According to a recent article on the website of Brazil's "Please See" magazine titled "Continuous Mountains, Skyscrapers, and Tunnels: How Chongqing, China Became the World's Largest Urban Laboratory", focusing on the achievements of smart city construction. The article states that, like many other Chinese cities, technology is seen as the core driving force for Chongqing's urban development. This smart city relies on a large-scale data monitoring and analysis system to continuously optimize the daily operational efficiency of the city. When the global urban space is generally facing the dilemma of saturation, China is proving through practice that with data empowerment, engineering innovation, and planning ambition, new dimensions of cities can always be opened up. According to Russian media Dzen.ru, Shenzhen, China won the "World Smart City Award" for 2024 at the Global Smart City Conference. According to reports, Shenzhen has solved problems such as high population density, limited resources, and the environment through digital construction, advanced urban management methods, and sustainable development concepts, thereby achieving urban transformation. It will also create a new model of smart city through high-speed broadband access, digital twin technology, artificial intelligence, and other means. In recent years, China's smart city development has achieved remarkable results, and a number of scalable smart city construction achievements have been formed in various regions. Firstly, the foundation of urban data is becoming increasingly solid, and various regions are deploying data infrastructure in advance, exploring the integrated model of "collection, storage, calculation, management, and security", breaking through data sharing bottlenecks, building urban intelligent centers, and promoting data service coverage across the entire region. Secondly, the application scenarios of data are becoming increasingly diverse, with the emergence of characteristic applications such as "no proof of service", intelligent diagnosis of health and wellness, and carbon inclusive services for residents, which improve the quality and efficiency of urban economy, governance, and services. The third is continuous innovation in the digital transformation ecosystem, exploring new models such as data zones, cross-border flows, and data specialists in various regions, and promoting innovative practices in basic systems such as data property rights, transactions, revenue distribution, and security governance. The development of smart cities in China presents distinct characteristics. In terms of promoting ideas, we focus on "systematic planning and overall reshaping". Innovate the digital transformation planning system in various regions, reshape the technological architecture, and promote integrated construction and business collaboration. In terms of building mechanisms, we practice the concept of "data fusion and model intelligence". The development model of "AI CITY" is gradually emerging, transforming information systems through "big models+knowledge bases", using the ability of big models to train city big models, creating urban intelligent agents with self perception, adaptive and other capabilities, and improving the intelligence level of cities. In terms of mechanism mode, emphasis is placed on "integrated operation and long-term operation". Innovate work models and long-term mechanisms in various regions, stimulate the vitality of market entities, and promote the transformation of urban digital transformation from "rebuilding light transportation" to "coordinated management and operation". The in-depth development of smart cities in China cannot be separated from policy guidance and technological innovation. On the one hand, a series of policy measures provide direction and guarantees for the construction of smart cities. The report of the 20th National Congress of the Communist Party of China proposed to strengthen urban infrastructure construction and create livable, resilient, and smart cities. As early as 2014, the National Development and Reform Commission and eight other ministries jointly issued the "Guiding Opinions on Promoting the Healthy Development of Smart Cities"; In 2016, China proposed the construction of a new type of smart city with Chinese characteristics, emphasizing data-driven, people-oriented, coordinated and intensive, and practical results; In May 2024, the National Data Administration, together with the National Development and Reform Commission, the Ministry of Finance, and the Ministry of Natural Resources, issued the "Guiding Opinions on Deepening the Development of Smart Cities and Promoting the Digital Transformation of Cities", proposing to use cities as comprehensive carriers for promoting the construction of Digital China, and to integrate and develop data throughout the entire process of urban digital transformation and construction. On the other hand, a series of intelligent technologies are accelerating their application, providing strong impetus for the construction of smart cities. For example, Internet technology supports the interconnection of all things and promotes the interconnection of all aspects and elements in urban governance; Big data technology supports the construction of a "hologram" of urban operation, helping to gain a more comprehensive and accurate understanding of the city's operational status, and achieving forward control and source management; Artificial intelligence runs through all aspects of urban planning, design, construction, and management, driving the advancement of urban intelligence and effectively enhancing the city's ability for precise governance and public service efficiency; Blockchain technology changes the way data and information are connected through new trust mechanisms, providing effective technical means for trusted data interaction. With the acceleration of global urbanization, smart cities, as a new type of urban development model, are receiving high attention worldwide. China's development experience in this area can provide reference for other countries and regions in the world: emphasizing both institutional and technological aspects, emphasizing the overall reshaping of technological architecture, and promoting digital institutional innovation. Emphasize both construction and operation, innovate the operation and maintenance mode, and establish a long-term operation mechanism throughout the entire lifecycle. Emphasize both the central and peripheral aspects, establish a common foundation for urban digitization, improve the intelligent central system, and pay attention to the intelligent perception and response of peripheral areas. Give equal importance to both data and scenarios, and promote data circulation, utilization, and scenario innovation around data infrastructure systems and scenario applications. Give equal importance to development and security, coordinate high-quality urban development and high-level security resilience construction, and expand the scope of smart city security. In the future, with the continuous deepening of smart city construction, China will continuously iterate and upgrade its development model, share development experience with the world in a more open and inclusive manner, and work together to build a more intelligent, green, and humanistic future urban community, making smart cities a beacon that illuminates the future of human urban civilization.
