审计意见购买及其监管研究

发布时间：2018-10-26 09:47

【摘要】： 审计意见购买因其潜在不利的经济后果成为理论界与实务界关注的焦点,近年来有关审计意见购买的实证研究取得了较为丰硕的成果。然而,对于审计意见购买的研究往往直接转变为审计师变更的研究,忽视了上市公司管理当局向现任审计师购买审计意见的可能性。因为事务所在对新客户进行审计时,会存在高额的启动成本,若更换审计师,则必然会由于新的审计师要花费新的启动成本而收取更高的审计费用弥补该成本,从而加重被审计单位的负担,使得管理当局变更审计师将会比保留现任审计师需要花费更大的成本。此外,变更审计师会招致监管部门的更多关注,审计意见的提供方,即审计师则可能会要求更高的风险溢价。作为理性经济人,上市公司管理当局向现任审计师购买所需要的审计意见将有可能使管理当局获得更大的收益。至于上市公司到底是向现任审计师购买所需的标准审计意见,还是转向其他审计师购买审计意见,取决于管理当局对于购买审计意见的价格、成功的可能性、可能招致证券监管部门关注度,以及对股票价格的影响等各个方面的理性判断。因此,不仅仅从审计师变更,而且从审计费用的角度来研究审计意见购买行为,将会是一个更为全面更为直接的视角。因而,关于审计意见购买的研究应分别从审计费用的提高和审计师变更两个角度来进行,才能对中国证券市场上的审计意见购买情况获得更深入的理解,为中国证券市场的有效监管提供有价值的实证依据。本文以2004年深沪两市A股上市公司作为研究对象,在前人研究的基础上,运用Logistic回归模型来分别分析审计费用的提高、审计师变更与审计意见购买之间的关系。研究结果发现:意见购买变量与审计费用提高决策具有显著的负相关性,说明样本公司具有明显意见购买动机并对提高审计费用行为存在一定程度的影响,即上市公司可以通过提高审计费用来实现审计意见的购买。但不能验证所有上市公司都能通过变更审计师降低被出具非标准无保留意见的概率,无法证明样本公司具有意见购买动机并对审计师变更行为存在显著影响。
[Abstract]:Audit opinion purchase has become the focus of the theoretical and practical circles because of its potential adverse economic consequences. In recent years, the empirical research on audit opinion purchase has achieved fruitful results. However, the research on the purchase of audit opinions is often transformed directly into the study of the change of auditors, ignoring the possibility that the management of listed companies can purchase audit opinions from the current auditors. Because firms have high start-up costs when auditing new clients, if they change auditors, they will inevitably charge a higher audit fee to cover the cost because the new auditor has to spend new start-up costs. This increases the burden on the auditees and makes it more costly for the management to change the auditor than to retain the current auditor. In addition, the change of auditors will attract more regulatory attention, and the provider of audit opinions, the auditor, may demand a higher risk premium. As a rational economic person, the management of a listed company may obtain more profits by purchasing the necessary audit opinions from the current auditor. Whether the listed company will purchase the required standard audit opinion from the current auditor or switch to other auditors to purchase the audit opinion depends on the management's price for the purchase of the audit opinion and the likelihood of success. May lead to securities regulatory attention, as well as the impact of stock prices and other aspects of rational judgment. Therefore, it will be a more comprehensive and direct perspective to study the audit opinion purchase behavior not only from the perspective of auditor change, but also from the perspective of audit cost. Therefore, the research on the purchase of audit opinions should be carried out from the two angles of the increase of audit cost and the change of auditors, so as to get a deeper understanding of the purchase of audit opinions in China's securities market. To provide a valuable empirical basis for the effective supervision of China's securities market. On the basis of previous studies, this paper uses Logistic regression model to analyze the relationship between the increase of audit cost, the change of auditors and the purchase of audit opinions, taking the A-share listed companies of Shenzhen-Shanghai Stock Exchange in 2004 as the research object. The results show that there is a significant negative correlation between the opinion purchase variable and the audit cost increase decision, which indicates that the sample company has obvious opinion purchase motivation and has a certain degree of influence on the increase of audit cost behavior. That is, listed companies can purchase audit opinions by increasing audit fees. However, it can not be verified that all listed companies can reduce the probability of issuing non-standard unqualified opinions by changing auditors, and it is impossible to prove that the sample companies have an opinion purchase motivation and have a significant impact on auditor change behavior.
