The empirical results are summarized as follows : First, In relation to effects of ownership structure on firm value, there is the non-linear relationship between major(and foreign) shareholder's holdings and firm value. So the results(the compromise hypothesis) by prior researches(Morck et al. 1988 and so forth) is supported. However Institutional shareholder's holdings do not show the significant results. Second, In relation to effects of outside directors on firm value, equally the results of prior researches(Vafeas 2000, Choi et al. 2004), the higher the ratio of outside directors in the board, the higher firm value. Also there is the non-linear relationship between outside directors ratio and firm value. Furthermore, the higher the possibility of outside directors election in the board, the higher the relationship between ownership structure and firm value. As the economic importance of KOSDAQ is more increase, the researches of KOSDAQ should be more realized.
