Exploration of an Urban Renewal Evaluation Method Based on Stock Spatial Assets:A Case Study Based on the Central Urban Area of Jiangmen City
As the value orientation of urban renewal objectives shifts,there is a growing emphasis on the sustainability of urban renewal,which is determined by the balance between the inputs and outputs of redevelopment projects.Such balance encompasses both the short-term static equilibrium during the redevelopment phase and the potential for long-term fiscal dynamic equilibrium.Most existing urban renewal assessment methods predominantly focus on short-term economic feasibility,which may somewhat deviate from the value orientation of contemporary urban renewal goals.By introducing the"asset-based"theory,an evaluation method for urban renewal based on stock spatial assets was proposed to achieve long-term comprehensive benefits in urban renewal.In the early value evaluation of urban renewal,the possibility of the long-term effective operation of assets was analyzed from the macroscopic perspective.First,stock spatial assets in central urban areas were identified based on physical assets,social assets,human assets,and the three categories of property rights holders(including government,enterprises,and individuals)from five aspects of low-efficiency land use,idle buildings,available resources,fundamental value,and willingness to renew.Second,the scope of redevelopment patches within the land and the method of renewal and renovation were determined.Five aspects of the stock spatial asset pool were evaluated according to value orientations of industrial space,residential space,and service space using the Analytic Hierarchy Process(AHP)and the Delphi method.Finally,the expectations of identifying different redevelopment entities,including government,owners,and enterprises,to the reutilization of stock resources were noted.The implementation methods and strategies for realizing stock spatial asset value were determined with comprehensive considerations of value recognition and evaluation results of stock spatial assets under different space types and reconstruction modes.The study finds that areas with high stock spatial asset value in residential spaces in the central urban area of Jiangmen exhibit a polycentric pattern.The reconstruction focuses on utilizing physical and human assets,with the government and individuals as the primary property rights holders.It can bring sustainable operational incomes from taxes and rents by introducing social capital,resident fee usage,and government coordination to maintain a balanced urban renewal budget.Key attention is paid to environmental upgrading and multi-party management strategies.The stock spatial assets of industrial spaces are in the geometric center of the central urban area in Jiangmen City,with a gradual decrease in peripheral regions.The involved types of stock spatial assets are mainly comprised of physical and social assets,and government and enterprises are the primary property rights holders.The reconstruction involves large-scale social capital introduction,regional upgrading,and functional transformation strategies through government coordination,enterprise leadership,and large-scale renovation.The stock spatial assets of service spaces are primarily located in the centers of Baisha Street and Huicheng Street,mainly covering physical and social assets,where government and enterprises are the primary property rights holders.It aims to convert idle service spaces into active places with economic value.The strategies of service updating and effective long-term operations can be implemented through government leadership,enterprise operation,and organic renewal.In the current context of urbanization,cities have entered into a phase of stock development.Jiangmen City represents many developing cities.They are shifting from a traditional demand-based urban renewal planning model to an asset-based sustainable development model.This can stimulate the intrinsic motivation for renewal and promote the development and self-construction of stock spaces by viewing stock conditions as assets.The urban renewal evaluation method is optimized based on the reuse of stock spatial assets.The urban renewal planning framework based on assets will provide a theoretical foundation and some analytical methods for urban renewal.
