信息风险是企业会计信息质量的重要衡量指标之一。本文从理论上分析了制度环境与公司治理对公司信息风险影响的方式与程度均不相同,并运用我国沪深上市公司1999-2006年的数据进行了多元回归分析等实证检验。实证发现:控股股东持股比例与信息风险的关系为先降后升的U型曲线趋势;董事会规模与信息风险负相关;信息风险分为固有信息风险和可操纵信息风险后,公司治理对固有信息风险的影响不显著,而对可操纵信息风险的影响显著;政府干预高的地区,内部公司治理效果更显著,即与信息风险的关系更为显著等。
Information risk is one of the important measures of enterprise accounting information quality. This paper theoretically analyzes the different ways and degrees of the impact of institutional environment and corporate governance on corporate information risk. Empirical tests such as multivariate regression analysis using the data of listed companies in Shanghai and Shenzhen in 1999-2006 are conducted. The empirical results show that the relationship between the controlling shareholder’s shareholding ratio and the information risk is the U-shaped trend of the first drop and then rise; the size of the board of directors is negatively correlated with the information risk; the information risk is divided into the inherent information risk and the manipulative information risk, The impact of information risk is not significant, but the impact on the risk of manipulative information is significant. In areas with high government intervention, the internal corporate governance effect is more significant, that is, the relationship with information risk is more significant.
