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..

國際關係理論逐漸呈現以理論綜合的方式進行國際關係研究，國際規範研究是其中的重要議題之一，本文嘗試從國際規範的生命週期開始，運用「國際規範社群下的策略行動」(strategic actions in a international norm community)，以理性主義(策略行為)與建構主義(規範行為)理論綜合的策略與研究途徑分析美國「防止擴散安全提議」，探索此國際規範的興起、擴展、內化與侵蝕階段時期中，不同國家的行為動機，藉以呈現說明理論綜合能提供不同面向的相互補充解釋。

The international norm is one of the major topics in international relations research, of which synthesized approach is gradually becoming a trend. This paper attempts to adopt Frank Schimmelfennig's approach- the strategic actions in an international norm community- to synthesize the theories of rationalism and constructivism in the international norm circle. As the case, the Proliferation Security Initiative will be analyzed through different phases of emergence of the life circle-cascade, diffusion, internalization, and erosion- to u..
