贸易好处的来源、测度与实现研究--基于“单位产出结构”的比较优势原理

Study on the Source,Measurement and Realization of the Gains From Trade--Principle of Comparative Advantage Based on Unit Output Structure

基于机会成本概念对李嘉图比较优势原理的解释,不能确定贸易前的利益,故准确测度贸易好处存在困难。而基于单位产出结构概念对李嘉图比较优势原理进行解释,可以确定贸易前的利益,阐明贸易好处来源于经济行为者用更多的时间来生产有比较优势的商品。在此基础上,可以进一步阐述贸易好处的测度方法和实现方式。

Based on the concept of opportunity cost,the interpretation of Ricardo’s principle of comparative advantage cannot be applied to determine the pre-trade benefits.Therefore,it is difficult to accurately measure the gains from trade.However,through the perspective of the unit output structure,the pre-trade benefits can be accurately measured,revealing that the gains from trade come from individual agency devoting more time to produce goods with comparative advantage.On this basis,the measurement and realization of the gains from trade are further illustrated.
