柔性平衡理論以不同於傳統平衡論的觀點解讀國家行為與互動，其認為國家在威脅不明或與他國利益相連等情況下，將透過迂迴隱晦的方式進行平衡。該理論近年來在國際關係學界中漸受關注，研究者們不僅運用其解讀現實案例，也對理論內涵提出許多評述與論辯。本文在回顧既有論著的基礎上探討該理論之內容並檢視各類平衡策略形態，以期呈現柔性平衡理論當前的整體發展狀況，並釐清其內容中的爭議處，以推動後續研究的進一步深化。  

The theory of “soft balancing” deals with the actions and interactions among states that is different from traditional balancing theories. The former features a belief that states achieve balances among themselves in indirect and covert ways under uncertain threats and interests pegged with other states. During the past few years, the theory of soft balancing has gradually gained prominence in academic circles of international relations. Researchers not only apply the theory while interpreting actual cases, but al..

有關於層次分析(levels-of-analysis)的研究早於第二次世界大戰以來即受到西方學者相當之注重，但國內相關之研究仍未重視層次分析之研究途徑，亦很少有研究著作涉及層次分析之研究架構。近年來隨著「建構主義」 在國際關係理論上愈受重視，開展相互主觀、研究「結構/體系」與「單元 /能動者」之動態互動關係，並提及跨層分析的重要性，可惜建構主義學者亦未能將層次分析之相關理論做系統性之整理或推導成分析模型。針對此，本文將傳統國際關係理論及建構主義涉及層次分析的..

Levels-of-analysis has been one of most important IR theory in the West since World War II, but still waiting to be explored in Taiwan. With the rises of constructivism emphasizing the concept of intersubjectivity, exploring the relations between structure and agency, and reverting the significance of cross-levels analysis, researchers are forced to recall levels-of-analysis approach. However, there is still a pity that constructivism did not offer a modeling analytical framework for the studies of levels-of-analysis. Therefo..
