data of key audit matters(KAMs)disclosed in the new-style audit reports of A share listed companies in 2017 which were hand-collected,this paper studies the effect of the responses to KAMs on the clients5 accounting conservatism.We innovatively proxy the strength of the responses to KAMs with field visiting procedure which can obtain more reliable audit evidence and need higher cost,use ACF model,Basu model and C_Score conservatism index to measure accounting conservatism,and find that the strength of the response to KAMs improves accounting conservatism.The conclusions are still valid after controlling endogeneity.Further research shows that the responses to KAMs play a positive role on improving accounting conservatism in the enterprises with weaker supervision power of loan banks or private enterprises with greater demand for conservatism.The contributions of this paper lie in breaking a new path for the research of audit quality,extending therange of research on the influencing factors of accounting conservatism,and proving the informative value of the disclosure of KAMs.
