ABSTRACT: Under the background of accelerating new urbanization process, smart urban renewal has been transformed from “incremental construction” to “stock optimization”, and the traditional renewal mode is difficult to meet the demand of sustainable urban development due to data silos and lack of dynamic simulation. Based on digital twin technology, this paper explores the application path of smart urban renewal by constructing its technical framework, aiming to provide a full life cycle digital solution for urban renewal. The study proposes a layered architecture technology framework, covering perception layer, data layer, platform layer, application layer and user layer, integrating key technologies such as Internet of Things, three-dimensional modeling, big data analysis, etc.; designing a four-phase application path including status quo assessment, program design, implementation monitoring and operation and maintenance optimization, and carrying out an empirical analysis by combining the case studies of Qianhai, Shenzhen and Xiong’an New Area. The study shows that digital twin technology can significantly improve the planning science, construction efficiency and operation and maintenance intelligence of urban renewal, providing theoretical and technical support for smart urban renewal practice.
