本文將要對於第二次世界大戰戰後迄今的台灣憲法變遷歷程做一整體性的回顧，目的是擬在歷史制度論的途徑下，去瞭解台灣國家由威權政體向民主政體轉型過程中憲法秩序的變化，最重要的是，台灣國家在一九九零年代憲政改革展開前所座落的國內與國際政治經濟歷史結構，以及在既有的歷史結構和憲政制度遺緒的制約下，政治集體行動者如何在特定的關鍵轉捩點上，引爆憲法時刻的改革動能，復而歷經不同制度選擇的辯論和策略互動的過程，成就以〈憲法增修條文〉的制定與修正為中心的憲政改革。

This article is a review of the whole postwar history of the Taiwanese constitutional change. It will follow the approach of the historical institutionalism to examine the constitutional changes during the period of the authoritarian state's transition to democracy. More importantly, it examines to know how the different nationalist political competitors were formed under the given conditions of the domestic and international historical structure along with the constitutional institutional legacies and how they collectively ignited the reformative power at a specific critical juncture during the constitutional moment. It also takes account of how the process of debate over different constitutional choices and its political strategic interaction achieved the Constitutional reform through the making and revising of the Constitutional Amendments.
