审计师行业专长与审计质量——来自财务舞弊公司的经验证据

针对近年来中国资本市场出现的审计失败,以及国内外学术界对审计师行业专长与审计质量关系存在的严重分歧,本文研究发现:审计师行业专长能够提高审计质量,产生上述分歧的原因在于对衡量审计师行业专长指标的恰当选取上。本文认为在中国审计市场上,用行业市场份额来衡量审计师行业专长可能具有普遍适用性。同时,审计师的专业胜任能力不够(主要是十大)和独立性较差(主要是非十大)是资本市场出现审计失败的原因。     

Institutional Ownership and the Selection of Industry Specialist Auditors

This study provides evidence linking corporate governance mechanisms to the choice of auditor, namely industry specialists. Given that institutional investors are likely to prefer higher quality financial reports to lower quality reports, we theorize that institutional investors will influence managers of companies in which they invest to improve reporting quality by using higher quality, industry specialist auditors. Our findings indicate that firms having relatively greater levels of institutional ownership tend to employ industry specialist audit firms. The results of this study contribute to an understanding of an important facet of corporate governance, the selection of a high quality audit firm.     

Earnings quality: Some evidence on the role of auditor tenure and auditors’ industry expertise

Prior studies suggest that auditors with short tenure are associated with lower earnings quality because of the lack of client-specific knowledge and/or low balling. In this study, we examine whether industry specialization of auditors and low balling affect the association between auditor tenure and earnings quality. We find that the association between shorter auditor tenure and lower earnings quality is weaker for firms audited by industry specialists compared to non-specialists. In addition, we do not find results consistent with the low balling explanation.     

行业专长与审计质量——基于投资者和财务报告视角的经验研究

本文从投资者和财务报告视角实证检验了行业专长和审计质量之间的关系。我们利用我国2001～2006年约6000家上市公司样本数据,构造了盈余反应系数模型和操控性应计模型,主要采用多元回归方法进行了统计分析。结果显示:在控制了相关变量的影响后,行业专长事务所审计客户的财务报告质量高于非行业专长事务所审计客户的财务报告质量。这表明行业专长促进了审计质量的提高。     

Auditor conservatism and voluntary disclosure: Evidence from the Year 2000 systems issue

This study further examines the phenomenon of conservative auditor behaviour by considering the level of voluntary disclosure of Year 2000 remediation information in company annual reports. Previous studies have provided evidence of conservative auditor behaviour by examining the link between Big 6 auditor choice and accruals (Francis and Krishnan 1999; Becker et al ., 1998; Defond and Subramanyam 1998). Protecting their reputation capital increases Big 6 auditor incentives to act conservatively to avoid litigation risk. We propose and find that Big 6 auditor clients disclose more Year 2000 remediation information than non–Big 6 auditor clients.     

深交所信息披露考评公告的市场效应研究

本文在对深交所信息披露考评进行分析的基础上,采用事件研究方法对考评公告的市场效应进行了实证分析。研究发现,2002～2006年度,市场对信息披露公告未做出显著反应;但2007年度,市场针对不同的信息披露考评等级做出了显著的理性反应。这一变化,反映了投资者对信息披露质量的关注程度和对深交所信息披露考评机制的认可程度在不断提高。
