2014 年 2 月爆發的烏克蘭危機是歐洲當前最嚴肅的區域安全挑戰，這不僅是因為烏克蘭危機使得歐洲再度出現區域衝突情勢，同時也因列強介入而使得地緣競爭強度漸趨激烈。學界多探討烏克蘭危機及其背後的歐洲地緣競爭意涵，然較少從烏克蘭內部安全策略選擇的角度分析，本文嘗試補充此等觀點，從內部因素出發，分析烏克蘭內部政治如何影響區域危機的發生。 本文認為:第一，烏克蘭受制於強權競爭，使烏克蘭與其他中間地帶國家，都必須在左右強權互動格局下進行回應與策..

Ukraine is situated strategically between EU and Russia. The outbreak of the Euromaidan Revolution(February 2014)designates the advent of severe geopolitical competition in the European continent. Though it is crucial to understand this competition through the lens of great power rivalry, small and medium countries that exert certain leverages between great powers also warrant our attention. We argue that the domestic approach is suitable to explain the transformation of Ukraine’s security choices. We first develop an a..

新現實主義針對外部平衡提出了許多的模型，但卻未能說明國家為何，以及如何在不同類型的內部平衡間進行選擇，以回應外在的壓力。要解釋一國在軍事政策上的變化，必須以一種結合體系與單元雙層次變數的理論進行分析，而這種理論的基礎即是目前方興未艾的新古典現實主義。不過，新古典現實主義雖注意到了單元層次的重要性，卻仍忽略了國家行為邏輯的雙重性，亦即，國家除了權衡利害關係(後果性邏輯)以做出決策外，在此過程中，也會受到文化因素(適當性邏輯)的影響。本研究即是希望能夠透過理論綜..

There are many models of external balancing based on neo-realism. Nevertheless, not all can interpret why and how states choose among different types of internal balancing strategies to response the extrinsic stress. To understand the change of a state’s military policy, neoclassical realism integrates the system-level and unit-level variables. However, it still ignores the dual nature of the logic of state’s action, namely, besides interest, the influence of culture. Hence, a new “secure arming” model..
