XBRL Effects On Quality Of Accounting Information

With the development of information technology, accounting environment has changed, and with the rapid development of information technology, accounting information need urgently develop.In 2008, the China’s Ministry of Finance has made XBRL as the standard of accounting information.In 2009, the China’s two stock exchanges have set up the "XBRL information platform" and require the listed companies to submit XBRL standard financial reports. XBRL is a new technology in the field of accounting, and due to its inherent scalability, it can make up for the traditional financial reporting in a largely insufficient. It will be the main way of the future financial information disclosure.This paper focuses on the central content of "the impact of XBRL financial reporting on the quality of accounting information" from both theoretical and empirical to research and analysis. On the study of specification, first of all, the paper summarized the relevant literatures, includes two aspects: XBRL and accounting information quality, earnings managemengt and accounting information quality.Then from theoretically to explain the XBRL definition, origin and technology constitute and pointed out the advantages and significance of XBRL financial reporting applications. And then based on the related theory of economics, form the perspective of the efficient market theory and information asymmetry theory, interpret the advantages of XBRL.And then based on the quality characteristics of accounting information, further analyze the function and advantage of XBRL. Then, because the development and promotion of XBRL in China, largely rely on government and regulatory agencies, followed by state-owned enterprises is the promotion and application of XBRL drivers, and drive non-state-owned enterprises XBRL applications. Secondly, the Shanghai Stock Exchange has been ahead of the Shenzhen Stock Exchange in the XBRL application and research. Therefore, the article is based on this to put forward the research hypothesis.In the empirical research part, the paper uses the China A-share listed company board 2005-2012 financial statements as the study sample, and use the level of earnings management to measure the accounting information quality, and use the accruals manipulation(the "DA") form the modified Jones model as the dependent variable. First, this paper use the “T inspection” to test the mean of earnings management before and after the implementation of XBRL, the results show that the DA significant changed before and after the implementation of XBRL. But a lot of factors that cause changes in the value of the DA, this article proceed univariate correlation analysis and multiple regression analysis. The results showed that DA has significant negative correlation of the XBRL. That means XBRL is negatively related to the earings managemengt, and XBRL inhibits the dagree of earnings management. While dividing the overall sample into state-owned companies and non-state-owned companies, the Shanghai Stock Exchange and the Shenzhen Stock Exchange listed companies, in order to verify the different effect of XBRL implementation. Finally, according to the theoretical analysis and empirical data in this paper, put forward the correspongding policy recommendations for our country’s XBRL.
