本文首先概要介紹東亞區域合作的動能,然後從政治與經濟連結的觀點探討「東協加三」的歷史進程與關鍵內容,輔以對東北亞及東南亞各自與相互間合作發展的觀察。本文再針對東亞各國對區域合作的概念認知、議題領域及政策產出三大面向進行分析。雖然「東協加三」的合作模式提高了東北亞與東南亞之間政經連接的可能性,而且在概念認知與議題領域兩方面都有長足的進步,但在政策產出方面,特別是東北亞的政治矛盾與不協調仍然使得「東協加三」的合作充滿未知的變數。在可預見的將來,「東協加三」機制可能慢慢地推進,並且主要表現在低階政治的領域。美國的態度與中共、日本的回應也是影響東亞區域合作與整合的重點。最後,本文指出「東協加三」理論分析的難題,做為未來研究參考。
This article first introduces the momentums of cooperation in the region of East Asia. From a perspective of political-economic linkage, it explores the history and key components of ”ASEAN plus 3,” and touches various forms of cooperation in North Asia and Southeast Asia, respectively, as well as reciprocal cooperation between these two sub-regions. Then, three major aspects for analysis of East Asian regional cooperation are brought up; they are: conceptual recognition, issue areas, and policy outputs. Despite a higher possibility of linking Northeast Asia and Southeast Asia politically and economically via ”ASEAN plus 3” cooperation, and despite salient progress in conceptual recognition and issue areas, future cooperation among ”ASEAN plus 3” countries is still full of uncertainty because of the intricate policy outputs-Northeast Asian's political paradoxes and lack of coordination in particular. In the foreseeable future, it is likely that the ”ASEAN plus 3” regime will progress slowly, with better achievements in low politics. Besides, America's attitude and the PRC's and Japan's responses will be very influential in regional cooperation in East Asia. In the end this article presents some puzzles for future theoretical analysis research.
