Strength And Structure Analysis Of Spatial Economic Linkages Between Wanjiang Urban Belt And The Yangtze River Delta Central Cities

2010 State Council formally approved the "Wanjiang City to undertake industrial transfer demonstration zone planning." In 2016 the State Council adopted the "Yangtze River Delta Urban Agglomeration Development Plan",and Anhui Province,Hefei,Wuhu,Maanshan,Tongling,Anqing,Chuzhou,Chizhou,Xuancheng 8 cities into the plan.Thus,both in the Anhui provincial level or in the Yangtze River Delta city group,Wanjiang urban belt status has been greatly improved.Wanjiang urban belt as the most active areas of Anhui Province,in the history of the Yangtze River Delta and the central city has a more close economic exchanges.However,compared with the provinces of Jiangsu and Zhejiang provinces,the spatial economic link between the urban area of Wanjiang and the central city of the Yangtze River Delta is relatively weak,and there is a big difference between different cities.In order to make full use of the central city of Yangtze River Delta to carry out the role of radiation in Wanjiang urban belt,it is necessary to further strengthen the spatial economic link between Wanjiang urban belt and central city of Yangtze River Delta and accelerate the integration of Wanjiang urban belt into Yangtze River Delta urban agglomeration.Based on the characteristics of the existing spatial economic ties in the region,the theory of regional economics,space economics,statistics and other disciplines,this paper uses the gravitational model as the basis of the analysis,combined with the Yangtze River Delta city center and the Yangtze River Delta city as the research object The quantitative analysis of the center function intensity index,the measurement model of the regional spatial economic link,the spatial economic connection of the study area,and the qualitative analysis and dynamic analysis and comparison,reveal the Wanjiang city belt and the Yangtze River Delta The Main Direction and Mechanism of Spatial Economic Linkage Strength in Central Cities.It is found that there is a close spatial economic link between the cities and the central cities of the Yangtze River Delta,and the strength of the links is mainly reflected in the size of the economic links between them.The main factors influencing the spatial economic linkages are the distance,the population,the regional GDP,the area of the built area,the education level of the population and the number of employees in the industry.The influence of the distance is the most prominent.The results show that the economic link between Wanjiang urban belt and central city of Yangtze River Delta is: Nanjing,Shanghai and Hangzhou.Specific to the Wanjiang urban with the city,and the Yangtze River Delta city center of the spatial economic link is uneven.In view of the status quo of the spatial economic link between the urban belt of Wanjiang and the central city of Yangtze River Delta,it should strengthen the industrial undertaking ability by seizing the opportunity of industrial transfer.Actively participate in regional division of labor,the depth of integration into the Yangtze River Delta.Build modern transportation network,strengthen interconnection construction.Strengthen the comprehensive strength of Wanjiang city,promote the development of economic complementarity and other measures to promote the Wanjiang urban belt to accelerate integration into the Yangtze River Delta urban agglomeration,so as to further close the spatial economic link between each other.
