目的在金宝和奥林巴斯会计丑闻之后，世界范围内越来越关注日本的审计质量。本文的目的是考察2001年至2011年的日本审计市场，以确定大N审计公司与非大N审计公司之间的审计质量是否存在差异，以及这种差异是否在2007年期间发生了变化，当时大型审计公司的数量从四家减少到三家，对审计质量的要求也变得更加严格。设计/方法/方法本研究采用了2001-2011财年日本上市公司的样本。作者使用了5个审计质量的代理变量，并使用倾向分数匹配法对数据进行了分析。结果发现，在控制客户特征(包括在日本测量的经销、海外销售比率和破产风险)时，无论规模大小，日本所有的审计公司都提供相同的服务质量。此外，研究结果显示，尽管2007年普华永道的中央青山事务所解散后，日本审计市场上只剩下三家主要的审计公司，但大N和非大N之间的审计质量差异在2007年前后保持不变。原创性/价值本研究导致了日本缺乏现有审计质量的经验证据，日本是一个审计诉讼风险较低、更注重审计师声誉的国家，考虑到日本审计市场竞争从四大转向三大的显著变化的影响。本研究的研究设计通过使用审计质量的多个替代指标，为现有文献做出了贡献。
PurposeThere has been growing concern worldwide regarding audit quality in Japan after the Kanebo and Olympus accounting scandals. The purpose of this paper is to examine the Japanese audit market from 2001 to 2011 to determine whether audit quality differs between Big N and Non-Big N audit firms and whether this difference, if existed, changed during 2007 when the number of big audit firms declined from four to three and the requirements of audit quality became more rigorous.Design/methodology/approachThis study employs a sample of Japanese listed firms from fiscal year 2001 to 2011. Five proxy variables for audit quality are used and the data are analyzed using the propensity score matching method.FindingsThe authors show that irrespective of their size, all audit firms in Japan provide the same quality of service, when controlling for client characteristics including keiretsu, foreign sales ratio and bankruptcy risk measured in Japan. Additionally, the results suggest that although only three major audit firms remain in the Japanese audit market after the dissolution of PricewaterhouseCooper’s Chuo-Aoyama firm in 2007, the audit quality difference between Big N and Non-Big N remained unchanged before and after 2007.Originality/valueThe study contributes to the lack of existing empirical evidence on audit quality in Japan, a country characterized with low audit litigation risk and more emphasis on auditor reputation, given the influence of the notable change in Japanese audit market competition from Big 4 to Big 3. The study’s research design contributes to the extant literature by using multiple proxies of audit quality.
