In order to verify the Audit committee is working to improve the quality of internal audit, we would devide the board of directors interior audit model into two part,which are the directly under the board model and the audit committee model.In the empirical examination,we had not discovered the relation between the independent internal auditing department and the audit fee also had not discovered the board of directors interior audit pattern may reduce the audit fee.We make the further reason analysis on the reason why they were not connected to both,the analysis indicate that the weakness of internal audit on independence,the not high quality of internal auditor,and the non-correlated between internal auditor and exterior auditor as well as the legal laws and regulations were the all reasons.We suggest that the CPA should take care internal audit pattern;the enterprise must enhance internal audit independence,use board of directors interior audit pattern,strengthen internal audit quality and the communicate between internal audit and exterior audit;the correlation policy standardization construction should be speed up.
