基于引力模型的物流对辽宁省对外贸易的实证分析

An Empirical Analysis of the Impact of Logistics on International Trade in Liaoning Province——Based on Revising Trade Gravity Model

文章根据改进的贸易引力模型,对辽宁1990-2011年的数据进行实证了分析。发现辽宁货物周转量和贸易伙伴国(地区)的人口规模对贸易额增长有促进作用,而物流网络里程阻碍贸易额增长。因此,辽宁要大力提高物流体系的效率,增加货物周转量,促进与不同收入水平及人口规模国家(地区)之间的贸易发展。

According to the revising trade gravity model and using the 1990- 2011data of the Liaoning Province,the results are that cargo turnover, population size of trade partner countries(regions)have positive effect; Length of transport routes has negative effect on the trade of Liaoning province. Thus, Liaoning province should improve the efficiency of logistics system greatly to increase cargo turnover, and to promote trade with different income levels and population sized countries (regions).
