本文以發行於五○年代的《自由中國》半月刊為文本，指出臺灣五○年代是國民黨面對反共反攻格局所進行的改造運動及自我定性於革命民主政黨的年代，身處其中的《自由中國》的政治論述對反共反攻局勢中的詮釋，與實踐自由、民主、法治等價值與行動問題的處理，孕育了該刊主動變動發言位置的動能。國民黨型塑政治論述場域的強大力量及《自由中國》在其中的持續抗壓的歷程，乃形成臺灣五○年代政治論述場域。民主、個人自由、法治及政黨政治等乃成為這個場域中，以特定論述策略而進行的政治論述主題。

In this essay, the author takes Free-China Bimonthly as an example, a political criticism magazine published in 1950s Taiwan, and plans to prove that (1) KMT Reformation was the unique factor in the field of 1950s Taiwan political discourse; (2) the re-self-definition of revolutionary democratic party was the outcome of KMT reformation; (3) the political discourses between Free-China Bimonthly and KMT constituted the main outline of field of 1950s Taiwan political discourse; (4) 'democracy,' 'individual freedom,' 'rule of law' and 'party politics' were the unavoidable subjects with a set of unique discursive strategies in 1950s Taiwan political discourse.
