The smaller of executive power, the more possibility that audit committee professionalism can help reduce the occurrence of internal control deficiencies. In addition, the paper conducts a robustness text：（1） after controlling corporate governance variables, the conclusion that audit committee professionalism can affect internal control quality is still valid, it also shows that corporate governance is also an important factor affecting the internal control quality; （2） the paper divides all sample into seven groups based on the executive power, when the executive power is between l-5, there is significant negative correlation between audit committee professionalism and internal control deficiencies, when executive power increase into 6 and 7, the relationship of the two above is not significant; from the correlation coefficient, the smaller of executive power, the role of audit committee professionalism on internal control deficiencies is more obvious. Significance of the study is to push listed companies to strengthen audit committee professionalism to promote the construction of internal control, reasonably allocate the executive power, improve corporate governance, in order to avoid executives making decisions detrimental to the interests of shareholders, and then executives will play an active role on corporate operation.
