【摘要】：2012年是我国强制性内部控制审计实施年。国外研究发现,强制性内部控制审计加重了企业的审计成本负担,这与经典的修正内部控制缺陷导致审计费用下降的观点并不一致,被称之为SOX404的"审计费用之谜"。目前,我国还比较缺乏对这一研究议题的深入检验。本文以财政部、证监会2012年联合制定的《关于2012年主板上市公司分类分批实施企业内部控制规范体系的通知》作为准自然实验,采用目前推崇的政策评价方法——双重差分法检验强制性内部控制审计对审计费用的影响,并使用断点回归、内生性检验、安慰剂检验等对研究结果进行了稳健性检验。结果显示,相对于不受该项政策影响的企业来说,实施企业在新政执行后,其审计费用显著上升。进一步,本文检验了影响该政策效应的具体机制。研究发现,中国版SOX404能够通过内部控制缺陷披露、诉讼风险和自愿性整合审计这三种机制促进企业审计费用的上涨。本文的研究有助于澄清中国版SOX404的"审计费用之谜",便于行业的利益相关者更好地认识强制性内部控制审计的成本效益性,并为决策制定者进一步完善我国内控规范体系提供政策参考。
[Abstract]:2012 is the year of implementation of mandatory internal control audit in China. Foreign studies have found that mandatory internal control audit increases the burden of audit costs of enterprises, which is inconsistent with the classical view that internal control defects lead to the decrease of audit costs. It is called "the puzzle of audit fee" by SOX404. At present, our country still lacks the thorough test to this research topic. In 2012, the Securities Regulatory Commission jointly formulated the notice on the classification and batch implementation of the enterprise internal control standard system for listed companies on the main board on 2012, as a quasi-natural experiment. The dual difference method, which is the policy evaluation method, is used to test the impact of mandatory internal control audit on audit cost, and breakpoint regression and endogenous test are used. Placebo tests and so on have tested the results of the study. The results show that, compared with those enterprises not affected by the policy, the audit costs of the implementing enterprises increased significantly after the implementation of the New deal. This paper examines the specific mechanisms that affect the effect of the policy. The study found that the Chinese version of SOX404 can be disclosed through internal control defects. The three mechanisms of litigation risk and voluntary integrated audit promote the increase of audit cost. The research in this paper is helpful to clarify the "mystery of audit cost" of Chinese version of SOX404, so that stakeholders in the industry can better understand the mandatory. The cost effectiveness of internal control audit, It also provides policy reference for the decision makers to further improve the internal control standard system of our country.
