With the continuous development of market economy in China,the means of fraud in listed companies are also upgrading.The company managers and administrators begin to realize the importance of perfect internal control to the operation of enterprises.The traditional financial statement audit has been unable to meet the needs of corporate governance.In addition,several standards and guidelines have been issued in succession,which also put forward requirements for the construction of internal control of listed companies.Since 2012,listed companies have been forced to hire accounting firms to audit their internal control.Internal control audit will gradually become the main business of accounting firms.Although China has carried out internal control audit for some time,but Because the theoretical system is not perfect enough,there are still some problems in the business of the firm.Based on the above background,this paper takes the internal control audit carried out by Z firm as a case to sort out the internal control audit process,analyze the problems in the audit process,and put forward optimization suggestions.This paper focuses on the whole process of internal control audit carried out by Z firm to a company,and divides the audit process into three stages.In the planning stage,the importance level of Z firm,risk assessment process and audit schedule are analyzed and elaborated;in the implementation stage,the internal control audit carried out by Z firm is introduced from the enterprise level and business level respectively,and four key processes are selected for detailed description in the business level;in the completion stage,defect evaluation,draft filling and audit review are carried out And other processes.Then this paper analyzes the problems exposed in the audit process of Z firm one by one,and puts forward corresponding improvement suggestions.Z firm is one of the large-scale firms in China,which has carried out many internal control audit businesses.Therefore,the problems in the audit process of Z firm are also common in other firms,which is representative to some extent.The improvement suggestions proposed in this paper for Z firm are also of reference to other firms.Finally,based on the analysis of the audit process of Z firm,this paper draws the following conclusions:(1)compared with the financial audit,internal control audit is more difficult and workload,which requires the firm to pay more attention and arrange auditresources reasonably.The work arrangement of audit plan stage of Z firm is not reasonable,and the firm has not yet correctly understood the difficulty and importance of internal control audit;(2)the implementation stage is the core stage of the whole audit process,and the actual executor of audit procedure of Z firm lacks systematic understanding of internal control audit and corresponding guidance during the implementation of audit,resulting in part of audit procedure The implementation effect is not ideal;(3)the audit completion stage of Z firm is too rough,and the audit quality review effect needs to be strengthened.Through combing the audit cases of Z firm,this paper finally puts forward four enlightenments:(1)firms should change their consciousness in time,correctly understand the importance and complexity of internal control audit work,and reasonably arrange audit resources;(2)firms should actively take effective measures to cultivate compound talents,and constantly update their knowledge system to cope with various audit styles Insurance;(3)if it is necessary for the firm to strictly control the audit quality,it can consider to move forward the review work and control the audit quality in stages;(4)to improve the efficiency of internal control audit,it is not only necessary for the firm to actively make changes,but also the relevant departments of the state should take active actions.
