本文基于区域经济视角,以Eaton和Kortum模型(2002)为基础,采用进出口国家的国内生产总值、绝对优势和比较优势、距离等变量共同构建了一个类似于引力模型的方程。研究表明,贸易国间的距离、共享边界、区域贸易协定PTA影响了双边贸易流量,贸易国的价格、工资、技术水平是影响贸易相对竞争力和开放程度的主要因素,一国可以通过积极参与区域贸易协定、提高技术水平等措施促进贸易发展潜力的提升。
Based on the Eaton and Kortum model (2002), this paper uses the GDP, absolute superiority and comparative advantage of the importing and exporting countries and constructs an equation similar to the gravity model based on the distance variables and other variables. The study shows that the distance between countries of trade, the shared border and the PTA of regional trade agreements have affected bilateral trade flows. The price, wages and technological level of trading nations are the major factors that affect the relative competitiveness and openness of trade. One country can participate in the trade through active participation Regional trade agreements and technological upgrading to promote the potential for trade growth.
