兩岸關係雖然時有衝突情事阻礙雙邊合作關係進展，但在一段時間的 停滯、甚至倒退後，總能再造新一波更高層次的合作與交流，並向兩岸統 合向前跨出一大步。此一「正、反、合」的辯證性，愈發引起兩岸關係學 者的嚴正關注，並嘗試以此思考突破兩岸關係發展現況的可能性。進而言 之，若以辯證功能主義（dialectical functionalism)觀察1949年以來的兩岸 關係發展，則兩岸關係發展脈絡多大程度符合該理論之命題？而對照近期 服貿爭議以來兩岸關係的停滯現象，是否正意謂著新一波統合契機正在蘊 釀而生？本文首先將從國際關係功能主義演進切入，釐清辯證功能主義的 基本主張與分析重點；其次，回顧兩岸分治迄今的政經發展脈絡，並從辯 證功能主義的視角，解釋兩岸統合的進展、停滯與突破；最後以近期兩岸 服貿爭議為探討個案，分析該事件之正、負面影響。

In terms of Cross-Strait Relationship, some conflict situations had hampered bilateral cooperative relations and this “stop”，even backward, phase may last for a while, yet another “go” phase will emerge and promote a new wave of cooperation and exchange. These “thesis, anti-thesis, synthesis” dialectical features have raised academic concerns and incurred the debates about the applicability of this prototype. Furthermore, if we look back the Cross-Strait relation since 1949, how can we be sure that the evolutionary path has followed the prediction of dialectical functionalism? The controversies of Cross-Strait Trade Service Agreement resulted in the stagnation of bilateral relations development. Would this situation stimulate an opportunity for a new wave of cooperation between two sides? This paper first focuses on the theory of dialectical functionalism, and tries to clarify its main arguments and the analytical concepts; then analyzes the controversies of Trade Service Agreement and the possible impacts on the bilateral relations between Taiwan and Mainland China. Whether or not this situation would be inclined to positive developments remains to be seen.
