現今半總統制國家數目已經正式超越純粹總統制與內閣制，成為當今最多國家採用的政體類型。近來部分研究關注於半總統制國家的演化發展，除探討半總統制國家朝向內閣制傾斜的演化趨勢外，半總統制國家朝向「總統化」(presidentialisation)發展現象也成為學界關心的新研究焦點。本研究嘗試從半總統制國家朝向總統化發展的角度，探討總統化的定義內涵與演化動力、總統化對於政黨體系的影響，特別著重於總統化對於內閣性質以及內閣穩定度(stability of cabine..

The semi-presidential system has become the most popular regime type in the world, indicated by the number of states that adopted the system having surpassed that of purely presidential system and the parliamentary system since 2000. A number of major studies have recently focused on the evolution of semi-presidentialism; some of the researches have sketched the working mode of parlimentalization of semi-presidential system, and considerable studies have been paying attentions to the development of a semi-presidential system ..

由於先天即存在應然與實然的落差，加上後天多元研究取向所導致立論之分歧，使得半總統制常有評價之爭議。因此，論者在研究中除了應正確認識半總統制的理論內涵，亦需謹慎進行案例的比較或應用，始能產生更精確、細緻的研究成果。本文出於這樣的關懷，將從理論層面出發，透過相關文獻檢閱與不同研究方法之回顧，重新發現半總統制的分析焦點及不同運作類型之內涵及變遷方向。再者，本文也將進行半總統制案例的初步檢驗，以確認半總統制國家實際運作的不同樣態與其中原因。 ..

Since Maurice Duverger proposed the concept of semi-presidentialism in 1980, disputes have increasingly been raised among researchers. Given the gap between norms and operations of semi-presidentialism, as well as the complexities among the relationships of president, prime minister, and congress in the operations of semi-presidential countries, this paper develops a theory-driven comparative framework of this concept. Through re- examining the definitions of semi-presidentialism and the methodology of analyzing its operation..
