Study On The Intensity Of Urban Economic Linkages And Its Influencing Factors Between Ningbo And The Yangtze River Economic Belt

As the country puts forward regional coordinated development strategies such as "the Yangtze River Economic Belt along the Yangtze River" and the "Yangtze River Economic Belt",the development of cities has already broken the geographical restriction.The development of the cities is not isolated in a certain region.In order to obtain opportunities and achieve sustainable development,Must be strengthened with other cities of mutual contact,realize complementary advantages,benefit sharing.It is of great significance to study the intensity of economic ties between cities and to judge the focal points of economic ties between cities.This will help the cities to realize economic cooperation and division of labor and promote the coordinated and sustainable development of cities.In this paper,39 cities along the Yangtze River economic belt research object,a combination of regional economics,economic geography,spatial interaction and other theoretical knowledge to build a model of gravity on the Ningbo and other cities along the intensity of economic linkages were measured,The relationship between the intensity of the factors affecting the size of the analysis.The main contents are as follows:(1)The background and significance of the study and the current research results at home and abroad are briefly described,and the innovation of this paper is put forward.(2)The development status of 39 cities along Yangtze River Economic Zone,(3)is the use of gravity model of Ningbo and the other 38 cities along the economic link between the intensity of a measurement,analysis of the economic linkages between the city and the city's economic linkages,Which cities in Ningbo and economic ties between the more closely,where themain economic ties,which can Ningbo's future urban development strategies and economic layout to provide good support,(4)is for the strength of economic ties measured results,the use of The paper analyzes the factors that affect the strength of economic ties,and uses the pearson correlation test to monitor the correlation of the factors to the intensity of economic ties.It also analyzes the factors that influence the relationship between Ningbo and the The strength of the city's economic ties is most affected.Based on the above analysis,three conclusions are drawn:(1)The urban economic linkages between Ningbo and the Yangtze River Delta are the most intensive,and the urban economic ties with the central and western regions are weak,and the urban belt in Anhui and Anhui The economic links between Nanchang and Jiujiang in Jiangxi Province are comparatively close,and the economic ties between Guiyang,Chongqing and Chengdu are close in the western areas.(2)From the four aspects of function,accessibility,complementarity and regional policy(3)There is a significant correlation between economic link intensity and information accessibility,functionality,road accessibility,and railway accessibility,as well as the relationship between railway linkages and railways Accessibility,road accessibility and information accessibilityFinally,according to the results of the analysis,this paper puts forward four countermeasures and suggestions: improving imbalance of regional economic development,constructing three-dimensional integrated communication channel,strengthening complementary economic links and promoting the positive effect of policy environment.
