Research On Internal Audit Quality Evaluation And Improvement Measures Based On 5M1E Analysis Method

China’s National Audit Office was established in 1983,and China’s internal audit system was also established at the same time.Due to the late development of internal audit in China,the theoretical and practical development level of internal audit lags behind that of foreign countries.The internal supervision of some enterprises is not in place,which leads to the frequent occurrence of such cases as the "problem vaccine" case of Changsheng Bio and the "financial fraud" case of Xintai Electric,which has a negative impact on the healthy development of the capital market.As a result,the state pays more and more attention to the function of internal audit supervision.Based on the above background,the relevant state institutions have issued various notices and regulations,which have given guidance to China’s internal audit work.In 2018,the Provisions of the Audit Commission on Internal Audit(Order No.11)was issued,and in September of the same year,a national symposium on internal audit was held.At the meeting,it was emphasized that strengthening internal audit is an important measure to promote the modernization of China’s governance system and governance capacity.In this environment,how to further improve the quality of internal audit in Chinese enterprises,so that internal audit can achieve the goal of adding value to enterprises and managing enterprise risks is an urgent problem for Chinese enterprises.The evaluation of internal audit quality is the key to improve the quality of internal audit.Combining with various quantitative or qualitative methods,this paper deeply analyzes the factors affecting the quality of internal audit,finds out the existing problems of internal audit and puts forward countermeasures.However,the reality is about the research of internal audit quality evaluation,mostly for the inductive analysis of existing indicators,lacking the update of influencing factors of internal audit quality and practical research on quality evaluation,and there is no unified standard and method for internal audit quality evaluation.Based on this,based on the principal-agent theory,corporate governance theory and information asymmetry theory,and taking 5M1 E analysis method as the evaluation method,this paper constructs a scientific and effective evaluation index system of enterprise internal audit quality.First of all,this paper reviews and sorts out the relevant literature on internal audit quality evaluation of enterprises,and summarizes and analyzes the relevant basic theories;Secondly,under the theoretical framework,the evaluation index system of internal audit quality is established and improved by using the 5M1 E analysis method and the Internal Auditing Standards,so as to optimize the current internal audit quality evaluation mechanism of enterprises.Finally,taking G Group as a case,this paper applies the audit quality evaluation mechanism constructed in this paper to make a comprehensive evaluation,analyzes the existing problems of G Group’s internal audit and puts forward optimization countermeasures,which can provide reference for other enterprises’ internal audit quality evaluation.The conclusions of this paper are as follows:(1)The score of internal audit quality evaluation of G Group is 75.5,which is a good level according to the evaluation standard.The internal audit quality of G Group scored 85 points in the dimension of internal auditors and 86 points in the internal and external environment of internal audit,and the above two indicators accounted for a relatively high weight in the quality evaluation system,so the internal audit quality score of G Group reached a good level as a whole;(2)The main factors affecting the internal audit quality of G Group are the dimensions of information audit tools,audit plans and audit methods;(3)51e method is a very scientific and reasonable evaluation method,and the influencing factors of each dimension of internal audit quality can well correspond to the six dimensions in 51 e method,so enterprises can use this method to make a scientific and objective evaluation of internal audit quality;(4)To improve the internal audit quality of G Group,we should start from the aspects of training audit talents,attaching importance to the construction of information-based audit,introducing audit talents,and implementing the risk-oriented audit plan.
