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。 Based on the improved trade gravity model, this paper empirically analyzes the data of Liaoning Province from 1990 to 2011. It is found that Liaoning’s cargo turnover and the size of its trading partners’ countries and regions have a positive effect on the growth of trade volume. However, the mileage of the logistics network hinders the growth of trade volume. Therefore, Liaoning should vigorously improve the efficiency of the logistics system, increase the turnover of goods, and promote trade with countries with different income levels and population sizes.
