本文嘗試彙整國際關係學界對「折衷主義」的研究成果，釐清該途徑在國際關係研究中的主要發展，以符合本文探索跨理論分析架構之目的，俾對中東歐區域安全提出更為宏觀而全面性的分析。由於國內對於「折衷主義」的認識尚屬初步發展階段，透過本文對理論整合應用的討論與中東歐區域安全的個案分析，當有助於研究者瞭解何謂折衷主義？學界對該研究途徑存在何種爭辯？其內在邏輯與實際應用又為何？進而熟悉此一研究途徑的應用方式，及其可能出現的若干潛在問題。

This thesis aims to discuss regional security in Central-Eastern Europe (CEE) and analysis its development and challenge. In order to fit in with the purpose exploring approach of trans-theoretical analysis, this thesis aims to collect literatures about Analytical Eclecticism and apply it to CCE case study for comprehensive observation. Given the preliminary stage domestic research community has been, we expect to provide the more understanding, debating, and applying of Analytical Eclecticism in IR field.
