國際系統的理論化是國際關係理論發展的關鍵階段之一，甚至有學者認為國際關係理論研究如同是(國際)系統理論化的傳統。國際關係學者從 1950、60 年代開始進行國際系統的理論化，嘗試建立科學研究的國際系統理論，不同的學者都嘗試藉由其他學科學者的系統理論(systems theory)提出不同的國際系統理論化途徑。國際關係歷史社會學學者歷經三階段的國際系統理論化途徑，第一階段引述歷史社會學學者的國際系統觀點，作為其國際系統理論化及批判新現實主義國際系統理論化的主張..

Theorization of the “international systems” is a critical stage in the development of International Relations Theory(IRT). Some IR scholars even thought that IRT is a tradition of(international)systems-theorization. Since the 1950s and 1960s, IR scholars began to theorize the “international systems” and build a scientific study on international systems theories. Many scholars tried to propose approaches in theorizing the “international systems” through system theories from other disciplines..

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..
