Spatio-temporal Full-cycle Integrated Framework for Old Residential Community Renovation: Theoretical Construction, Mechanism Analysis, and Case Study

The renovation of old residential quarters often faces challenges such as lack of spatio-temporal coordination and fragmented governance. Integrating theories of whole-cycle management, spatial production, and sustainable development, this study develops a spatio-temporal whole-cycle integrated framework comprising temporal, spatial, and governance dimensions, and delves into its underlying mechanisms and empirical validity. The analysis reveals that the spatio-temporal interaction mechanism maintains a dynamic balance between tasks at different stages and the allocation of spatial resources; the governance empowerment mechanism is underpinned by multi-stakeholder collaboration, institutional support, and digital enablement, while the feedback and optimization mechanism ensures closed-loop control and continuous improvement throughout the renovation process. Finally, a preliminary validation was conducted using the Jinniu Flower Garden project in Shanghai, with the aim of providing theoretical foundations and implementation pathways for the renewal of old residential quarters, thereby promoting a more sustainable governance model for urban regeneration.
