Accounting Information Comparability, Information Environment And Tax Avoidance

As the country's governance foundation and economic operation guarantee,tax revenue plays an important role in the long-term stability of the country.Capital market as a market for information flow,accounting information comparability is an important feature of accounting information quality.Improving comparability may be an effective mechanism to restrict corporate tax avoidance.This paper aims to study whether the comparability of accounting information can restrain corporate tax avoidance behavior?The research of this paper selects the listed companies of Shanghai and Shenzhen A-shares from 2005 to 2017 as sample data,and obtains the accounting information comparability value of company-level in 2012-2017 through the accounting system model;Secondly,construct the comparability and tax avoidance model,explore the impact of comparability on tax avoidance,and then join the external and internal information environment to study the difference between the two in different information environments.Finally,considering the institutional background,the samples are grouped according to the nature of property rights,and the impact of the state-owned and non-state-owned samples on the relationship between the two is explored.This paper also analyzes the validity of the accounting system model in the appendix to ensure the reliability and scientificity of accounting information comparability indicators.Our analysis draws the following conclusions: First,more comparable financial information can affect corporate tax avoidance.Comparability facilitates the tax authorities to detect tax evasion and tax avoidance,thereby inhibiting the tax avoidance of managers.Secondly,from the external and internal aspects of the information environment quality group test,it is found that the suppression of accounting information comparability on tax avoidance is more significant in enterprises with poor information environment.Thirdly,according to the nature of property rights,it is found that the difference between the two groups is small,which proves that the inhibition of tax evading behavior by more comparable information is not affected by the difference of property rights.Finally,through the robustness test,the research results in this paper are scientific and powerful.The research in this paper supports the position of the FASB's emphasis on comparability and usefulness.It suggests that we should further deepen the understanding of the usefulness of accounting information and explore more ways to play the role of comparability.The research also provides useful inspiration for tax authorities and decision makers: tax authorities consider the impact of accounting information comparability when designing tax avoidance testing models to improve the accuracy of tax audit model predictions and improve the detection probability for complex tax avoidance behaviors.Give full play to the restraining effect of comparability on tax avoidance.At the same time,it improves the information environment of enterprises from both internal and external aspects and provides a good information environment for economic development.
