    • The development of urban e-government has gradually become an extremely important part of global e-government surveys. According to United Nations E-Government Survey 2022, the e-government levels in cities around the world have steadily improved in recent years, but the service provision of local governments is still inadequate, and regional disparities remain evident. This paper focuses on the perspective of urban e-government and analyzes the characteristics of local e-government development. It proposes that to improve urban e-government in the future, it is necessary to improve related strategies, enhance the level of data openness and sharing, and invest in digital innovative technologies.Besides, it is necessary to attract professional talents, prioritize the interests of vulnerable groups and provide humanized services.

    • Maturity is used to describe the development process of the assessment object from the low level to the high level. With the exploration of digital twin cities, how to effectively assess the development level and guide orderly construction has become an important proposition in the field of digital twin cities. Based on international and domestic maturity research, first, the connotation of digital twin city maturity is defined. Then, a maturity model of digital twin city is built, which classifies the characteristics of digital twin city from level 1 to level 5, and covers five dimensions and 19 indicators of digital twin city assessment. A quantitative assessment method is also proposed. Finally, suggestions are given for the application of the maturity model of digital twin city, which is expected to provide useful references for the assessment, certification and upgrading of digital twin city project.

    • Abstract ( 241 ) HTML( 132 )   
    • The digital twin plays an important role in intelligent manufacturing, ecological conservation, public services, urban governance and other fields, and is important content of the construction of a new smart city. Countries such as Japan, France, Singapore and America have taken the lead in the construction of digital twin cities. From the practical experience at home and abroad, to promote the construction of digital twin cities, it is necessary to pay attention to top-level design, reinforcing the base, application breakthrough, multi-participation and basic support, and strive to optimize the policy environment. Besides, it is necessary to expand application scenarios with distinctive features, build a unified data base platform, and promote government-led construction with social participation, so as to accelerate the construction of new infrastructure.

    • Information and Communications Technology and Policy. 2023, 49(8): 31-37. DOI:10.12267/j.issn.2096-5931.2023.08.005
    • Abstract ( 305 ) HTML( 189 )   
    • According to statistics, many cities across China have piloted the construction of new smart cities. In the planning, construction, and operation process of these new smart cities, there are a large number of data security risks and issues. How to comply with various data security laws and regulations issued by the country and do a good job in data security protection of new smart cities is a key aspect that needs to be considered in the construction process of new smart cities. At present, China still lacks mature applications and solutions in the field of data security in new smart cities. Based on the business characteristics and data applications of new smart cities, an idea is proposed from the perspectives of data security compliance, technology, and management, hoping to provide a useful reference for the industry to ensure data security in the construction of new smart cities.

    • The indicator system for city operation vital signs is an important way to grasp the dynamic development of city construction, explore the pain points of city development, and promote the digital reconstruction of city governance and the intelligence transformation of public service models. First, this paper conducts an in-depth discussion about existing research on the indicator system for city operation vital signs in China, and proposes a construction methodology consisting of four stages: demand analysis, framework building, indicator sorting, and practical application. Then, it builds a general indicator system covering 5 fields (primary classification), namely, livelihood services, government governance, industrial economy, ecological protection, and safety protection. The indicator system includes 27 secondary categories, 26 tertiary categories, and more than 500 specific indicators. At last, this paper puts forward suggestions on the construction and optimization of the indicator system.
