Based on the data of Shanghai and Shenzhen A share state owned listed companies from 2012 to 2014,this paper empirically examines the effect of background characteristics of top management team(TMT)on the companys internal control quality.The result shows that:the educational degree of TMT is positively correlated with the quality of internal control,the average age and tenure of TMT is negatively correlated with the quality of internal control.When the proportion of women in the listed Corporation is more than the industry median,it is positively correlated with the quality of internal control,otherwise,the reverse is true;when the average size of the listing corporation is less than the median of the industry,average size on the quality of internal control has a negative effect.We further theoretically analyzed the influencing mechanisms of the vertical dyad characteristics differences of the president and TMT,and found the gender,age and tenure vertical dyad characteristics differences of the president to TMT are of significant positive correlation with the quality of internal control;the higher the educational degree vertical dyad linkage characteristics of the president to TMT,the lower the quality of internal control.The conclusion of this study will be helpful to the construction and maintenance of the internal control system of the state owned listed companies,and it will also optimize management team structure,improve the quality of internal control and better the corporate governance structure.
