| In 2019,as the stocks of many listed companies related to agriculture under the "super pig cycle" are sought after by the market,behind the feast of soaring stock prices,the performance explosion drama of relevant listed companies in China has been frequently staged,which has attracted extensive attention from the capital market.In recent years,with the Ministry of Finance’s revision of financial instruments,income and other accounting standards,the application of Accounting policies of Chinese enterprises has gradually been in line with the international standards,the stability of accounting policies has been enhanced,and the behavior of accounting policy changes will be more diversified.It increases the audit risk of auditors judging the reliability of "enterprises make appropriate adjustments to accounting policies according to their own operating environment and financial conditions".With the "performance explosion" of many listed companies,the reliability and objectivity of enterprise accounting information quality are questioned by the market.The degree of accounting policy change can reflect the degree of its impact on the quality of financial information from the side,and then as a signal to the CPA.Based on this,the research question of this paper is drawn,whether auditors can pay attention to the risks brought by accounting policy changes and objectively issue audit opinions,and whether a good internal control environment of enterprises will have an impact on the issuance of audit opinions of annual auditors of enterprises with accounting policy changes.This paper first defines the core concepts of accounting policy change and audit opinion type,and further explores the relationship between accounting policy change and audit opinion type from the perspective of information asymmetry and selective financial information disclosure based on classical theories such as principal-agent theory and financial information disclosure hypothesis.Secondly,the internal control quality of listed companies is included in the study of the relationship between the two,and the moderating effect of internal control quality is explored.Thirdly,group regression analysis is conducted on the samples to explore whether there are differences in the risk prevention consciousness of auditors in different groups from the perspective of the nature of accounting policy changes,property rights and whether Dong Jinggao is also a shareholder.This paper takes China’s A-share listed companies from 2015 to 2020 as the research sample,uses Logistic regression model to study the relationship between accounting policy changes and audit opinions,and analyzes the influencing factors.It is found that there is a significant positive correlation between accounting policy changes and non-standard audit opinions of listed companies,and the perfect internal control system of listed companies can significantly inhibit the positive correlation between accounting policy changes and non-standard audit opinions.When studying the effect of the five elements of internal control on the relationship between accounting policy changes and non-standard audit opinions,it is found that the three elements of risk assessment,control activities,information and communication have a more obvious inhibition effect on the correlation between the two.At the same time,further research found that the positive impact of accounting policy change on non-standard audit opinions was more significant in the sample group of "malicious accounting policy change",the sample group of state-owned enterprises,and the sample group of Dong Jinggao’s concurrent shareholders.The above results are still valid after the robustness test.This study has certain reference significance for standardizing the accounting policy change behavior of listed companies,reducing the risk of auditor clients taking on and improving the effectiveness of relevant regulatory authorities’ policy making. |
