审计投入的产出效应

The Input-Output Effect of Audit Services

本文运用我国上市公司数据,研究了审计投入的产出效应问题。研究发现,审计投入与审计质量和审计收费都存在正相关关系,表明审计投入的增加能够提高审计质量,也能够带来审计费用的提高。进一步研究发现,审计投入对审计质量的影响程度在不同会计师事务所之间不存在显著的差异,但审计投入增加所带来的审计收费的提升效应,在国际"四大"和国内"十大"会计师事务所比在国内小所更明显。同时,审计投入的产出效应在不同股权性质及不同规模的公司中也存在差异。本文首次为审计投入与产出的关系问题提供直接的证据,同时也表明已有文献将审计费用作为审计投入的替代变量可能不是一个合适的方法(Gong等,2016)。本文的研究结论对于审计市场效率提升具有重要的启示作用。

Based on a sample of Chinese listed firms,this paper examines the input-output effect of audit services.Results show that the input of audit services is positively related with audit quality and audit fees.Further studies show that there is no difference in the relations between the input of audit services and audit quality among audit firms,but the increase in audit fees resulted from increased audit service inputs is more prominent in interna-tional Big 4 and Chinese domestic Big 10 audit firms.Furthermore,the input-output effect of audit services varies between state-owned firms and non-state-owned firms as well as among firms of different sizes.To the best of our knowledge,this is the first paper that directly examines the input-output effect of audit services.This paper also shows that using total audit fees as proxies for audit inputs is not appropriate（Gong et al.,2016）.The conclu-sion of this paper can be helpful for enhancing audit market efficiency.
