上市公司内部控制审计与年报及时性——基于OLS与分位数回归的证据

Internal Control Auditing and the Timeliness of Annual Report:Evidence Based on the Evidence of OLS and Quantile Regression

及时性是会计信息质量的重要特征之一,内部控制审计通过提高内控质量与审计效率来促进年报披露的及时性。以2010—2012年沪深主板A股3894家上市公司为样本,运用OLS与分位数回归对内部控制审计与年报及时性进行了理论分析与实证研究。研究发现:虽然内部控制非标审计意见、内部控制缺陷以及内控缺陷整改会导致年报时滞延长,但在总体上内部控制审计促进了上市公司年报及时披露。分位数回归结果还表明,在不同的年报披露时滞水平下,各影响因素对年报延迟的影响效果不同。

Timeliness is one of the most important characteristics of the accounting information quality. Internal control audit influences the timeliness of annual report through improving the quality of internal control and audit efficiency. Based on the Shanghai and Shenzhen Stock Exchange from 2010 to 2012 as samples of 3894 listed companies, and by using the OLS and quantile regression, the paper makes a theoretical analysis and empirical research on the effect of the internal control auditing on the timeliness of annual report. The study finds： although the non - standard audit opinions of internal control, internal control defects and defects rectification can result in the annual report delay, generally, the internal control auditing promotes the annual reports disclosure of listed companies earlier. Quantile regression results show that under different time of the annual report disclosure delay, the influence of various influence factors on the annual report delay effect is different.
