Research On Internal Control Evaluation System Of Enterprises

The theory of internal control has been developed to the stage of a comprehensive risk management framework for integration. However, Lehman, Merrill Lynch, AIG, the United States claimed to have effective internal control large companies have a great impact on the financial crisis. In the end, the collapse of Lehman Brothers, Merrill Lynch was acquired, and AIG is supported by the U.S. government to tide over their difficulties. This is a huge challenge of internal control theory:Since the important feature of the internal control is to reduce the risk, why do COSO "Enterprise Risk Management-Integration Framework"(2004), the big companies will still go bankrupt or be acquired? To answer this question, in2008, the domestic and international theory and practical circles set off another round of internal control of the boom. In2010, China promulgated the "enterprise internal control basic norms" and its supporting guidelines and provisions in the Shanghai Stock Exchange and the Shenzhen Stock Exchange listed on the Main Board of the Company since January1,2012start, and encourage non-listed large and small enterprises to advance the implementation of. Evaluation of internal control, not only meet the enterprises to improve their internal control needs of the situation, and also meet the requirements of the policy. Therefore, the internal control evaluation is an important issue for enterprises must face.The evaluation of internal control refers to the evaluation of the overall evaluation of effectiveness of internal control system, and the formation of evaluations to identify internal control deficiencies. Internal control evaluation guidelines on the principle of internal control evaluation, contents, procedures, defects identified theoretical issues to make certain provisions, but these provisions are too general, can not provide specific internal control evaluation practice guidance. Currently, academia internal control evaluation conducted extensive research, most of these studies, however, stand in the point of view of the external evaluators rely solely on the information disclosed by the company. Therefore, the evaluation of the accuracy is questionable, and can not guide practice, is also not conducive to the improvement of the company’s internal control. Therefore, there is an urgent need to establish a certain operability internal control evaluation system, to guide internal control evaluation practices. Combing the basis of comparison of domestic and foreign internal control theory, combined with the reality of our country, and pointed out that the role of the board, management, internal audit and external certified public accountant in the evaluation of internal control, clear the main body of the internal control evaluation, and comparative analysis of the two commonly used internal control evaluation method-detailed evaluation method and the similarities and differences of the risk-based approach, and pointed out the advantage of the risk-based approach, clear evaluation of internal control and, on this basis, based on the risk-based approach to build Evaluation of Internal Control system. First, the enterprise’s internal control into the corporate level and at the operational level, and in accordance with the internal control basic norms ", the central enterprise comprehensive risk management guidelines" document lists all levels of internal risk control points, followed by risk point of distinction, to focus on the main risks, we use the analytic hierarchy process to empower risk point. Again, the paper describes a method of testing the effectiveness of internal control, and the risk points. According to the test results, identify internal control deficiencies, and draw a comprehensive evaluation of the results of the effectiveness of internal control. The evaluation results proved that build the internal control evaluation system of internal control evaluation practice has certain guiding significance.The enterprise internal control is divided into a corporate level and operational level, discusses the risk-based approach to the implementation of the internal control evaluation process, summarized the method of testing the effectiveness of internal control, and the establishment of a comprehensive evaluation of internal control model, has a certain theoretical significance and application value.
