本研究主要以新古典現實主義的研究途徑，檢視跨太平洋夥伴關係(TPP)倡議以來，日本民主黨與自由民主黨在國內與國際面向所面臨到的局勢，以此分析對政策發展的影響，並提供合適的解釋，來說明政策轉變的原因。本論文的主要研究步驟如下:首先是理論的部分，針對國際關係主要學派有關外交政策的論點進行辯證;其次，則是簡要說明 TPP 的形成背景與日本相關政策的推動;復次，進一步說明日本歷任內閣對於 TPP 的立場，並討論面臨的課題;最後，再以理論連結決策過程當中..

This paper attempts to analyze domestic and international situations faced by the Democratic Party(DP)and the Liberal Democratic Party (LDP)since the TPP was proposed from the neoclassical realism approach. The purpose of this paper is to analyze policy development impacts and explain the necessity of policy changes. This paper will focus on (1) critical thinking of foreign policy from different major international relations theories, (2) backgrounds of TPP development ..

本研究認為，為更加切合國際關係的現實，必須從全球與區域層次重新修正國際關係理論的結構現實主義。攻勢現實主義雖然初步涉及全球-區域層次，提出區域霸權概念，不過由於該理論在本體論、體系結構理論和區域層次上的論述缺失，最終還是受到守勢現實主義框架的限制。本文因此以Barry Buzan和Richard Little的「互動能力」概念作為物質性建構的關鍵因素，使攻勢現實主義的本體論和體系結構觀得以動態化，並填補該理論在區域層次上的不足。本文也將區域層次作為全球層次的..

This study argues that in order to fit into international relations, it is neces- sary to establish a global-regional level of structural realism. Despite the con- tribution of Offensive Realism by bringing in regional hegemony to the global level, it challenges the traditional assumption of structural realism, which is the constant anarchy underlies the international system. However, due to the defi- ciency of Offensive Realism in explaining ontology, system-structure theory, as well as the regional level, it ultimately retu..
