A Brief Study On Earnings Management's Influence On Accounting Information Quality

As we all known, the quality of accounting information has always been the focus of our society. While the new Accounting Standard for Enterprises, which was issued in 2006, is aimed at standardizing the accounting confirmation, measurement and report within a corporation and guaranteeing accounting information authentic and valid and improving it.But high-quality accounting standard does not mean high-quality accounting information, for there are many factors which restricting its improvement, and the most important factor is management of enterprise surpluses. If we want to ensure accounting information quality, we must take this factor into account. So it's significant to study earnings management, especially on the changes of management methods under the influence of new Accounting Standard for Enterprises.In this article, with the informativeness of earnings as the main measurement of the quality of accounting information, the author makes a study of our A-share listed companies'data from 2006 to 2007 in the regression analysis method and draws lessons from Jones Model of cross-section correction at the same time. We firstly find that new Accounting Standard has overall reduced the space of earnings management and improved the quality of accounting information. Then with empirical study on another model, we find there are still some management instruments playing their roles, like debt restructuring and investment income, while assets disposal was under control. That is to say, new instruments are emerging in an endless stream and the old ones still exist.
