The Effect Of The Effectiveness And Information Disclosure Quality Of The Internal Control On The Accounting Information Comparability

As one of the requirements for the quality of useful accounting information,the accounting information comparability plays an important role.It not only has a positive effect on the usefulness and relevance of accounting information,but also helps to make a good investment decision and improve the efficiency of capital allocation.So the International Accounting Standards Board(IASB),the United States Financial Accounting Standards Board(FASB),the British Accounting Standards Board(ASB)and the Chinese accounting standards setting bodies and other domestic and international accounting standards setting bodies have been all stressing its importance.At the same time,internal control as an internal governance mechanism that guarantees the authenticity and reliability of financial reports is also drawing increasing attention of companies and regulators both at home and abroad.The promulgation and implementation of the Chinese internal control and regulation system such as the "Basic Standards for Corporate Internal Control" and "Corporate Internal Control Supporting Guidelines" provide research possibility for internal control.Through the combing of relevant research literatures at home and abroad,using the existing research results for reference,based on principal-agent theory,asymmetric information theory,incomplete contracting theory and signaling theory,this paper analyzes the mechanism of the effect of the effectiveness of internal control and the internal control information disclosure quality on the accounting information comparability.On this basis,taking Chinese listed companies as the research object,selecting companies listed on the Shanghai and Shenzhen stock exchanges as research samples,empirical analysis methods were used,through descriptive statistics,correlation analysis,multiple regression analysis,the paper analyzes and verifies empirically the effect of the effectiveness of internal control and quality of internal control information disclosure on the accounting information comparability.The study found that both the effectiveness of internal control and the quality of internal control information disclosure is significantly positively correlated with the comparability of accounting information,which shows that effective internal control helps to achieve accounting information comparability,high-quality disclosure of internal control information helps to improve the comparability of accounting information and the effectiveness of internal control and the internal control information disclosure quality affects each other to enhance the comparability of accounting information.Finally,according to the research conclusions,combined with the reality of Chinese listed companies,this paper proposes some corresponding countermeasures and suggestions.
