本文自兩岸經貿互動的衝擊入手，藉此對臺灣形成中的「政治版圖」，提出初步考察。依據本文作者所見，臺灣地區的四大地理區塊 (即北、中、南、東四部) ，由於其經濟結構差異，將對「是否擴大兩岸經貿交流」問題，表現出明顯有別的政治立場，吾人乃可據此分劃「泛綠」，「泛藍」各自之政治版圖。為有系統的探討上述主題，本文將分為以下五部分。在首節中，作者將揭示本研究的主題及目的。其次，作者將介紹所謂「經濟區塊」的分析角度。緊隨其後的第三節，將應用此架構於「兩岸經貿」議題之分析。在該節中，作者將「兩岸經貿」對臺灣區域經濟之衝擊，歸納為四項假說。其後的第四節，作者將對前述假說進行經驗檢證，並討論其結果。在本文末節之結論中，作者將就現實與理論層面，探討此「經濟區塊」架構，是否適用於「兩岸經貿」議題的分析。

　　　　　This paper claims that economic interaction across the Taiwan Strait may contribute to the formation of "political blocs"(regions' affiliation with specific political parties) in Taiwan. We argue that northern Taiwan benefits most from cross-strait economic interactions and as a result favors a KMT- PFP, alliance, especially since the latter supports deregulating trade with and investment in China. For a similar reason, southern Taiwan turns to DPP. In contrast with the north and south, Taiwan's central and eastern region tends to be more neutral in party preference, since they do not benefit as directly from transactions with the Mainland. This paper argues that regional political blocs take shape following regionalized economic interests.
