| Accounting conservatism has been almost six hundred years when it first referred in the Civil and Commerce Law, but researches on its existence and its impact on the business started in the last century90s, until early21st century, some scholar began to explore the influence factors to accounting conservatism. Now, accounting conservatism, as one of the requirements of accounting information quality has been listed in accounting standards of world’s major nationals, and the requirements become more and more strict. As special corporate characteristics, assets specificity, corporate scale and property can affect the company’s internal and external governance, so they can affect accounting conservatism. First, this paper searched related literature, and found there are little literature about the relationship between the three special corporate characteristic factors and accounting conservatism, so I select this field as my research direction. Then, based on the analysis of contract theory, property right theory and company governance, considered the actual situation of our country, I analyze my assumptions. In this paper, I choose Basu’s model to prove my assumptions. Through the empirical analysis, we get conclusions:(1) When the asset specificity is higher, the accounting conservatism is higher;(2) The larger the company business is, the higher the accounting conservatism is.;(3) State-owned enterprise has lower accounting conservatism than others. With the improvement of accounting conservatism, company value will get promoted, so I give some advices to help companies improve their accounting conservatism level from the aspects of company and policy. At last, I summarize the limitation of this paper and put forward the direction of future improvement. |
