Abstract: This paper examined whether and how institutional environment and media monitoring affect the auditing quality by selecting a sample listed companies in A stock market from 2008 to 2011, based on principal component analysis and Heckman sample selection model. It indicates that auditing quality can be high in better institutional environment area and media monitoring can improve it, especially negative media exposure can promote auditing quality improvement strongly. And media monitoring can make up the differences of auditing quality caused by the unbalanced development of institutional environment. That is to say the lower level of institutional environment is, the more significant effect that media monitoring improves auditing quality will be.

摘要： 本文以2008-2011年我国A股上市公司作为观测样本，采用主成分分析法和Heckman两阶段模型，考察制度环境、媒体监督对审计质量的影响。研究发现，制度环境较好的地区审计质量较高，媒体监督有助于提高审计质量，特别是媒体的负面报道对提高审计质量有较强的治理效应，媒体监督可以弥补我国制度环境发展不平衡造成的审计质量的差异，即制度环境水平越低，媒体监督对提高审计质量的治理效应越显著。
