Research On Cooperative Supervision Of Certified Public Accountant Industry Based On Evolutionary Game

Under the background of registration system,certified public accountants bear more important responsibilities for the quality control of information disclosure.The government supervision department no longer conducts substantive audit on the authenticity and accuracy of information disclosure of issuers,but instead conducts substantive audit on the quality of information disclosure of issuers by certified public accountants,which also poses greater challenges to the supervision of certified public accountant industry in China,establishing an effective supervision system is an important way to promote the supervision efficiency of certified public accountant industry.However,at present,there are some problems in China’s certified public accountant industry supervision,such as unclear responsibilities of regulators,overlapping and repeated supervision,lack of industry self-discipline and insufficient supervision,which greatly reduce the supervision effect.Therefore,how to strengthen the supervision of certified public accountant industry and effectively regulate certified public accountant behavior is of far-reaching significance for maintaining the stability of China’s securities market and ensuring the smooth landing of the registration system.In order to explore the influencing factors and mechanism of certified public accountant industry supervision,so as to improve the cooperative supervision system of Chinese government supervision departments and industry self-regulatory organizations on certified public accountant industry,promote the efficiency of certified public accountant industry supervision,and realize the effective guidance and supervision of certified public accountant industry.Firstly,this thesis combs the relevant theoretical research and policy guidelines of certified public accountant industry supervision,and analyzes the supervision mode,relevant laws and regulations and existing problems of certified public accountant industry in China.Focusing on the new characteristics of China’s securities market supervision under the background of registration system,this thesis puts forward a collaborative supervision system combining the administrative supervision of government supervision departments with the industry self-discipline of industry self-discipline organizations.Secondly,this thesis takes the collaborative supervision of the certified public accountant industry by government regulatory departments and industry self-regulatory organizations in the initial public offering process of China’s securities market as the research object,builds an evolutionary game model among certified public accountant,industry self-regulatory organizations and government regulatory departments based on the collaborative theory and prospect theory,and analyzes the evolutionary stability strategies and influencing factors of the model under different conditions,and then simulates the ideal stable evolution state and evolution trend of the evolutionary game model under different factors by using Matlab.The results show that the behavior choice of certified public accountants is mainly influenced by the punishment of government regulatory departments and industry self-regulatory organizations.The behavior choice of government regulators and industry self-regulatory organizations is mainly influenced by the supervision cost,perceived difference and reputation losses,only by properly encouraging the positive behaviors of government regulatory departments and industry self-regulatory organizations,reducing the regulatory costs and perceived differences between the two sides through institutional norms,enhancing the social reputation effect,and at the same time,increasing the punishment for certified public accountants’ illegal auditing behavior can the certified public accountant industry be effectively supervised.Finally,based on the above-mentioned influencing factors,this thesis puts forward corresponding suggestions to improve the cooperative supervision mechanism between government supervision departments and industry self-regulatory organizations from four aspects: perfecting the cooperative supervision system,realizing resource sharing and intercommunication,strengthening the complementary function scope and strengthening the reputation constraint effect,hoping to further improve the supervision and management system of China’s certified public accountant industry and promoting the supervision efficiency of China’s certified public accountant industry.
