This thesis is an exploratory study of the composition of governing elites on Taiwan. Secondary data analysis is the primary method used in this research. The data of elite profiles are mainly collected from the following sources: (1) a website database on historical figures from the Academia Historica; (2) the official address-book on superintendents of the Executive Yuan and its departments; (3) Who's Who of the Republic of China. This research compared personal variables of governing elites of two regimes, such as party membership, gender, ethnic group, area, generation, and pervious profession. In this way, this study tries to answer whether the characteristic differences between KMT and DPP governments will lead to the different characteristics of the governing elites as depicts in the theory of representative bureaucracy. After analyzing the composition of governing elites of the two regimes, we have following five findings. First, there is a long way to go to gender equality in governing elites regardless a little progress has been made by the DPP. Second, governing elites of DPP government are younger than KMT government. Third, much less elites of mainland Chinese origin are appointed by the DPP than the KMT. Forth, DPP appointed much more southern Taiwanese elites than the KMT does. Lastly, governing elites in DPP government are coming from a more diverse prior professions than those in the KMT government.
