【摘要】： 安然事件之后,美国国会通过了萨班斯——奥克斯利法案(Sarbanes-Oxley Act of 2002 ),禁止注册会计师向审计客户提供大部分类型的非审计服务。在我国,中国证监会《公开发行证券的公司信息披露规范问答第6号—支付会计师事务所报酬及其披露》中则是要求上市公司在年报中按照财务审计费用和财务审计以外的其他费用进行披露。非审计服务的提供及其对资本市场的伤害问题备受各界争议,且目前国内尚无学者从实证研究的角度进行验证,本文拟就此作初步尝试,以2005-2007年报中同时披露审计与非审计费用的A股上市公司为研究对象,以资本成本和买卖价差作为信息风险的替代变量,在国内首次验证了非审计服务的资本市场效应。通过分析国内外对非审计服务的研究成果,对现阶段我国会计事务所的业务多元化与资本市场信息风险的相关性进行实证分析,通过研究以期使各相关主体更好地理解非审计服务的性质和提供非审计服务对资本市场产生的效应,鉴于我国现在上市公司披露财务信息极为不规范的现状,为规范非审计服务的监管提供相关建议,探讨我国注册会计师行业的发展方向。本文通过分析非审计服务对信息风险的两条影响路径,验证以下两条假设:第一,非审计服务费财务信息质量产生正面影响。第二,控制财务信息质量,非审计服务费对信息风险仍然产生正面影响。检验结果表明,非审计服务对财务信息质量产生正面影响,进而对信息风险产生负面影响。即使控制财务信息质量不变,非审计服务仍然对信息风险的度量指标——资本成本和买卖价差产生负面影响。即非审计服务有利于提高财务报告质量并且降低信息风险,并且非审计服务对信息风险的影响不仅仅通过影响财务报告质量作用的。本文在理论上为非审计服务的理论研究提供来自中国的经验证据,在实践上针对我国审计市场激烈竞争的现实,提出相应的监管措施。
[Abstract]:After Enron, Congress passed Sarbanes-Oxley Act of 2002, banning CPA from providing most types of non-audit services to audit clients. In our country, China Securities Regulatory Commission "Standard of Corporate Information Disclosure of publicly issued Securities" No. 6-payment of compensation to Accounting firms and their Disclosure "is a requirement for listed companies to report on the basis of financial audit fees and financial audit in addition to financial audit." Other expenses are disclosed. The provision of non-audit services and its harm to the capital market are controversial, and there are no domestic scholars from the perspective of empirical research to verify this, this paper intends to make a preliminary attempt. Taking A-share listed companies which disclose both audit and non-audit expenses in 2005-2007 annual report as the research object, the capital cost and the spread of purchase and sale price as the alternative variables of information risk, the capital market effect of non-audit services is verified for the first time in China. By analyzing the research results of non-audit services at home and abroad, this paper makes an empirical analysis on the correlation between the diversification of accounting firms' business and the information risk in the capital market. The purpose of this study is to make the relevant parties better understand the nature of non-audit services and the effect of providing non-audit services on the capital market. In view of the fact that the disclosure of financial information by listed companies in China is extremely irregular, In order to regulate the supervision of non-audit services, this paper discusses the development direction of CPA industry in China. By analyzing the two influence paths of non-audit service on information risk, this paper verifies the following two hypotheses: first, the financial information quality of non-audit service charge has a positive impact. Second, control the quality of financial information, non-audit service charges still have a positive impact on information risk. The results show that the non-audit service has a positive impact on the quality of financial information, and then has a negative impact on the information risk. Even if the quality of financial information is not changed, non-audit services still have a negative impact on the cost of capital and the spread of buying and selling price, which is the measure of information risk. That is, non-audit service can improve the quality of financial report and reduce the risk of information, and the influence of non-audit service on information risk is not only by influencing the quality of financial report. This paper theoretically provides empirical evidence from China for the theoretical study of non-audit services, and puts forward corresponding supervision measures in practice in view of the reality of fierce competition in the audit market of our country.
