城市存量土地更新的动力机制研究OA北大核心CSTPCD

As urbanization accelerates,cities encounter challenges related to limited spatial resources and mounting environmental pressures.The Outline of the 14th Five-Year Plan(2021-2025)for National Economic and Social Development and Vision 2035 of the People's Republic of China emphasizes the acceleration of urban development model transformation,coordination of urban planning and construction management,implementation of urban regeneration actions,and promotion of urban spatial structure optimization and quality enhancement.It considers the implementation of urban regeneration actions to be an inevitable requirement for adapting to the new situation of urban development and promoting high-quality urban development,as well as a key path for assisting high-quality urban development.In this context,urban inventory land regeneration has become an important means to optimize the pattern of urban development and improve the efficiency of resource utilization.Therefore,the study of the composition of inventory land,its characteristics,the causes of renewal and transformation,and the spatial production mechanism can help to provide some basic support for the design of differentiated regeneration systems,regeneration planning models and governance optimization paths. The paper first explains the meaning of"urban inventory land",which refers to land used for urban and rural construction that has low efficiency in land utilization and does not meet the needs of urban and social development.This type of land has the potential or demand for renewal,and has value for redevelopment and utilization.Considering the nature of land classification,land transfer methods,and spatial functional attributes,the inventory of land space will be aggregated into five basic types:1)residential category,which contains residential land;2)industrial category,which contains commercial service land,industrial and mining land,and warehousing land;3)public space category,which contains green space and open space land;4)public facilities category,which contains public service and public service land,transportation land,and public utility land;and 5)historical and cultural category,which contains cultural relics and monuments land,among others.Based on this,the text summarizes the spatial characteristics of different types of urban inventory land and the challenges they must address during the regeneration process. Secondly,a dynamic analysis framework for regeneration,influenced by the interaction of the three major driving forces of"power-capital-livelihood"was constructed.This framework,based on the three primary forces of urban regeneration-"government-market-society"-operates under the combined effects of power mechanisms,market mechanisms,and social mechanisms.It leverages the external impetus of power,the direct influence of capital,and the intrinsic demand of livelihood to facilitate various institutional designs and arrangements concerning collaborative efforts among stakeholders,funding allocation,and policy provision.These three mechanisms jointly promote the transformation of urban regeneration governance models,supporting differentiated institutional design and the effective implementation of regeneration projects. Thirdly,the paper provides an in-depth analysis and discussion on five distinct regeneration driving mechanisms for various categories of inventory land.These include the"government+society"collaborative renewal mechanism for residential inventory land,the"government+market"collaborative renewal mechanism for industrial inventory land,the government-led renewal mechanism for public facilities inventory land,the government-led renewal mechanism for public space inventory land,and the multi-party collaborative renewal mechanism for historical and cultural inventory land.Each mechanism is elaborated in terms of the typical regeneration models employed,sources of funding,collaborative methods,and challenges to be addressed,along with key considerations in institutional design.The aim is to offer a substantiated basis for the design of urban inventory land renewal systems and the optimization of governance pathways,thereby facilitating coordinated,healthy,and sustainable urban regeneration. Finally,based on the aforementioned research,and considering the current context of urban regeneration as well as the characteristics of the motivations and mechanisms behind the renewal and transformation of inventory land,this paper posits that future research on urban regeneration in China should focus on three key aspects:1)top-level decision-making.There is a need to strengthen research on strategies that attract social capital participation and leverage market forces for regeneration;2)path optimization.It is essential to establish a multi-objective,multi-stakeholder,and multi-type database of inventory land renewal planning cases.This database should distill,summarize,and delineate renewal paths for different types of land use,and explore urban inventory land renewal planning models and governance optimization pathways under multi-party participation in China;3)institutional building.The government urgently needs to establish and provide renewal systems.Based on the inherent logic of the characteristics of inventory land and the motivations for its regeneration and transformation,the collaborative mechanisms for urban regeneration involving multiple parties such as the government,market and society are discussed.
