The conservatism eases an asymmetry of information and at same the time enhances the value of company according to previous studies. The manager, on the other hand, uses earning management using an asymmetry of information as means of own profit seeking.In some prior studies, conservatism and earning management are used as mutual substitutive concepts. The earning management is judged in terms of the relative levels of conservatism employed.In particular, first, we investigate the correlation through regression analysis.Second, the prior studies show the financial characteristics of companies have relation with the earning management presence to specific direction. This research was performed whether or not the degree of conservatism has relationship with earning management to the same direction and used the debt ratio as a company's financial characteristic.The results of this study are not consistent with the prior studies. The relationship between a conservatism and a earning management in this study shows a significant positive relationship in the Basu's conservatism measure. This is corresponding results by Kim and Bae(2006.b)'s study. The significant negative relationship was, on the other hand, showed when we employed the Pennman-Zhang's conservatism measure. It is required more detailed research design to get more consistent findings about the relationship between conservatism and earning management in the future.
