区域贸易投资协调发展的空间数据分析——来自长三角25个城市的经验证据

An Exploratory Spatial Data Analysis of Regional Trade and Investment Coordinative Development——Evidence from 25 Cities of the Yangtze River Delta Region

运用主成分评价方法构建了八个区域贸易投资协调度评价指标,测算得出长三角地区间贸易投资处于由不协调向协调发展的过程,但协调发展并不稳定。继而运用经济增长收敛理论,从贸易投资的视角对长三角地区25个城市的经济差异性进行了深入检验,实证检验结论为:长三角区域间贸易投资协调合作行为有助于缩小地区经济差异。基于此,从长三角地区产业、政府、企业三方面提出了区域贸易投资协调发展的对策建议。

In this paper,we use the principal components analysis to establish 8 indexes about the coordinative development degree of trade and investment in the Yangtze River Delta region.We find a tendency that trade and investment development in the Yangtze River Delta region is changing from in-coordination to coordination but the process is not steady.Based on the convergence theory within the economic growth theory,we make an empirical research on the economic differences between 25 cities in the Yangtze River Delta region from the perspectives of trade and investment.The empirical result shows there is a conditional convergence in the economy of the Yangtze Rive Delta region.And regional trade and investment coordinative development can help to narrow regional economic disparity.At last we put forward some suggestions on the harmonious development of trade and investment among regions from aspect of industries,government and entripises.
