国际贸易的“相对价格不等式”与“广义比较优势”

The Inequality of Relativity Price and the Generalized Comparative Advantage in the International Trade

本文在哈伯勒运用比较成本解释比较优势原理的基础上,提出国际贸易的"相对价格不等式"。经过要素禀赋理论、产品生命周期理论和规模优势理论对该不等式的检验,本文得出该不等式在经典的国际贸易理论中是成立的结论。在此基础上,本文提出"广义比较优势"概念,并指出其不仅有重要的理论研究意义,而且在当今全球金融危机冲击和影响下,有着重要的理论现实意义。

Harberler explained the theory of comparative advantage applying comparative cost in 1936. Based on it, this paper has put forward the Inequality of Relativity Price in the international trade. Through the examination of theories of factor endowment, product life cycle and economies of scale respectively, this paper has drawn the conclusion that the inequality is founded in the classical theories of the international trade. Then, this paper has brought forward the new concept of generalized comparative advantage, and pointed out that it has the important theoretical and practical meanings of the international trade, especially under the condition of the global financial crisis.
