Research On The Coupling Relationship Between Industrial Agglomeration And Urban-Rural Spatial Pattern In The Yangtze River Delta

The Yangtze River Delta covers three provinces and one city in geographical space,covers a large area,and has a large economic aggregate.For a long time,the advantages of the Yangtze River Delta in terms of capital,talents,location,and corporate policies have attracted domestic and foreign resources and factors to flow into the region.According to the "Outline of the Yangtze River Delta Regional Integration Development Plan" issued by the State Council of the Communist Party of China on December 1,2019,the planning scope is centered on Shanghai,relying on the status of Shanghai's financial center and international influence,with 26 cities as the central area,radiating The surrounding urban and rural areas promote the development of the Yangtze River Delta towards high quality and high standards.At present,the division of labor within the Yangtze River Delta region is not clear.The positioning of industrial agglomeration parks is similar,with serious homogeneity;and competition among regions is relatively large,and the phenomenon of competition for resources and factors exists objectively.Promoting regional coordinated development by restructuring the spatial pattern has become an inevitable choice to use resources and resolve contradictions.The overall value brought by the coordinated and coordinated development of the industrial agglomeration of the Yangtze River Delta and the urban-rural spatial pattern will continue to expand based on the optimization of the spatial pattern.The road is clear,the key is how to go better,better and more efficiently? Based on the analysis of the Yangtze River Delta region,this paper explores the evolution mechanism and coupling relationship between industrial agglomeration and the spatial pattern of urban and rural areas.This paper summarizes the relevant theories and literature reviews of industrial agglomeration and urban-rural spatial pattern,and summarizes the changes in the relationship between the two subsystems and the mechanism of coupling and coordination.First of all,it analyzes the development status and existing problems of the industrial agglomeration and the urban-rural spatial pattern in the Yangtze River Delta.It is found that the current lack of unified administrative power in the Yangtze River Delta region,the development contradictions force the region to transform,and the development gap between cities is significant.Motivation factors and mechanism of agglomeration and urban-rural spatial pattern.Secondly,conduct empirical analysis on 27 central cities from 1995 to 2018,and use the Global Moran's I index in ESDA spatial autocorrelation to analyze the overall distribution of industrial agglomeration and urban-rural spatial pattern in the study area,and then use its local spatial autocorrelation The Moran scatter plot and LISA chart show the significance level of the geographical unit's spatial correlation with the surrounding area.Finally,the collected data is used to construct an index evaluation system for the industrial agglomeration and urban-rural spatial pattern of the Yangtze River Delta region.The ArcGIS softwaremapping shows the changes in the coupling and coordination of the study area during the study period.It is concluded that the Yangtze River Delta faces many challenges as the main space carrier to cope with the new normal of the economy,and the coordinated development of regional space has become an inevitable trend.From 1995 to 2018,the coupling relationship between the industrial agglomeration of the Yangtze River Delta and the urban-rural spatial pattern has continued to deepen.From 1995,the geographical unit was mostly in a moderately declining and declining phase to 2018,when the geographical unit was mostly in the primary coordinated development stage.Shanghai and Suzhou It has taken the lead to enter a stage of well-coordinated development.The degree of coupling between the industrial agglomeration in the regional space and the urban-rural spatial pattern has shown a significant upward trend;it is visually represented as a "Z"-shaped expansion on the map,and the recent development will be expressed as " "Zigzag" space structure,the Yangtze River Delta region has initially shown a multi-centric network development model.
