贸易增长的二元边际研究文献综述

贸易的二元边际成为研究当今贸易增长的新源泉,对贸易增长进行集约边际和扩展边际的分解,有利于更好地理解贸易增长的性质。从贸易增长二元边际的界定、二元边际的理论基础、二元边际对贸易扩张的贡献程度以及二元边际的影响因素四个方面对现有的代表性文献进行归纳和评述,指出现有研究的不足及今后的研究发展方向。

Trade dual-margin becomes a new source of today’s trade growth.It’s better to understand the nature of trade growth by decomposing it into intensive margin and extensive margin.This paper summarizes and reviews the existing represent-ative literatures from the perspective of the definition of the dual-margin,the basic theory of the dual-margin,the degree of contribution to the trade growth and its influencing factors.Thus points out the shortage of the existing research and the research direction in the future.
