监管政策、审计师变更与后任审计师谨慎性

本文以我国2001～2002年出台的相关审计监管政策为例,讨论审计监管对审计师变更和后任审计师谨慎性的影响。由于证监会2001年发布的《公开发行证券的公司信息披露编报规则第14号—非标准无保留审计意见及其涉及事项的处理》(以下简称14号文)增强了非标审计意见之于上市公司的不利后果,因此可能推动了机会主义审计师变更的增加。我们发现,在14号文出台后,前期非标审计意见同审计师变更的正相关关系变得更为紧密,且大所向小所的审计师变更频率显著上升。但是,没有证据表明,相比于未变更公司而言,变更公司的后续审计意见改善程度更高。并且,在2000～2002年,后任审计师针对变更公司的谨慎性有逐渐增强的趋势,这意味着2002年中注协关于审计师变更的监管政策可能发挥了一定的积极作用。
