Research On Urbanization Development Based On Super Network

No economic and social process can create so many opportunities as urbanization,whether it is for the development of industry or the promotion of employment,urbanization can play an important role.Urbanization has become the new economic development engine after China's industrialization,and national economic development has entered a new growth stage driven by industrialization and urbanization.With the deepening of regional trade liberalization,economic integration and informatization,as well as a new round of technological change and the rapid development of knowledge economy,capital,information,personnel and technology and other production factors are constantly flowing,centralized and distributed in the region and among industries.The development of the city has gone beyond its own boundaries,involving geographical space,economic space and behavior subjects and so on.Different attributes and levels of subjects(industries,enterprises and cities,etc.)play different roles in the process of urbanization and through the flow of various factors of production,the relationship between different attribute subjects in and between layers is closer.In this context,it is of great practical significance to clarify the relationship between the main elements of the urbanization development process and to identify the important subjects and their associated combinations that affect the development of urbanization.The development of urbanization on the basis of urban agglomeration is not only the inherent requirement to improve the overall level of urbanization in China,but also the practical choice of accelerating the coordinated development of regional economy.The economic development of urban agglomerations covers economic entities and their relationship structures of different attributes and levels such as industries,enterprises and cities.It can be regarded as the integration of multi-attribute and multi-level subjects such as enterprises and cities based on industrial linkages.Among them,the technical and economic relationship between industries is the internal basis of business exchanges and urban economic and trade exchanges.As the micro-subject of urban economic development,enterprises are the advanced subdivision form of industrial organization network.They rely on the spatial agglomeration of industries and also have a dynamic impact on urban economy,which is the main realization of urban economic development;the exchange of materials,energy and information in cities reflects the efficiency and efficiency of trade and cooperation,and is the ultimate embodiment of industrial linkages and enterprise development.The correlation strength and structure of the relationship between the main elements of the urban agglomeration characterizes the integration of resource elements and the degree of labor division.The radiation-driven ability and functional support of the key factors affect the efficiency and efficiency of urbanization.Therefore,in the process of promoting the development of urbanization and formulating the urbanization strategy,it is necessary to consider the influence of the industry,enterprises and cities in the urban agglomeration and their intra-layer and inter-layer related structures on the urban economy.In order to promote the process of urbanization based on the economic development of urban agglomeration.it is necessary to open a new perspective in the study of urbanization development and pay attention to the macro background,influencing factors.internal mechanism and structural evolution trend of urban development.In this paper,the main elements of the various levels of the urban agglomeration economic system are integrated under one framework for integration.Considering the impact of the industrial input-output relationship and the business relationship on urban development,and the strategic development of urbanization is studied with the super network idea.Super network exists in the reality system formed by the interweaving of many single networks,which can describe the complex system more comprehensively and gradually become a new method to study the real problem.Therefore,this paper introduces the super network analysis method,constructs the urbanization development super network model based on the urban agglomeration economic system,and describes the intra-layer and inter-layer interactions of the various levels of the main body in the process of urbanization development from the perspective of the association structure.It is of great significance for formulating scientific and effective urbanization development strategy and promoting high-quality economic development.Specifically,this paper mainly completes the following research contents:(1)This paper analyzes the connotation and mechanism of the influence of the main element association on the urbanization development in urban agglomeration,and constructs the super network model of urbanization development.As the main carrier of urbanization development industries,enterprises,cities and their related structures in urban agglomeration are the key factors affecting the development of urbanization.The essence of the association of urban agglomerations is the different levels and unique cooperation networks formed on the basis of industry and geographical division of labor.The core is the integration and coordination of resources across regions,and the foundation is the input-output relationship of regional industries.Therefore,in chapter 3,based on the analysis of the factors of urban agglomeration economic system and their relationship to the development of urbanization,the industry,enterprise and urban network are constructed respectively,and based on their inherent attributes and logical relationships,based on the super network theory coupling three Linking the main elements of the layer to construct a super network model for urbanization development.