Marked by the approval of the Shanghai Master Plan(2017-2035)by the State Council in 2017,Shanghai has ushered in an era of urban renewal characterized by the redevelopment of existing land.Based on a brief exposition of Shanghai's innovative approach to urban renewal,which is characterized by government organization,planning guidance,functional enterprise leadership,and multi-stakeholder participation in the operation of urban renewal and style preservation,this paper delves into the practical implementation aspects of preserving Shanghai's urban style.It identifies several bottlenecks,including the high cost of land development,challenges related to capital and development logic,difficulties with policies concerning stock transformation,conflicts between property rights and development usage,and legal constraints in preserving historic buildings.To address these issues,the paper proposes targeted solutions such as reducing the benchmark land price for construction land in urban and rural areas,optimizing capital allocation and development logic in urban renewal,exploring a"lease-to-own"land supply model,separating the management of ownership and usage rights for historic buildings,and revising relevant legal provisions.These measures aim to facilitate better preservation of Shanghai's unique urban style.
