The Studying On The Economic Space Interaction And Development Intergrated Of Wuhan,Changsha And Nanchang

Since the 20th century, with the further development of information technologies and transportation technologies ,the relationship between countries and reagions are more and more osculation, regional economic cooperation has become a world economic development trend. Any regions or countries are impossible to rely on the self-enclosed regional economy while entering the ranks of advanced countries,.So this article based on the development of middle China, taking Wuhan, Changsha and Nanchang as the research objects,using comparative analysis to analyze the level,accumulation and extroversion of the economics. Although the cities of the three have some differences in the overall level ,they have greatly improved in the development level and speed , also become the center of economic development in the provinces, and can influente the peripheral cities . All these provided the premise and the foundation for the three cities affectting mutually.The most important of this text is talking and amending the gravitational mode ,and then using the modle to calculate the strength of the economic space interaction among the three cities.At last I found that the strength of the economic interaction is bigger than other cities in middle China;Then compared with Yangtze River Delta and Pearl River Delta's inter-city. The results also showed that whether in the urban development level, distance or strength of the economic interaction, the three cities in the central city status are similier as Shanghai, Nanjing, Hangzhou and Guangzhou and Shenzhen in the Yangtze River Delta and Pearl River Delta.So the three cities have the foundations of development integrated and the possibility of becoming the engine of the growth of the economic and the fourth pole of the economic development; then, I also introduced the theory of spatial interaction, analysed the base of the three cities developing conformity from transferability,complementarity,interveing opportunity.Last , the text analysed the problem when the three cities developing intergrated will face.and putting forward the according suggestion and measure .
