产品市场竞争对审计收费可能具有双重影响。根据代理成本理论,产品市场竞争能够缓解管理层和股东之间的代理问题,审计师会因此降低固有风险的评估水平并减少审计工作量,审计收费会因此降低。根据经营风险理论,产品市场竞争会增加企业的经营风险和审计师的经营风险,审计师会收取风险溢价,审计收费会因此升高。本文以我国2007至2011年6709个上市公司年观测作为研究样本,实证发现,上市公司面临的产品市场竞争强度对审计收费具有显著的负向影响,即代理成本效应起主导;上市公司所处的竞争地位对审计收费具有显著的负向影响,即经营风险效应起主导。以上结论说明,审计师在审计业务执行过程中会同时考虑上市公司所处行业的产品市场竞争状况和在行业内的竞争地位,并在收取审计费用时区别对待。

英文摘要：

Product market competition may have double impacts on audit fees. According to the agency cost theory, product market competition can mitigate agency problems between management and shareholders, auditors will reduce the level of inherent risk assessment and reduce audit workload, audit fees will reduce. According to the business risk theory, product market competition will increase business risks and operating risks of the auditor, who will charge a risk premium, audit fees will increase. Using a sample of 6709 firm-year observations from the Chinese stock market for the period of 2007-2011, this study finds that while the product market competition intensity has a significantly negative impact on audit fees, which means that agent cost effect plays a dominant, a company＇ s competitive position in the industry has a significantly negative impact on audit fees, which means that business risk effect plays a dominant. The conclusions above mean that, in the audit business execution process, the auditor will take both the product market competition intensity of the industry in which the company operates and a company＇ s competitive position in the industry into consideration, and make distinction when charging audit fees.
