Internationalization has been an important issue for the development of most firms in Taiwan. The complexity of information-processing demands resulting from a firm's degree of internationalization will be accommodated by its firm governance. Under this circumstance, the operating and controlling functions are best condition. However, previous studies in Taiwan did not pay much attention on this relation. Through TEJ and Market Observation Post System databases, 191 samples of Taiwanese high-technology public firms are collected and analyzed. Using OLS regression and Logistic regression models, the study finds that the higher firm's degree of internationalization is, the higher the CEO's compensation of the firm is; while the higher firm's degree of internationalization is, the lower the CEO's stock holding ratio of the firm is. In addition, the interaction between diversification and a firm's degree of internationalization is positively related to the level of its CEO's compensation.
