市场主导城市更新的空间差异及政府因素影响OA北大核心CHSSCDCSTPCD

With the continuous progress in urban renewal in China,the spatial development of urban renewal brings increasing profound influences on cities.At present,market forces are gradually becoming a significant driving force to further promote urban renewal and development,while government intervention continues to play a crucial role in various manners.For the high-efficiency continuous promotion of high-quality development of urban spaces,it is necessary to get a comprehensive understanding on spatial differences of market-dominated urban renewal and influences of government factors on these.A case study based on the urban village redevelopment in Shenzhen was carried out.Spatial variation of market-dominated urban village reconstruction was explored by spatial analysis and multiple linear regression.Moreover,a quantitative analysis on the influences of government factors was conducted from the perspectives of urban planning,development construction density,and the decentralization of power to districts.Results showed that:(1)urban village reconstruction in Shenzhen primarily distributes along the southwest-northeast areas,concentrating in the central and some suburban areas,and less at the city margins.(2)Urban village reconstruction concentrates on core development urban areas with good traffic accessibility in the future,better economic development,and high development construction density through urban center planning,traffic routes,density-based zoning,and decentralization of power to districts by the reasonable guiding of market-dominated urban renewal activities.(3)On the one hand,the decentralization of power to districts has promoted the overall market-dominated urban village reconstruction in Shenzhen.Shortening time for administrative approval,early confirmation of executors and synchronous declaration of project and special plans are conducive to improve efficiency of market-oriented urban village reconstruction.On the other hand,it further brings significant spatial variation of urban village reconstruction among different administrative districts.Combined with recent national and urban policies on high-quality development of urban village reconstruction,it can be concluded that market-dominated urban village reconstruction in Shenzhen still requires appropriate government intervention to balance the realization of public interests and the protection of vulnerable groups.On this basis,several suggestions were proposed to further leverage market forces to promote high-quality development of urban village reconstruction in Shenzhen.Strengthening the formulation and implementation of policies in favor of urban center planning in some core development regions is suggested under the guidance of urban development layouts and urban center planning,such as increasing subway lines,main roads,as well as construction and planning of surrounding infrastructure.Additionally,increasing government funding in these areas is recommended,as well as appropriately adjusting their development intensity to enhance the expected returns of reconstruction projects and attract market entities.Finally,the municipal government must further coordinate and plan in administrative districts where it is difficult to promote reconstruction from the city's perspective,aiming to increase land resource utilization efficiency through reconstruction projects and achieving balanced sustainable urban development.The spatial variation of urban renewal was analyzed using the resulting quantitative data and influences of government factors were measured.Results provide important references for the implementation effects of market-dominated urban renewal activities and government interventions.In future studies,analysis width and depth should be increased.With considerations of different stages and modes of urban renewal processes,a deeper understanding on urban renewal development logics,and the promotion of high-quality urban renewal and urban development conforming to modern urban characteristics is needed.
