比较优势理论自提出以来,一直是国际贸易的理论与实践基础,但是现有理论却受到比较优势陷阱、竞争优势等实证与理论的挑战。笔者认为这种现状是由传统比较优势理论对要素分析的限制所致。本文认为应该从全要素的角度分析比较优势的来源。 The theory of comparative advantage has been the theoretical and practical basis of international trade since it was proposed, but the existing theories are challenged by the evidence-based theory and the traps of comparative advantages. I believe that this situation is due to the traditional comparative advantage theory of the limitations of factor analysis. This paper argues that the source of comparative advantage should be analyzed from the perspective of total factor.
