This study investigates the effects of improved corporate governance on the firm value as well as the firm performance. We also examine if there is any causal relationship between corporate governance and the foreign investors¡¯ share holdings. For these purposes, we utilize the corporate governance index data for the period of 2006 through 2010 published by the Korea Corporate Governance Service. The main results of this study are as follows: Firstly, firms with relatively good corporate governance yield better firm performance, which in turn results in greater firm values. Specifically, we found through regression analyses that corporate governance index is significantly positively related with EBIT/SALES, Tobin's Q, and PBR. Secondly, corporate governance index has a significantly positive impact on the ownership of foreign investors. Thirdly, the foreign investors' share holdings affect positively on the firm performance measured by PBR, Tobin's Q, and abnormal returns.
