90年代後,中國開始揚棄毛澤東主政期間所抱持的「早晚要打第三次世界大戰」的對抗式國際關係觀點,對外關係上轉向和平、合作、互賴的理念,並開始融入既成的國際建制中,而最凸顯的案例莫如中國加入亞洲區域整合的相關作為。中國是基於什麼樣的理由加入亞洲整合?對於國際體制抱著什麼樣的態度?是否如新自由制度主義所論述,真誠擁抱制度、接受制度的制約與規範?本文透過分析中國學者的觀點與中國參與區域整合的相關作為,並以新自由制度主義的論點加以交叉比對後發現,不論是大陸學者論點或者大陸的實際外交作為,從目前觀之,90年代後,中國大陸的言行大致符合制度主義的理念:追求利益共享、互惠,建立制度形成互動規範。本文認為,這不僅驗證了制度主義在分析中國外交作為上的理論實用性,也提供了對中國未來外交作為研判與分析的可靠途徑。 In the 1990s, the PRC began to renounce the conflict point of international relations held in Mao Zedong period, turned to peace, cooperation and interdependence concept and began to integrate into the international institutions. The most specific case is the PRC join the Asian regional integration, for example, the ASEAN–China Free Trade Area. Why does the PRC join the Asian integration? What kind of attitude does the PRC hold for international institutions? Does the PRC sincerely embrace the international regime, and accept the constraints and norms of the international regime like the neo-liberal institutionalism has discussed?This paper first focus on the views of the PRC’s scholars and what the PRC has done in the regional integration. Second, this paper reviews the PRC’s cognition of Asian regional integration and its performance with the arguments of the neo-liberal institutionalism. After research we find, from 1990, the PRC does practice what she preaches and follow the ideas of neo-liberal institutionalism: pursuit of shared interests, reciprocity, and to establish international institutions or regimes. We can say the PRC’s diplomatic model in Asian regional integration is the neo-liberal institutionalism style.
