在一個以美國為首的後冷戰單極國際體系中，次級強權與美國之間的動態性權力安排，將直接影響單及體系是否得以續存。傳統國際關係理論主張「權力平衡」是維持國際社會與區域安全的穩定要素，但該理論針對的是強權間為維持軍事戰略利益，所採取以軍事力量作為手段的平衡關係，對於後冷戰時期美國與其他次級強權的互動，似乎缺乏解釋的效力。在這些次級強權當中，歐洲聯盟扮演一個非常特殊的角色。歐洲與美國同享重要的文化與宗教價值，但在具戰略意義的議題上，兩者的歧見卻益形明顯。歐盟在重大國際議題上與美國的背道而馳，已形成..

In a U.S.-dominated post-Cold War unipolar international system, the possible power shifts between the second-tier great powers and the Americans, such as a systemic balance, will have great impacts on the existence and endurance of the current international system. According to the Realist theses, “balance of power” is a stabilizing factor that contributes to international security and regional stability as the great powers endeavor to prevent concentration of capabilities in one or a few nations through the process of distribu..

國際關係理論是與現實的國際政治高度聯結的，此一現象在當今表現地極為明顯。美國與中國的戰略競爭召喚著能夠掌握與回應現況的國關理論，其中尤以「權力轉移」和「歷史與國關」兩類文獻最具有解釋力與發展性。本文從權力轉移理論的核心論點與適用的範圍條件切入，接著聚焦於此一理論的兩個關鍵變項：權力差距與挑戰者對現狀的滿意程度，並延伸到戰爭的爆發條件與對理論的挑戰，最後是討論崛起國與支配性強權的新興理論框架。在這一部份又分為三個部分：崛起國對支配性強權的策略選擇、支配型強權對於崛起國的策略選擇，和崛起國與..

International relations theories are always closely connected to real world international politics. This connection between theory and reality is particularly pronounced in today’s world. The strategic competition between the US and the PRC stimulates IR theories that can grasp and respond to the international reality. Among those the “Power Transition Theory” and “History and IR approach” are of the greatest explanatory potential. This paper begins with the core arguments and applications of the power transiti..
