Research On The Simulation Of The Coordinated Development Between The Central Plains Urban Agglomeration And The Surrounding Regional Economy

Since the reform and opening up,The state has gradually developed four development strategies,namely,"the great development of the western region","the rise of the east","the east takes the lead in development" and "the revitalization of the northeast".And in the new normal,The government has slowly put forward regional development strategies such as "coordinated development of Beijing,tianjin and hebei" and "Yangtze river economic belt".As a result,the degree of mutual penetration,mutual influence and interdependence between each city gradually deepened.In the context of the new pattern of regional development and the need for a new type of urbanization,In view of such problems as obvious differences in urban agglomeration development and insufficient coordination,The internal coordinated development of urban agglomeration has practical research significance.Compared with other research literature,There is a lot of internal coordination among the central plains,beijing-tianjin-hebei and other city clusters.However,there are few collaborative studies on the central plains and surrounding areas.And most analysis starts from qualitative Angle.According to the above background,Based on the theories of urban agglomeration,system,coordinated development and system dynamics,this paper makes a basic analysis.Make a truthful analysis of the progress and trend of economic integration in central China and surrounding regions.The thesis is mainly carried out from the following parts:(1)By means of economic gravity model and social network analysis,the node connection network,spatial "small group" distribution state,core-to-edge structure and industrial convergence in the research area are analyzed.(2)On the basis of synergetics and entropy theory,Comparing multiple models of synergetic degree,It is found that the synergy degree model of composite system is most suitable for this study.This model is applied to establish the index system of population-sci-technology-economy evaluation in the research area.To truly study the evolution trend of the development degree and synergy degree of the central plains and surrounding areas;(3)According to the operation mechanism of the economic system in the region,Using the theory and method of system dynamics,To build the SD model of population,technology and economy,To simulate the basic behavior of the system,orecast the coordinated development trend of the system after 2016.The conclusion is as follows:(1)The industrial linkage network of the Central Plains urban agglomeration is getting increasingly mature,but the development of various industries is not balanced,and the relative output efficiency is low;(2)The overall network structure presents a typical but gradually weakening single-core form,while appearing the multi-center characteristics,which shows the trend of “flattening”development;(3)The networks of various industries in the Central Plains urban agglomeration have developed a relatively stable morphology of cohesive subgroups and shown different morphological characteristics;(4)The network structure of each industry has high correlationwith each other,obvious characteristics of industrialintegration,and convergence in regional economic industrial structure;(5)From 2006 to 2016,the overall regional synergetic degree in the economic,population and science and technology subsystems gradually increased from 2006 to2016.Moreover,the synergetic degree of regions such as the Yangtze river delta city cluster and the city cluster in the middle reaches of the Yangtze river is significantly higher than that of the taiyuan city cluster and the central plains city cluster.According to the system dynamics model,the collaborative development in the research area is gradually optimized.
