Abstract:

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
