摘　　要：风险导向审计模式要求审计师充分识别、评估和判断影响公司经济活动的各种风险因素,因此风险信息披露可能会影响审计师的风险感知进而影响其审计行为,然而现有文献并未关注。本文基于2007～2016年上市公司年度报告"管理层分析与讨论"中与风险有关的信息,从文本相似度视角研究年报风险信息披露与审计费用的关系。研究发现:年报风险信息披露的余弦相似度与审计费用显著负相关,说明年报风险信息披露的余弦相似度降低了审计费用;进一步分析表明,这种负相关关系主要体现在信息质量较高组以及公司显性风险较小组,说明年报风险信息披露的余弦相似度较高是因为公司没有新增风险而并非公司隐藏了风险,余弦相似度较高的年报风险信息披露通过省去部分审计工作程序进而降低审计费用。Risk-oriented auditing requires the auditor to fully identify, evaluate and judge the various risk factors that affect the economic activities of the audited entity. The risk information disclosure can affect the auditor＇s risk judgment and influence its behavior. But the existing literature never paid attention. Based on the data of listed companies from 2007 to 2016, this paper studies the relationship between risk information disclosure in annual reports and audit fees from the perspective of text similarity. Our research findings are that the cosine similarity of risk information disclosure of annual reports is negatively correlated with the audit fee, which is mainly reflected in the group with higher information quality and in the group with lower company-dominant risks. The reason why the cosine similarity of the risk information disclosure of annual report is higher is that the company has no new risks and saves audit fee by reducing the audit procedure.
