审计市场结构与审计质量:来自中国证券市场的经验证据

本文以我国证券市场2004年~2005年的上市公司为研究样本,使用调整后的KS模型估计出的公司操纵性应计利润的绝对值作为审计质量的衡量指标,考察了审计市场结构和审计质量的关系。研究发现在控制了影响审计质量的相关变量之后,市场结构与审计质量存在以下关系:审计市场集中度与审计质量成正相关关系;市场的进入退出壁垒越高,审计质量越高;但审计师的行业专长不但没有提高审计质量,反而在一定程度上降低了审计质量;审计市场的强地域性与审计质量也没有明显的相关关系。

Auditor Market Structure and Audit Quality: Empirical Evidence from the Chinese Securities Market

Using the data of those listed firms during 2004 and 2005 in the Chinese securities market,and measuring audit quality by the discretionary accruals calculated by the KS model,this paper investigates the relationship between auditor market structure and audit quality.We find that after controlling the influence of other variables,auditor market structure and audit quality existing the flowing relationship: audit market concentration and audit quality has positive correlation;the market enter barrier and withdrawal barrier to be higher,the audit quality is better;the auditor's industry expertise not only failed to improve the audit quality,but lower the audit quality;the market's localization has no obvious relationship with the audit quality.
