要素异质性与贸易动态收益的收敛

Factor Heterogeneity and the Convergence of the Dynamic Gains of Trade

本文从要素异质性的视角研究发展中国家的贸易收益如何向发达国家收敛。本文的创新在于考察要素之间质的差异,提出要素异质性概念,利用一个简单的贸易动态收益模型,分析了充裕要素为异质要素的国家间贸易的收益差异。结果发现,要素异质性可以解释更多的贸易模式,当发展中国家的充裕要素升级为与发达国家充裕要素同质的要素时,其动态贸易收益将收敛于发达国家。本文的研究在贸易模式及贸易效应方面都扩展了要素禀赋理论。

This paper studies how the gains of trade in developing countries converge to those in developed countries from the perspective of factor heterogeneity.We develop a new concept of factor heterogeneity and construct a dynamic model to analyze the differences in gains of trade between countries endowed with different kinds of factors.Our research demonstrates that as the structure of factor endowments in a developing country converges to that in a developed country,the developing country will achieve the convergence of its gains of trade.Thus,our study extends the neo-classical trade theory in the field of the patterns and dynamic effects of trade.
