Research on Renewal Planning of Modern Service Concentration Area Under theBackground of Built up Area Planning: A Case Study of Yuzhong District, Chongqing

Modern service industry cluster is an important carrier of urban service industrytransformation and development. Under the background of stock planning, the expansion ofservice agglomeration is restricted, especially in big cities with high built-up area density, andurban construction land has tended to be saturated. Therefore, renewing the original industrialagglomeration space in the city has become a development trend of modern service agglomerationarea. In the field of urban renewal, the renewal of service agglomeration is a relatively newresearch subject, and a complete renewal research system has not been formed yet. Based onthis background, this paper briefly discusses the main problems faced by the renewal of modernservice industry cluster and the corresponding renewal approaches, and takes the renewal planningof modern service industry cluster in Yuzhong District of Chongqing as an example, in order toprovide reference for the subsequent research.At present, the research on modern service industry agglomeration area is mostlyconcentrated in the eastern developed cities such as Shanghai and Guangzhou, and theresearch on the less developed areas is relatively few. According to the existing studies, thereare problems such as weak agglomeration effect and insufficient spatial quality constructionin service agglomeration areas. Based on the problem orientation, this paper establishes therenewal framework system of modern service agglomeration under the background of stockplanning, proposes that the renewal planning of agglomeration should firstly evaluate theindustrial characteristics, spatial characteristics, development scale, development potential andother aspects of the development of agglomeration, comprehensively understand the developmentstage of agglomeration, and according to the process of industrial development from success todecline. The development stages of agglomeration areas are divided into growth stage, maturitystage and stagnation stage, and the regeneration types of agglomeration areas are summarized asgrowth type, maturity type and stagnation type. In view of the problems existing in the renewalof modern service industry agglomeration, the paper discusses the possible renewal strategiesof different types of agglomeration from three aspects: industrial development orientation,industrial spatial layout and agglomeration environment construction.Taking Yuzhong District of Chongqing as an example, this paper summarizes the developmentprocess and problems of Yuzhong industrial cluster, and constructs an evaluation index system ofcluster development scale, development potential, facility conditions and industrial developmentfrom the current situation of Yuzhong industrial development and the current spatial characteristicsof the cluster, with a total of 10 evaluation indexes. Based on the identification of agglomerationtypes, the service industry agglomeration in Yuzhong District is divided into three types accordingto the score, including stagnation type, mature type and growth type. The analysis results showthat there are many modern service industry agglomeration areas in the stable development stagein Yuzhong District, and a considerable number of agglomeration areas are facing stagnation. Inthis paper, Daxigou Cultural and creative Agglomeration area in Yuzhong District was taken as anexample to discuss the renewal strategy of stagnant service agglomeration area, including defining the industrial direction of cultural creativity, Internetinformation and professional services as the leading industries, delineating three industrial spaces, adding characteristic public spaces, optimizing trafficorganization, etc.Under the background of spatial planning and construction, how to grasp the spatial relationship and realize the development of industrialagglomeration in modern service industry agglomeration area is a problem worthy of attention. This paper discusses the development path of the modernservice industry cluster under the background of stock planning. The main contributions are as follows. Firstly, it provides reference for the developmentpath of the same type of service industry cluster. Taking the renewal planning of the modern service industry cluster in Yuzhong District of Chongqing as anexample. Secondly, from the overall perspective, it evaluates the development status and characteristics of the service industry cluster based on the problemorientation, and puts forward the renewal strategies targeted by different types from the aspects of industrial development, spatial layout and environmentalquality, so as to realize the industrial development, spatial quality improvement and attractiveness enhancement of the cluster. The research results aim toprovide constructive suggestions for the planning of other modern service industry clusters of the same type.
