摘要
在中外审计实务中审计师任期交错是一种普遍现象,已有研究主要从静态考察审计师任期长短对审计质量的影响,但从动态看任期交错很可能是影响审计质量的一个重要却被忽略的因素。基于审计师任期管制视角,考察审计师任期交错对审计质量是产生提升效应还是产生降低效应,从客户公司、审计师个体和事务所主体3个维度,考察任期交错效应发挥作用的约束机制。以2009年至2017年中国沪深A股非金融类上市公司作为研究样本,运用Stata 15.0进行多元回归分析,构建Heckman两阶段模型和DID模型缓解内生性问题,保障研究结果的稳健性。研究结果表明,(1)审计报告中两位签字审计师的任期交错能够提高审计独立性并提升审计质量,而且二者任期错开的年数越长,交错效应越强;区分审计师角色,无论项目负责人与项目合伙人的任期孰长孰短,任期交错的积极效应都显著存在。在考虑任期临界点和内生性问题等一系列稳健性检验后,结果仍成立。(2)进一步考察审计师任期交错效应的约束机制发现,任期交错效应在阅历丰富审计师组合、男性组合、异地审计和审计聘任初期阶段更明显,但被老客户审计中形成的超工具性关系显著弱化。然而,任期交错效应不受事务所类型或审计师教育背景等因素影响。基于审计师轮换制度背景,探讨审计师任期交错行为及其经济后果,拓展了审计质量的影响因素研究;从客户公司-审计师-事务所3个维度厘清了审计师任期交错效应的作用机理,引导事务所优化审计师资源配置,完善审计质量控制路径和机制。审计师任期交错这一新视角为研究任期管制问题提供了来自中国资本市场的证据。
The staggered auditor tenure can be regarded as a common phenomenon in domestic and foreign audit practices.In the existing literature,scholars mainly focused on the influence of auditor tenure on audit quality from the static point of view,while from the perspective of dynamic views,tenure interleaving can be deemed as an important factor affecting audit quality,but it can be easily neglected.From the perspective of auditor tenure control,this study examines whether the impact of the staggered auditor tenure on audit quality can be described as“promotion effect”or“reduction effect”.Then,in the three dimensions of client companies,auditor individual and audit firm,this study also examines the constraint mechanism of the staggered tenure effect.Taking Ashare non-financial listed companies in Shanghai and Shenzhen from 2009 to 2017 as the research sample,software stata15.0was therefore applied to not only carry out multiple regression analysis,but also construct Heckman double-staged model and DID model to alleviate endogenous problems and ensure the robustness of research conclusions.The results of this research can illustrate that:(1)the staggered tenure of two signing auditors in the audit report can indeed improve the audit independence and audit quality,and the longer the staggered years is,the stronger the staggered effect will be.At the same time,to distinguish the role of auditor,no matter how long the tenure of the project leader or the project partner can be,the positive effect of tenure interleaving can be deemed as significant.After considering a series of robust tests such as tenure critical point and endogeneity,the conclusion can be still valid and concrete.(2)This study make further study on the constraint mechanism of auditor tenure staggered effect,which shows that the staggered effect is more obvious in“experienced auditor combination”,“male combination”,“non-local audit”and“initial stage of audit engagement”to some extent;however,the super instrumental relationship formed
