General Secretary Xi Jinping pointed out in the article "Several Major Issues in the National Medium and Long-term Economic and Social Development Strategy"，“Enhance the economic and population carrying capacity of central cities and urban agglomerations and other areas with advantages in economic development，This is in line with objective laws”，with special emphasis，“To promote urban group development，Formation of polycenters、Multiple levels、Multi-node bet365 games structure”。These important remarks made by General Secretary Xi Jinping are consistent with the development trend of multi-centered networked urban agglomerations in the world today，Points out the direction for my country’s future urbanization road。

　　The bet365 games trend and problems of multi-centralization

The rapid development of rapid transportation and information technology and the rise of "flow space"，Greatly changed the regional economic spatial pattern of today’s world，The spatial structure represented by "bet365 games" has become an important feature and common phenomenon in highly urbanized areas around the world。

The core feature of the bet365 games structure is the multi-centered spatial development trend。The so-called polycentric spatial structure includes two dimensions: "morphological polycentricity" and "functional polycentricity"。“Polycentric form” mainly refers to cities of roughly equal size、The spatial distribution is relatively uniform，Static data analysis methods mostly based on population (employment) size and density，Reflects the absolute importance of a node。And "multi-functional center" emphasizes the external connections of nodes，And this relationship is multi-directional，Pay more attention to the importance of each spatial node’s position in the entire regional network。It is characterized by simultaneously considering the traffic volume and directionality between all cities in the urban area，What it wants to build is a horizontal (horizontal) network relationship。Therefore，The spatial structure formed based on such a horizontal network relationship is not a unidirectional spatial layout formed around a central place in the traditional sense (such as a garden city)，And tend to build a multi-level structure、Multi-node spatial layout with multi-directionality。For an ideal bet365 games structure，"Polycentricity of form" and "polycentricity of functions" complement each other、Indispensable。

At present, related research has become a hot spot in Western urban and regional spatial research。From the "European Spatial Development Strategy" which first proposed the policy goal of polycentric development to the "European Polycentric Mega City Regional Sustainable Development Management Project"，The EU continues to promote the planning and construction of multi-center urban areas，Promote polycentric urban area research from the academic field to the applied field。The "European Spatial Planning Observation Network" funded by the EU is committed to providing empirical evidence for the polycentric development of European networked urban agglomerations，To promote the continuous expansion of its research scope、Research content continues to be enriched and deepened。It can be seen from this，The multi-centered bet365 games structure has become a way to enhance regional development competitiveness，An important spatial organization tool to promote coordinated regional development。Constructing a polycentric bet365 games structure can help solve the problems faced by regional space across administrative boundaries in the development process，It has great practical significance for enhancing my country’s international competitiveness。

In the process of rapid urbanization in my country，Multi-centered network urban agglomerations are taking shape，has become an important spatial organization tool to enhance regional development competitiveness and promote coordinated regional development。However，There are still some problems that need to be solved in the development process of my country's bet365 games structure。

First，Looking at the various bet365 games agglomerations (circles) that have been identified so far、With)，There is a certain "form" and "virtual" in it，The "reality" of "function" needs to be improved。Plane splicing between cities and bet365 games units，Need to further break the constraints of the original administrative boundaries，In this way, various resource elements (such as people) can be realized、Object、Message、Funds of capital and technology, etc.) flow freely between adjacent nodes and space areas。Second，The phenomenon of “polarization” in development policies is still emerging to varying degrees，This has hindered the coordinated development between cities at different levels to a certain extent。From the perspective of the current polycentric spatial structure development model of bet365 games agglomerations in my country，The "one pole" among the "two poles" has the characteristics of "one city dominates"，The other "pole" is a city of similar size、Energy level convergence，There is no significant level difference between them，The bet365 games pattern presents a typical "flat" development。Third，In infrastructure construction, "response to requests" and "preparation for rainy days" should be further strengthened。The infrastructure used to strengthen interconnection between cities needs to meet market demand while，Reasonable spatial arrangement of existing infrastructure in cities and regions，There is still room for further deepening of supply-side structural reform in this field。Fourth，The governance model needs to be “integrated vertically and horizontally”。With the formation of networked bet365 games agglomerations across administrative boundaries，The "internal problems" faced by traditional single cities eventually evolved from the inside out into the "external problems" between cities，These problems have exceeded the administrative jurisdiction and capabilities of a single city government。

