Research On Influence Of Efficiency Of Internal Control On Audit Opinion Of Listed Company

To combine the study we found that the factors of audit opinion mainly include audit subject, audit object and audit markets. So far, in our special economic background, our experts and scholars have taken more attention to the normative research about the internal control and external audit, however, empirical research is relative lack. And for foreign scholars, they started early empirical research in this area. The reason for this phenomenon is that the disclosure of internal controls provisions of the proposed is earlier than Chinese, making the internal control data of listed companies can be easily got and facilitate empirical research. At present, China has begun to gradually disclose internal control, making the empirical study of the internal control possible.For these reasons, the paper ,on the basic of the framework of economic theory, combined with the system background of Chinese listed companies in the transition period and the latest corporate governance practices, taking the disclosure of internal control as entry point, makes theoretical analysis and empirical test about effect of efficiency of internal controls on audit opinion, provides the policy advices for effectively playing the role of effective internal controls in corporate governance,objectively evaluating the efficiency of the relevant corporate governance and improving the corporate governance.Research paper is divided into five chapters, each chapter of the research contents and conclusions are as follows: First chapter is introduction .Firstly, significance of the topic of this article; secondly, the generalization of this research framework of ideas and content; finally, the main innovation of this article; second chapter is literature review. By reviewing the previous literature, we found that the research on audit opinion in many aspects is maturing, but at present there is no domestic scholars to answer above-mentioned question from a positivist point of view, this paper mainly undertake studies in this area; third chapter : theoretical analysis describes economic theory that internal control has the impact on audit opinion, analyzing correlation between internal control and audit opinion by the principal-agent theory, asymmetric information theory, signaling theory and insurance theory, paving the way for the assumptions behind; fourth chapter is empirical verification of the internal control efficiency on the impact of audit opinion, the article firstly put forward hypothesis according to the current situation of overseas research and theoretical study, carrying the other influencing factors of audit opinion ,make an empirical test together; fifth chapter includes mainly conclusions,policy proposals and research limitations.Compared with previous studies, the main innovation of this paper is mainly reflected in the following areas: for the first time, audit opinion is studied from the perspective of efficiency of the internal control. The study found, the impact of the information disclosure extent of internal controls and internal supervision non-standard audit opinion is significantly negative correlation; In Shenzhen Stock Exchange, non-standard audit opinion on and disclosure of internal control deficiencies exist significantly positive correlation, from the above analysis of several aspects, we know that efficiency of internal control has significantly impact on the non-standard audit opinion.
