In this paper, we explore whether companies with good level of corporate governance can effectively attract more foreign investments; on the other side, whether foreign investors will affect corporate governance of the firm is also an important issue what we want to consider about. This study investigates foreign ownership of all the listed and on-the-counter companies in the Taiwan stock market from 1999 to 2013.The empirical result reveals that foreign investors show a preference for companies with good corporate governance, after controlling variables such as size, book-to-market ratio and export ratio. However, evidence for corporate governance affected by foreign investors is not significant.
