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.
In the context of constructing a Digital China, data governance has entered a new stage of development. As a fundamental project in the construction of Digital China, data governance is not only related to the modernization of the government’s governance capacity, but also an important guarantee of national data security. However, data governance currently faces challenges such as inconsistent framework, unclear authority and responsibility, and insufficient technological innovation. To further improve the level of data governance, based on the level and content of digital governance, this paper proposes that digital governance should adhere to the construction principles of strategic thinking, rule of law thinking, innovative thinking and systematic thinking, and build a data governance system with Chinese characteristics by unifying the governance framework, clarifying the boundaries of authority and responsibility, strengthening technological innovation, and optimizing the governance ecology.
City scenario innovation, as an important measure for the new industry-city integration development, has received widespread attention from both industry and academia.
