Abstract:

The development of smart cities in China has undergone phases of localized exploration and sectoral integration, and is now fully entering the stage of integrated development. The new era’s critical goal for comprehensive urban digital transformation involves coordinating the integration of technology, business, and data to enhance collaborative management and service levels across multiple layers, regions, systems, departments, and business domains. In recent years, various regions have actively promoted the construction of city-wide foundational platforms, resulting in the preliminary formation of several integrated capability platforms. However, issues such as redundant construction, repeated overhauls, underutilization, and challenges in supporting complex cross-sectoral scenarios have gradually emerged. This paper proposes a systematic approach to building a foundational platform for urban digital twins from perspectives including data integration and utilization, efficient reuse of capabilities, rapid scenario construction, and sustainable iterative development. It introduces innovative concepts for constructing a digital twin entity, a capability component system, an open service system, and a sustainable operation system.
