股权集中度、内部控制审计意见与财务报表审计质量——基于沪深A股上市公司2013-2016年的经验数据

Equity Concentration, Internal Control Audit Opinions and Audit Quality of Financial Statements: Based on the Experience Data of A-share Listed Companies in Shanghai-Shenzhen from 2013 to 2016

以沪深两市2013—2016年A股722家上市公司面板数据为样本,主要运用实证研究法和中介效应研究方法分析了2012年强制性内部控制审计以来的内部控制审计意见、股权集中度、财务报表审计质量之间的关系。研究发现:内部控制审计意见与财务报表审计质量是显著正向关系,股权集中度与财务报表审计质量为显著反向关系;同时,股权集中度对内部控制审计意见存在显著负向影响;股权集中度对财务报表审计质量的影响有一部分是通过内部控制审计意见的中介作用实现的。

Based on the data of 722 A-share listed companies in Shanghai and Shenzhen from 2013 to 2016 as samples, the paper mainly uses empirical approaches and the mediation effect research methods to analyze the relationship between internal control auditing opinions, equity concentration, and the financial statements audit quality since the mandatory internal control audit in 2012. It is found that the audit opinions of internal control is positively correlated to the audit quality of financial statements, and the ownership concentration is negatively correlated to the audit quality of financial statements. At the same time, equity concentration has a significant negative effect on internal control audit opinion. The influence of equity concentration on the audit quality of financial statements is partly realized through the intermediary role of internal control audit opinions.
