為了提供一個充分的分析架構，學者們運用許多不同的國際關係理論模式來描述、解釋並予測兩岸關係的變化。其中「戰略三角」途徑不但本身邏輯結構嚴謹完備，又能同時顧及中大陸、臺灣以及美國這三個主要類為者之間的互動關係。因此本文在此引介此一理論模式，並對其內容加以補充，再以柯林頓總統時期的美「中」臺三角關係作為例證，以說明構成戰略三角的三個行為者彼此間的關係，在不考慮其內部因素影響的前提之下，將會朝向友好而非衝突的方向前進。

　　　　　To provide a sufficient analysis structure, scholars apply various international relation theories or models to describe, explain and predict the evolution of the cross-strait relation. The "strategic triangle" approach is not only strict in logic structure but also covers the interaction among the three main actors namely Mainland China, Taiwan and the United States. The approach, supplemented by the real-term relation among the three player in the Clinton period, is used in my paper to demonstrate that, without considering internal factors, their relation will move in the direction of amicability rather than conflict.
