This paper focuses on the related patterns of national elite conditions of the CCP during the reform era and the KMT in the martial law period, so as to explore how party-state systems can maintain their ruling status. Drawn from the trend analysis and the historical analysis, this paper finds that, for the CCP, there was a transitional process in which the elite unity became weakened and then strengthened again. And nowadays the elite configuration remains ideocratic, composed of the narrow differentiation and the strong unity. By contrast, the elite configuration in the KMT substantially changed from ideocratic to fragmented during the martial law period, including toward wider differentiation and weak unity. The evolution of elite condition is important for determining the survival of a party-state system, especially provide a basis for the emergence of intra-party conflicts. By comparing the two different cases, this paper suggests that how to avoid the elite condition toward fragmented is crucial for the CCP's political survival in the future.
