贸易引力模型的理论研究进展及应用中存在的问题

Development of the Theoretical Study on Trade Gravity Model and Issues in Its Application

引力模型在分析国际贸易现象时具有较强的解释力,但却因缺少经济理论基础而常被责难,同时在应用中也存在一些问题。本文以引力模型的理论基础是建立在一般经济理论还是国际贸易理论上为线索,首先介绍了西方贸易引力模型的理论基础研究进展,并指出其研究不足;然后对贸易引力模型的表达形式、距离系数的解释、动态与静态模型的选择以及不适用的贸易现象等应用中存在的问题进行述评;最后指出贸易引力模型在理论研究中的发展方向和应用中需要解决的问题。

Gravity model is authoritative in analyzing international trade but it is often criticized for its lack of theoretical foundation.At the same time,there are some problems in its application.Using the clue whether the theoretical foundation of gravity model is general economic theory or international trade theory,the author firstly introduces the researches in the development of western trade gravity model,points out the weakness in the researches.Secondly,the author reviews the issues in the expression of t...
