李嘉图比较优势理论只是以两种产品两国贸易为实例,给多种产品或多个国家贸易的比较禀赋优势说留下思索空间。反对比较优势学说的人们试图给出反例,并认为比较禀赋优势说已被推翻。本文指出一些所谓的“反例”并不能称其为反例,新贸易理论也并不与比较禀赋优势说相悖,比较优势说仍然有其生命力。 The Ricardian theory of comparative advantage merely takes the trade between the two products as an example, leaving room for thinking for the comparative endowment advantage of multiple products or countries’ trade. People who oppose the doctrine of comparative advantage tried to give counterexamples and argued that the comparative advantage of endowments had been overthrown. This article points out that some so-called “counterexamples” can not be called counterexamples. The new trade theory also does not contradict the comparative advantage, and the comparative advantage says it still has its vitality.
