附加环境因素:传统比较优势理论的扩展

在李嘉圈模型中，若将环境成本用追加的劳动投入来衡量。可以发现，环境成本的引入将修正传统的比较优势格局。在H-O模型中耐加环境因素，亦即假定环境作为一种生产要搴而起作用。则所形成的比较优势将建立在包含环境要素真实价格的基础之上。本文最后指出，环境要素的真实价格与现实价格的脱离，使“显示的比较优势”有可能与真实的比较优势发生偏离。从而损害效率与公平。

EXTENSION OF COMPARATIVE ADVANTAGE THEORY, WITH THE FACTOR OF ENVIRONMENT ATTACHED

In Ricardian Model, if we measure the environmental cost with the additional labor cost, we will find that the introduction of environmental technology and environmental cost will correct the traditional pattern of comparative advantage. Embedding the factor of environment in H-O Model, that is to say, assuming environment to be a kind of productive factor, the generated comparative advantage will be based on various prices including environmental actual price. In the end, the paper points out that the divorce of real prices of environment from actual prices of environment will make the manifested comparative advantage separated from the true comparative advantage, and then destroy efficiency and equity.