(2)Design the measurement index for intra-layer and inter-layer structure of urbanization development super network.The construction of the super network model of urbanization with clear economic meaning and operation requires not only clear application objectives and reasonable description tools,but also the construction of indicator design and indicator system.This paper analyzes the internal and inter-connected structures of industries,enterprises and cities from multiple dimensions,and measures the impact of single-level and multi-level elemental associations within urban agglomerations on urbanization.For example,based on sub-network local correlation structure indicators(Node Degree,Node Betweenness and Betweenness),key nodes and edges in the layer can be identified from the perspective of intra-layer association.Based on the overall correlation structure index of subnetwork(Core Structure,Basis Structure and Cycle Structure),the key supporting structure in the single-layer network can be identified.Based on the local association structure index of the super network(Node Super Degree and Node Super Centrality),key nodes of inter-layer interaction can be identified from the perspective of inter-layer association.Based on the overall correlation structure index of super network(Superedge Connectivity,Superedge Similarity and Superedge Distance),the most influential industry,enterprise and city combination in the system can be identified.The structural characteristics of these subject associations can provide a quantitative basis for formulating urbanization strategies and promoting the coordinated development of urban economy.(3)Apply the research on the strength and structure of the related factors in the urbanization development of Shandong Province.Shandong province is in an important period of economic transformation and upgrading and rapid development of urbanization,as well as a key period of strategic transformation from large to strong.The development of urbanization in Shandong province needs not only the cooperation of the main body of factors within the province,but also the support of the main body of factors outside the province.Therefore,by constructing the urbanization development super network of Shandong itself and the elements related to the beijing-tianjin-hebei urban agglomeration and the Yangtze river delta urban agglomeration,and analyzing the relationship and structure between the main factors,we find out the key industries,enterprises and cities and their combinations supporting the urbanization development of the province.Based on the results of the analysis,the paper puts forward some suggestions on the problems in the development of urbanization,and verifies the scientificity and effectiveness of the construction method and index calculation of the super network model for the development of urbanization.This paper has the following innovations:(1)analyze the urbanization development from the perspective of relevance.In this paper,we study the influence of intra-layer and inter-layer associations of different attribute entities such as industry,enterprise and city within the urban agglomeration on urbanization development.First of all,the position and role of the main body such as industry,enterprise and city in the process of urbanization are defined,and the relationship between the main body factors that influence the development of urbanization is expanded from single attribute and single level subject relationship to multi attribute and multilevel subjects.Furthermore,the definition of urbanization development based on element relationship is as follows:through orderly association movement of multi-attribute and multi level factors in the urban agglomeration economic system,it promotes the formation of ordered association structure in the subsystem level and between layers.And find out the key nodes and structures within the subsystem layer and between the layers,and play its core radiating role,so as to achieve multi-level,multi-faceted mutual benefit and economic structure optimization of the urban agglomeration economy,and finally promote the development of urbanization.(2)Integrate the idea of super network into the construction of urbanization development model.Super network provides an effective tool for studying the subject-related structure of multi-attribute,multi-objective and cross-level features in social and economic life.Based on the super network theory abstract urban agglomeration economic system,this paper integrates the main elements of different attributes such as industry,enterprise and city into a unified framework for analysis.This paper constructs a super network model which includes the key subjects of urban economic development and reflects the inter-level and inter-level relation of the main elements in the process of urbanization.Taking Shandong province's urbanization development super network as an example,the paper applies the research to further identify the key industries,core enterprises and important cities in Shandong's urbanization development,and provides a model basis for determining the broad,strong supporting industries,enterprises and urban combinations,and enriches the research contents and research methods of Urbanization to a certain extent.(3)Designed intra-layer and inter-layer structure metrics with clear and operational economic implications.The paper analyzes the characteristics of industries,enterprises and cities within the main body and the related characteristics among them,and finds the key elements and their related structures that affect the development of urbanization.The specific indicators include sub-network-based local association structure indicators(Node Degree,Node Betweenness and Betweenness),sub-network-based overall association structure indicators(Core Structure,Basis Structure and Cycle Structure),super network-based local association structure indicators(Node Super Degree and Node Super Centrality)and hypernetwork-based overall association structure indicators(Superedge Connectivity,Superedge Similarity and Superedge Distance).The paper also makes an example calculation of the super network structure of Shandong's urbanization development,and finds out the key factors and their related combinations that affect the development of Shandong's urbanization.These indicators enrich the design index system of urbanization development to a certain extent.
