The Impact Of Internal Control Attestation On The Quality Of Financial Statement Audit

In recent years,listed companies have strengthened the strength of internal control,but even after the implementation of internal control,financial fraud cases continue to occur,making the external investors still question the quality of the company's financial reports.Behind these events,they can always see the shadow of the internal control of the listed companies.Both theoretical and practical circles have begun to study the effectiveness of internal control design and implementation of listed companies seriously.As early as 1980,the CPA Committee proposed that the listed companies submit self-evaluation reports on internal control every year,and also have third parties certified certified public accountants.In 2006,our country introduced the concept of internal control identification for reference to other countries.It was the first time that the certified public accountants of the accounting firm should verify the effectiveness of the internal control of the company and express their opinions while auditing the financial reports of the listed companies.However,the internal control identification report of the listed companies is voluntary disclosure.With the development of practice,China has promulgated corresponding internal control regulations and guidelines in 2008 and 2010,emphasizing the importance of implementing internal control authentication.The publication of these documents means that internal control authentication has gradually become a hot spot of research.Based on the above background,this paper first introduces the related concepts and theories of internal control authentication.Secondly,based on the knowledge spillover theory and synergy theory,this paper discusses the correlation between the internal control authentication and the quality of the financial report audit,and puts forward the research problems.Thirdly,we collected the data of Shenzhen and Shenzhen manufacturing listed companies from 2014 to 2016 as the research samples,and verified the hypothesis from the perspective of empirical analysis.Through research,it is found that providing internal control authentication service to listed companies can improve the audit quality of financial report by restraining the level of earnings management,and find that the type of assurance report has no effect on the audit quality of the financial report.Finally,in view of the research findings and the development of internal control attestation,this paper puts forward some pertinent opinions.The empirical data obtained from this study can help relevant departments to formulate policies on internal control attestation,which is of practical significance.
