Research On The Regional Spatial Effects And Mechanism Of High-speed Rail New Towns In The Periphery Cities Of Guangdong-Hong Kong-macao Greater Bay Area

With technological changes,high-speed rail has become an important means of transportation for regional connections.However,the rapid construction of China’s high-speed rail and the rapid urbanization period have been carried out at the same time,which has triggered a boom in the construction of new high-speed rail cities.High-speed rail accelerates the rate of resource flow between regional cities,but different urban development conditions lead to different spatial effects of high-speed rail new cities.High-speed rail construction has positive and negative effects on regional peripheral cities,triggering the dilemma of high-speed rail new city construction.Therefore,there is an urgent need to innovate the system and mechanism of multi-party cooperation in the construction of high-speed rail new cities.Through a research summary on the characteristics,influencing factors,and mechanism of the regional spatial effects of the new high-speed rail city,it points out the deficiencies of existing research.The negative effects,policy factors,and multi-subject interaction mechanism of the highspeed rail new city in the peripheral cities are important entry points.Secondly,it summarizes the relevant research on the theory of urban government,and points out that the theory of urban government is based on the external environment and internal mechanism to construct an analysis framework,and considers the relationship between the central and local governments in the external environment under China’s national conditions.On the basis of the above,this study takes the spatial effects of high-speed rail new cities in regional fringe cities as the research object.Based on the theory of urban political system,according to the characteristics of regional fringe cities and high-speed rail new cities,a new type of external development relationship(inter-government relationship,inter-city relationship)and The analysis framework of internal development relations(government,market,and the public)emphasizes the important role of the railway sector and regional core cities in the development and construction of high-speed rail new towns in regional fringe cities,and analyzes the game and cooperative relationship of multiple subjects in the construction of high-speed rail new cities in regional fringe cities.The mechanism behind the regional spatial effect of high-speed rail new cities in regional fringe cities.Through the empirical research on Shaoguan High-speed Rail New City,the main urban space effect and internal space effect of the high-speed rail new city of regional fringe cities are analyzed.In terms of the spatial effect of the main urban area of the high-speed rail new city,it promotes the growth of urban land in the main urban area,increases the economic density of the main urban area,promotes the agglomeration of manufacturing enterprises in the main urban area,and promotes the main urban area to form a new growth pole in the high-speed rail new city.But at the same time,it also reduces the employment density in the main urban area,restrains the growth of commercial land in the main urban area to a certain extent,and restrains the concentration of financial institutions in the main urban area to a certain extent.In terms of the internal space effect of the high-speed rail new city,promote the layout of the innovative industry platform of the high-speed rail new city at the high-speed rail site,and promote the agglomeration of the productive service industry of the high-speed rail new city at the high-speed rail site.However,there are also negative spatial effects.The high-speed rail new city focuses on residential functions and is separated from the main urban area;the high-speed rail new city lacks functional coordination with the main urban area,and there is homogeneous competition;the high-speed rail new city differs in the quality of industrial space and residential space;The supporting facilities of the high-speed rail new city are not perfect,and the city atmosphere is insufficient.Based on the theory of urban polity,it analyzes the mechanism of the spatial effect of high-speed rail new towns in regional fringe cities from the external development relationship and the internal development relationship.The external development relationship includes the central-district relationship between the city government and the Ministry of Railways and the inter-city relationship between the city government and regional core cities,which respectively affect the site selection and construction of high-speed rail stations and the industrial development of high-speed rail new cities.The city government is actively planning to facilitate the site selection of high-speed rail stations in line with the interests of urban planning,and lays the foundation for the growth of urban land in the direction of high-speed rail new towns.Due to the location advantages of the highspeed rail and the comparative advantages between cities,the industrial alliance between the city government and the regional core cities can build a benefit distribution mechanism.The marginal cities provide land,and the core cities provide capital,enterprise resources and information resources to promote the core cities along the high-speed rail lines.The transfer of industries and the advanced theories of industrial development in core cities have promoted the development of information service industries in the new high-speed rail city.The internal development relationship includes the alliance of the public sector,the alliance of the public and private sectors,and the alliance of the public sector across internal and external sectors.In the alliance of the public sector,the alliance within the city government lays the foundation for the governance of the new high-speed rail city and enhances the administrative status of the new high-speed rail city;the alliance between the city government and the urban investment company accelerates the development of the new high-speed rail city;the alliance of the functional zone management committee,To promote the complementation of advantageous resources and the platform for innovation and entrepreneurship to be deployed around high-speed rail stations.In the alliance between the public and private sectors,the development alliance between the city government and the villagers ensures the social atmosphere of the new high-speed rail city;the development alliance between urban investment companies,the real estate industry,and the citizens leads to low real estate quality;the development alliance between the city government and financial institutions,As a result,the policies of financial clusters are strong,and the effectiveness of market resource allocation is reduced.The alliance across the public sector inside and outside provides capital and technical support for the industrial platform of the high-speed rail new city,and promotes the agglomeration of high-tech industries.Due to the limited urban economic level of regional fringe cities,they are dominated by regional core cities in the regional economy.There are three main problems in the construction of the new high-speed rail city: the construction of the new high-speed rail city is mainly promoted by the government,and market forces are weak;urban development and construction are overly dependent on urban investment companies and land finance;citizen participation is low,and planning information is not obtained equally.Three countermeasures are proposed in response to the above problems.High-speed rail sites are combined with industrial parks to develop high-tech manufacturing and information service industries;to clarify the power and responsibility boundaries between the government and urban investment companies to promote marketization of urban development and construction;and to strengthen information disclosure and public supervision.This research takes the Guangdong-Hong Kong-Macao Greater Bay Area fringe city high-speed rail new city as the research object,based on the theory of urban government,innovates the research framework of the external development relationship and internal development relationship,and analyzes the main urban space effect,internal space effect and space of the regional fringe city highspeed rail new city The internal mechanism of the effect provides new development ideas for the construction of high-speed rail new towns in regional fringe cities.The main text is divided into seven chapters.The first chapter is the introduction,which introduces the research background,research purpose and research significance,explains related concepts,and introduces the research content and framework.The second chapter is the research summary,which summarizes the related research on the theory of high-speed rail new city and urban political system.The third chapter is the research framework and research design.Based on the theory of urban political system,it constructs the basic framework for the research on the regional spatial effects of high-speed rail new cities,and introduces the research objects,research methods and data sources.The fourth to sixth chapters are the empirical analysis part,taking Shaoguan,Guangdong as a case,to explore the mechanism of the main urban space effect,internal space effect,and space effect of the high-speed rail new city.Chapter 7 is the conclusion and discussion.Summarize the main conclusions,research deficiencies,and future research directions of the article.The whole thesis contains about 49 000 words,59 pictures and charts.