　　Optimizing the development path of bet365 games structure

In the modern regional economic pattern，Central cities and urban agglomerations have strong agglomeration capabilities、High space efficiency，Obvious scale effect，Is the most active growth pole and power source for economic development。For this，The development path of networked bet365 games should be optimized through the following aspects。

First，Build a polycentric network-type bet365 games across administrative boundaries based on mutual functional connections。With the expansion of “flow space”，Metropolitan area、The construction of multi-center spatial structures such as urban agglomerations must not only have the "virtual" of "form"，We should follow the "reality" of "function"。Therefore，A spatial planning method that determines “shape” by “flow” should be adopted，Breaking the inherent administrative boundaries，Based on whether there is rapid flow of various resource elements between cities，Then it tends to form a networked bet365 games as an important criterion for scope definition。It should also be pointed out that，The boundaries of the spatial structure of urban agglomerations are not statically fixed，It should be dynamically changing。To some extent, it is a reflection of the socio-economic characteristics of cities and regions at a certain stage。Therefore，It should be adjusted accordingly with the development of cities and regions，To meet the needs of social and economic development in the region，This will then help government departments formulate the most effective urban planning and management policies。

Second，Promote and achieve coordinated development among cities of different levels，Construct scale mutual loan、Complementary functions、New urban agglomeration spatial structure of industrial mutual assistance。The original intention of building a multi-center bet365 games spatial structure is to reduce negative externalities，Optimize the space allocation of resources，Form the aggregation effect of "one plus one is greater than two"，Promote regional economic integration development。In this development process，Should be based on overall planning、Reasonable layout、Perfect functions、The principle of leading the small with the big，Follow the objective laws of urban and regional development，Relying on big cities、Focus on small and medium-sized cities，Gradually forming "multi-center"、Multiple levels、Multi-node bet365 games structure”，Promote the coordinated development of large, medium and small cities。Discovered in empirical research，Only when the population sizes of cities within the same urban agglomeration are equally distributed，It is most conducive to improving the overall labor production efficiency of the region。Therefore，The development of urban agglomerations should not over-concentrate population and economic activities in a single central city，The gap in population distribution and economic development between large, medium and small cities should be controlled within a reasonable range，To form two-way communication、Interoperability and complementation、Healthy and orderly urban agglomeration spatial structure。

　Third，Actively improve the network layout of infrastructure，Improve the level of interconnection between cities，Promote the effective expansion of “flow space” and regional integrated development。The interconnection of infrastructure is a prerequisite for building a polycentric spatial structure，It is also a strong support for promoting the economic and social integration development of bet365 games agglomerations。Therefore，Cross-level should be actively and comprehensively promoted、Integrated collaborative planning and design of public infrastructure across administrative boundaries (such as large-capacity rapid public transportation represented by rail transit)、Collaborative construction and collaborative operation，Promote the network layout of infrastructure。In addition to physical space planning methods oriented to shorten physical space distance，We should also pay attention to the improvement of the application of information network technology in order to reduce the diffusion resistance of "human capital flow" and "technical information flow"。Therefore，We should start from the perspective of integrated development of bet365 games agglomerations，Accelerate 5G network、Big Data Center、Artificial Intelligence、Moderate advance planning and layout of “new infrastructure” such as the Internet of Things。

　Fourth，Further improve the networked governance model of bet365 games agglomerations，Maximizing synergy effects。According to the new situation of my country’s urbanization development，The networked governance of bet365 games agglomerations places greater emphasis on the integrity and synergy between city governments in the region。Therefore，Must innovate and develop communication and cooperation mechanisms among multiple governance entities，Establishing benefit sharing、Mutual cooperation、Modern bet365 games agglomeration network governance model of collaborative governance。First, efforts should be made to break down bet365 games localism and administrative barriers，Construct a goal task oriented to maximizing the overall benefits of the bet365 games agglomeration；Second, the market and social organizations should be actively developed to improve the networked governance framework of bet365 games agglomerations；The third is to actively build e-government as a carrier、Information resource sharing and public service mechanism supported by big data (such as inter-governmental office information platform、Regional Information Comprehensive Service System、Co-construction and sharing of geographical information application systems for bet365 games agglomerations, etc.)。
