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..

要探究國際關係建構主義理論的學術貢獻與影響，實有必要回歸到其肇 始之初的系絡，即是 Nicholas Onuf 與 Friedrich Kratochwil 的學術生涯發展之 中，由於 Onuf 和 Kratochwil 所受的國際法與國際關係學術訓練，致使他們 致力於以社會理論連結國際關係理論與國際法。國際關係建構主義理論也就 是肇始於他們兩人的此連結當中，進而逐漸擴展成為國際關係重要的理論或 研究途徑。 本文的主旨在比較分析 Onu..

To explore contributions and influences of constructivism, we should trace back to the career developments of Nicholas Onuf and Friedrich Kratochwil. Due to their trainings of International Law ( IL ) and International Relations(IR), they have focused on linking IR and IL with constructivism as a social theory. Constructivism originated from this linkage and had become an important theory or approach in IR. This article comparatively explores the way of linking IR and IL with social theory(constructivism)in Onuf&rs..
