安徽省合肥和芜湖市对外经济联系量与地缘经济关系匹配分析

引入克鲁格曼指数、建成区面积、人口素质权重系数等指标修正了以往的引力模型，利用修正的引力模型确定城市的对外经济联系量。运用欧氏距离法确定城市间的地缘经济关系，并分析其形成的原因。对经济联系量与地缘经济关系进行匹配，并对匹配结果进行原因分析，根据不同的匹配情况提出城市未来发展战略。研究结果显示：(1)合肥市的地缘经济关系互补性大于竞争性，而芜湖是竞争性大于互补性；在地缘经济关系的形成过程中，产品资源向外地的流动能力指标对形成城市间竞争性或互补性的贡献较大。(2)合肥、芜湖两市的地缘经济关系和外联经济联系量的匹配结果都不理想，属于强、较强经济联系量与强、较强互补地缘经济关系的理想匹配结果较少；城市间产业结构的差异性和交通的便捷性成为影响匹配结果的一个原因。增强经济联系量、调整地缘经济战略、优化匹配关系是城市的首要任务

ANALYSIS OF THE MATCH BETWEEN THE INTER-CITY ECONOMIC CONTACT AND GEO-ECONOMICS RELATIONSHIP——TAKE HEFEI AND WUHU FOR EXAMPLE

The paper revises the city gravity model by using the index of Krugman,the area of built-up areas and the coefficient of the population quality.Based on the revised gravity model and distance analysis method of statistics,we analyzes intensities of urban economic contacts and the geo-economic relationships between Hefei(or Wuhu)and other cities in the belt,and makes a matching analysis of the external economic links and geo-economic relations.The paper gives some explanations to these matching results.Then it gives different regional economic development strategy based on the different matching result.The analysis results are as follows.(1) The main geo-economic relationship of Hefei is complementary and Wuhu is competitive.In the forming process of the geo-economic relationship,the flow ability index of product has a significant contribution to the formation of a city competitive or complementary relationship.(2) There is strong competition,overall weak economic ties and unsatisfactory matching relations between the central city and other cities.The industrial structure difference and traffic convenience become a reason influencing the matching result.The main mission for the city in the belt is to change the relations from competition to complementary and strengthen economic ties.
