2001年开始实施的审计收费信息强制披露规定,是改善了我国审计环境还是恶化了审计环境?本文采用三种相互补充的研究设计具体考察2001年开始实施的审计收费信息强制披露政策对我国审计环境的影响,结果发现强制披露规定颁布日国内会计师事务所主审的上市公司的累计异常回报高于中外合作会计师事务所主审的上市公司,进一步研究发现,在审计收费信息首次披露后年度(2002-2003),国内会计师事务所的审计收费与中外合作会计师事务所的审计收费的差异显著缩小、审计质量显著提高。而且上述发现在国内小会计师事务所表现更为明显。这基本上支持审计环境改善的假说。

Consistent with the audit environment improvement hypothesis, the companies audited by local CPAs had higher cumulated abnormal return around the rule promulgation than the companies audited by international CPAs, and the audit fee and audit quality of local CPAs had improved relative to international CPAs after the rule promulgation.
