自民主轉型以來，臺灣政黨間主要的政策競爭為與中國關係的不同立場。本文認為基於過往不同的統獨立場，臺灣兩大政黨會強調殊異的論述框架，使己方立場更具說服力。本文分析臺灣立法院在1996-2020年期間委員們關於中國議題的總質詢發言，透過「潛在語意尺度」分析發現，國民黨的立委更強調與中國交流能帶來利益，而民進黨則更頻繁提及中國對臺灣具差異和威脅。當臺灣經濟表現較不理想、而中國經濟表現較優越時，立委們更傾向將中國描述為利益所在；而產業結構上較仰賴農漁業的選區所選出的立委，也更強調中國可帶來經貿利益。

Since Taiwan’s democratic transition, its relationship with China has remained the most salient issue in party politics. Although extensive studies have examined public opinion, there has been a lack of systematic research on how political parties frame this issue rhetorically. Using the Latent Semantic Scaling model, this study analyzes the speeches of Taiwanese legislators on China-related issues from 1996 to 2020. The results show that the Kuomintang emphasizes the benefits of engagement with China, particularly highlighting “communication dialogue” and “economic benefits.” In contrast, the Democratic Progressive Party often discusses threats from China, focusing on “security” and threats to “democracy and freedom.” When Taiwan’s economic performance is less satisfactory and China’s economy appears stronger, legislators tend to emphasize the economic benefits of engagement with China. Moreover, legislators elected from districts more dependent on agriculture and fisheries tend to emphasize China’s economic opportunities.
