摘要
本文以2007—2020年审计师变更为样本,考察年后变更审计师对审计意见购买的影响。研究发现,年后变更审计师的公司,进行了更多审计意见购买。业务复杂度、公司治理机制以及审计收费是影响年后变更公司能否实现审计意见购买的关键因素。进一步研究发现,年后变更审计师的公司,审计质量更差,体现为更多的应计盈余管理及财务违规。短期内投资者对年后变更审计师行为呈现出非理性的过度乐观,但长期来看,年后变更审计师的公司伴随着长期的股东价值损耗。研究结论表明,日常监督和充足的审计时间对审计意见购买及审计质量具有重要影响,审计师变更时点是具有丰富信息含量的风险信号。
This paper examines the impact of later auditor switch on audit opinion purchase with a sample of auditor switch from 2007 to 2020,it is found that companies which switch auditors after the fiscal year make more audit opinion purchases.Business complexity,corporate governance mechanism and audit fees are the key factors that affect whether a company can purchase audit opinions after the fiscal year.Further research finds that those companies also have poorer audit quality,which is reflected in more earnings management and financial irregularities.Finally,in the short run,investors are irrationally over-optimistic about auditor switch after the fiscal year,but in the long run,companies with auditor switched after the fiscal year are accompanied by long-term shareholder value loss.These results show that daily supervision and sufficient audit time have a significant impact on the purchase of audit opinions and audit quality,and the timing of auditor switch is a risk signal with rich information content.
