客户和审计师不匹配关系与会计稳健性

以2007〜2018年我国沪深A股上市公司为研究样本,本研究考察了客户和审计师不匹配关系对公司会计稳健性的影响,并基于内部控制质量与机构投资者持股从内外部治理视角揭示其作用机理。研究发现,客户和审计师不匹配关系对公司会计稳健性的影响存在显著差异,向上不匹配有助于提升公司会计稳健性,而向下不匹配则会降低公司会计稳健性。这一正向(负向)影响随着公司内外部治理环境的改善有所削弱。通过中介效应检验发现,向下不匹配关系对会计稳健性的负面影响在一定程度上是通过审计监督弱化这一作用路径实现的,但向上不匹配关系的中介效应没有得到直接证据支持。本研究丰富了客户和审计师聘用关系经济后果的相关文献,有助于投资者从公司选聘会计师事务所的决策中甄别公司会计信息质量,对客户与会计师事务所之间聘用关系的良性发展有一定的启示。

Client-auditor Mismatches and Accounting Conservatism

Using A-share listed companies from 2007 to 2018 as samples,this paper finds that there are significant differences in the impacts of different types of client-auditor mismatches on accounting conservatism.To be specific,client-auditor upward mismatches help to improve corporate accounting conservatism,while clientauditor downward mismatches reduce corporate accounting conservatism.With the improvement of internal and external corporate governance environment,the positive(negative)impact of client-auditor upward(downward)mismatches on accounting conservatism will be alleviated.Further study shows that client-auditor downward mismatches reduce corporate accounting conservatism through the reduction of audit quality,but there is no significant intermediary effect in client-auditor upward mismatches.This paper enriches relevant literature on the economic consequences of client-auditor employment relationship,and is helpful for investors to discriminate between the quality of enterprise accounting information and the decision making of hiring accounting firms.Besides,it also provides useful insights for accounting firms and enterprises to promote the sound development of their employment relationship.
