The Research For Voluntary Accounting Changes Of Listed Companies

The object of accounting is providing accounting information for decision-making, and this is the ultimately cause of its being and development. If accounting can not providing useful information, it wouldn't exist and couldn't be greatly developed in the long history river of human's economy.Accounting information is the result accountants processed using specifically procedure, principle and method, so what procedure, principle and method accountants choose will surly affect the quality of accounting information—the relativity and reliability. Thus researching accounting choice is very important. Why accountants choose this policy and estimation but other policy and estimation, what results this choice will bring, how relative entities join the accounting choice and along with the change of society economic, how accounting choice changed, all this are the main content of accounting choice researching.Accounting is a dynamic process. But because accounting practice is complicated, accountants always change their choices. That is named accounting changes. Accounting changes not only include changes in policy, but also include changes in estimation. At some times, effects of estimation changes are much more important than effects of policy changes.My paper researched voluntary accounting changes of listed companies in our country, and we found out accounting choice behavior in our country are very opportunistic. Listed companies changed accounting policy and accounting estimation not to improve relativity and reliability of accounting information, but to realize other objects such as going public, share allotment and keeping away form delisting. Voluntary accounting changes have been one instrument which listed companies used to control outstanding achievement. We also found out that listed companies are more likely to use accounting estimation changes but accounting policy changes, and voluntary accounting changes are correlative with compellent accounting changes.The right of accounting choice is one kind of remnant controlling right belonging to corporation's supervisors. Because system of supervising corporation's supervisors is invalid, opportunistic behavior in accounting choice come into being. To perfect accounting principles is necessary for correcting the behavior of accounting choice, but to constitute scientific company fathering organization is the basis of resolving this problem. In addition, extending the approach of other relative entities to join accounting choice and strengthening the supervising function of CPA are also important for correcting the behavior of accounting choice.
