摘要
采取2015至2017年沪深A股上市公司作为作为研究样本,在理论分析后提出相对应的假设,首先研究了内部控制质量和盈余管理的相关关系,然后引入股权结构这一变量,考察不同的股权结构状况能否影响内部控制质量和盈余管理原本的相关关系.通过实证分析发现:有效的高质量内部控制能降低公司盈余管理程度,并且在股权属性方面,非国有公司与国有公司相比,内部控制质量对盈余管理的抑制作用更为显著.而股权集中度(第一大股东持股比例)、股权制衡度也会对内部控制质量与盈余在所有权和经营权分离或股权集中度过高的情况下与管理之间的相关关系产生一定的影响,上市公司内部控制质量与盈余管理之间的负向关系会被削弱.
This paper takes the 2015-2017 Shanghai-Shenzhen a-share listed companies as a research sample,and puts forward the corresponding hypothesis after theoretical analysis.First,it studies the correlation between internal control quality and earnings management,and then introduces the equity structure variable to see whether the different status of ownership structure affect the correlation between internal control quality and earnings management.Through empirical analysis,it is found that high quality internal control can significantly reduce the earnings management of listed companies.Moreover,in terms of equity attributes,we found that non-state-owned companies have a more significant effect on the management of earnings than the state-owned companies.The concentration of ownership(the ratio of the largest shareholder)and the balance of equity will also have a certain impact on the correlation between internal control quality and earnings management.There is a separation of ownership and management rights or excessive equity concentration.Under the circumstance,the negative relationship between the internal control quality of listed companies and earnings management will be weakened.
