國際政治經濟學自一九七〇年代發展以來，關於該新興學科的定位一直 存在著爭議。一般認為國際政治經濟學是一門國際關係學與政治經濟學的交 叉綜合學科，主要是探討國際政治與國際經濟、國際政治與國内經濟、以及 國際經濟與國内政治之間的互動關係。這些關係是如何互動以及該如何互 動，基本上有三大研究途徑，包括經濟民族主義、經濟自由主義與馬克思主 義，的分析觀點，本文主要研究目的就是試圖比較此三大學派各自從國際關 係學與政治經濟學汲取哪些思想與研究方法。經由這樣的整理思考，不僅可 以了解三大學派觀點的異同，也可以幫助釐清國際政治經濟學與國際關係學 或政治經濟學之間的競合與差異所在。最後本文建議，將近來國家學成果帶 入國際政治經濟學的研究當中，對於這門新學科的掌握是會有幫助的。

Since 1970s the development of International Political Economy (IPE) has caused some debates about the essence of this new discipline. In general, the research of IPE is to combine the work of International Relations with Political Economy, and to investigate interactions between international politics and international economy, international politics and domestic economy, and international economy and domestic politics. Basically, there are three major perspectives —Economic Nationalism, Economic Liberalism, and Marxism—on studying these interactions. The main purpose of this article is to compare how different perspective has absorbed concept or research method from International Relations or Political Economy respectively. Through this comparative study we may distinguish differences or similarities among the IPE, International Relations, and Political Economy. In the end of this study, the author suggests that the theory of state may help us better understanding on the International Political Economy.
