市场在关注审计师的职业声誉吗?——基于“科龙电器事件”的经验与启示

Does the Market Care Auditors' Reputation?——Evidence and implications from the case of"KeLong Electric"

本文以我国资本市场上备受瞩目的"科龙电器事件"作为切入点,研究了我国的投资者是否关注审计师的职业声誉。研究结果显示,当审计师声誉受损时,市场会对其审计质量产生怀疑,并且通过股价机制体现出来。在本文研究的对德勤职业声誉造成严重影响的两个事件点,市场对经德勤和其他"四大"会计师事务所审计的上市公司都做出了负面的市场反应,且投资者对两者的反应程度并没有显著的差别。进一步的研究还发现,在声誉受损事件中,对于不同公司,投资者做出的负面市场反应并不相同,当公司存在盈余管理的可能性越犬,市场的负面反应也越强烈。
