劳动供给剩余条件下的比较优势理论质疑

比较优势理论自提出以来,一直是世界各国进行国际贸易,获取经济利益,推行贸易自由化的核心理论,主流经济学将比较优势理论作为各国参与世界分工的理论基础。但是现实中一国在存在劳动力供给剩余的条件下按照比较优势理论却未取得经济的进步与增长,从而引发对该理论有效性的争论。本文试图在分析劳动供给剩余条件下比较优势理论对一国国际贸易的影响,提出在劳动供给剩余条件下,比较优势理论与一定的保护贸易存在某种内在的联系。

An Inquiry to the Theory of Comparative Advantage under the Surplus of Labor-supply

As the theoretical foundation of the free trade, the theory of c omparative advantage has been the key theory that every country in the world has carried on in international trade to get economic benefits all the time since i t had been proposed. And trade liberalization becomes the theme of economic deve lopment. But under the circumstances that one country exists labor-supply surplu s condition, it has violated the assumption prerequisite of the theory of compar ative advantage, thus causes the dispute of this theory validity. This paper att empts to analyze the effects of comparative advantage theory on one country's fo reign trade under the labor-supply surplus condition, and proposes that the theo ry of comparative advantage has a certain inherent connection with certain prote ctive trade under the surplus condition of labor-supply.
