审计风险联结是否影响关键审计事项披露行为?——基于“低质量审计传染”问题的情境研究

Does Audit Risk Link Affect the Disclosure Behavior of Key Audit Matters?-A situational study based on the"contagion effect of low-quality audit"

低质量审计传染对于审计师与上市公司具有负面影响。本文采取2016-2022年我国A股上市公司的数据,基于财务重述事件中错报年时,上市公司之间因相同签字审计师产生的审计师联结,将重述年时被联结公司受低质量审计传染的影响作为“审计风险联结”。本文发现,审计师显著倾向于提升关键审计事项披露以应对审计风险联结;异质性分析发现,财务重述事件受到监管部门披露、期间发生过审计师变更及审计师行业专长均能显著加强上述效应;拓展性研究发现,在审计风险联结情境下,关键审计事项披露能够显著提升审计质量。本文结论有助于认识声誉维护动机下低质量审计传染对于审计师行为的影响,并识别了关键审计事项披露在其中发挥的应对作用与治理效果。
