非整合审计可以提高盈余质量吗?——来自PSM 的新证据

Can Non-integrated Auditing Improve Earnings Quality?New Evidence from PSM

基于我国内部控制审计全面且强制实施背景下,选取2013—2018年沪深A股上市公司作为研究样本,对实施非整合审计上市公司的盈余质量及其微观机制进行实证分析,并采用倾向得分匹配分析法(PSM)解决样本选择偏误问题。研究结果表明:企业实施整合审计和非整合审计对于盈余质量的提升存在显著性差异,相较于整合审计,企业实施非整合审计能够显著提升上市公司的盈余质量;非整合审计的实施能够显著提升公司内部控制的有效性,且随着内部控制有效性的提高,企业执行非整合审计对于盈余管理的抑制作用也更加显著。

Under the background of comprehensive and mandatory implementation of China’s internal control audit,with A-share listed companies in Shanghai and Shenzhen from 2013 to 2018 as the research sample,this paper makes an empirical analysis on the earnings quality and micro-mechanism of the listed companies implementing non-integrated audit,and uses the propensity score matching analysis method(PSM)to solve the problem of sample selection bias.The study finds that there is a significant difference in the improvement of earnings quality between integrated audit and non-integrated audit.Compared with the integrated audit,the implementation of non-integrated audit can significantly improve the earnings quality of listed company,while the implementation of non-integrated audit can significantly improve the effectiveness of internal control of the company.With the improvement of the effectiveness of internal control,the implementation of non-integrated auditing of enterprises has a more significant inhibitory effect on earnings management.
