作為德國歷史上的第一個民主政體─威瑪共和從誕生開始就是一個「生病的民主」，也是一個「沒有民主人的民主」。威瑪憲法的制定者除了架構起所謂的「程序性民主」之外，同時更在議會制的基礎上賦予民選的總統強大的權力─半總統制，加上欠缺民主文化，以及存在著反體制的政黨，致令威瑪憲法像是特洛伊木馬。最後在議會政治失敗的亂局中，希特勒(Adolf Hitler)率領納粹黨徒從木馬中一躍而出，用原本是保護民主的權力將民主政體合法地謀殺掉。 二戰後的聯邦德國..

Both France and Taiwan’s political systems are semi-presidential. However, “cohabitation” in French constitutional experience has occurred three times while Taiwan has never seen “cohabitation” until now. Finding the reason for this difference is the central question of this paper. By using the game theory as an analysis tool, the paper explores how the institutional design influences the actors’ strategic interactions, which underlies the discrepancy between France and Taiwan in “coh..
