Combined with the theory of digital twin technology and the construction practices of digital twin cityies, we further refined the connotation, 4 technical characteristics, 3 visions, 9 elements of digital twin city, proposed the “4 + 5” digital twin city framework, analyzed the three major challenges of digital twin cities that need to be strengthened in rational understanding, improved in data governance and explored in sustainable business model, and put forward strategies and suggestions of the development of digital twin cities for governments and enterprises.
From the perspective of feedback system, this paper introduces the concept of “entropy”, which describes the degree of system order, into the construction and evaluation of smart cities, and constructs its system framework model. Through the system dynamics modeling method, the smart city is modeled, which is abstracted as the data collection, transmission and application system, and is quantitatively described in combination with the new smart city evaluation criteria. By modeling and analyzing the smart city evaluation data of a city, the feasibility and effectiveness of the model method are verified.

Digital government is the strategic plan and systematic deployment for the State Council to build a new situation during the 14th Five Year Plan period. Since its establishment, Shanghai Big Data Center has continued to make iterative breakthroughs and innovations in government digital infrastructure construction, operation and management, becoming a model of government digital transformation. This paper analyzes and introduces the key points of the construction of integrated operation of Shanghai digital government information infrastructure services, and summarizes and shares some key experiences in the construction of integrated operation.
The wide application of Internet of Things technology has strongly promoted the construction of smart cities. By settling the common needs of urban governance, building a digital city perception base that supports ubiquitous device access, data storage analysis, reverse control and other general capabilities can better integrate the upper layer Internet of Things applications and accelerate the urban digital transformation. In terms of device access, this paper proposes a new data model and device physical model based on device characteristics, and constructs a storage system of distributed Internet of Things platform based on the data model and device physical model. In terms of device control, it supports cloud control and local control. Based on the digital city perception base proposed in this paper, smart city applications such as smart epidemic prevention, smart water conservancy and smart fire protection are constructed, effectively promoting the urban digital transformation.
Under the background of new infrastructure, the digital transformation of community is a natural and inevitable trend, which faces many opportunities and challenges. Combined with the author’s practice of smart community construction in recent years, this paper summarizes effective measures and approaches to promote the digital transformation of communities, and forms a systematic methodology, which plays an important role in improving the level of community governance, optimizing public services, and promoting convenience and benefits for the people. With the continuous investment in new infrastructure, community digitalization is speeding up to the trend of intensive construction, fine service, efficient operation, and is gradually stepping onto a market-oriented and sustainable development road.
Digital twin is the key to promote the digital transformation of urban governance. This paper introduces the definition and key elements of digital twin, studies the digital transformation of technology support governance and the operation of enabling cities, further analyzes the problems based on existing practices, and puts forward optimization suggestions. It is suggested to improve the urban digital governance capability and effect from the aspects of top-level design and overall planning mechanism, formulation of field standards and specifications, exploration of whole industry chain cooperation, high-value application scenarios, establishment of long-term operation mode, etc.
By sorting out business characteristics, overall architecture and construction, this paper summarizes development status of comprehensive transportation data brain. Then, it analyzes two major changes of comprehensive transportation data brain in the new era: management transforms from data management to data asset management, and application transforms from data statistics to data intelligence. Finally, The article proposes constructive ideas, overall architecture, horizontal and vertical logical architecture for comprehensive transportation data brain.
The digital transformation of elderly care is an important part of urban digital transformation. By sorting out the connotation and development status of the digital transformation in the field of elderly care, this paper analyzes issues such as the digital foundation of the elderly care, digital application construction of the elderly care, and digital elderly care management. It delivers countermeasures and suggestions to applications creation, digital adaptation for aging, and elderly care service supervision for promoting digital transformation in the field of elderly care.
After 2020, the construction and cultivation of data element market has become the main task of data related local legislation. The data regulations issued by Shenzhen and Shanghai are particularly significant in this regard. The advanced exploration of local legislation is beneficial to guide the construction of data element market system, respond to the needs of economic development and promote future national legislation. However, it is necessary to solve key problems such as how to understand and locate the property attribute of data, how to allocate benefits of data access and income, and how to protect personal information. The EU's legislative ideas on data access rights are worthy of our reference. The next important work is the after-legislation evaluation, to summarize experience in time, and to ensure the legal system can always promote the development of digital economy.
The 2022 amendment to the Anti-Monopoly Law of the PRC (AML) makes minor modifications to the 2008 AML, in response to challenges raised by the platform economy. Through introducing a new article (Article 9) to the General Chapter and revising previous article against abuse of dominant market position (Article 22(2)), the 2022 AML provides explicit legal basis for the Chinese competition authority to directly respond to the platform economy. Articles on the new legislative purpose (“encouragement of innovation”), hub-and-spoke arrangement, review of mergers having not met the notification threshold, and the classification and grade mechanism in relation to merger control are indirect responses to the platform economy. To more efficiently and effectively implement the 2022 AML, Chinese competition authority should improve supporting guidelines and regulations, especially cautious application of technical concepts, to guarantee a good match between anti-monopoly regime and the development of platform economy. Positive roles played by capitals should be respected when controlling the expansion of capitals through merger control and other anti-monopoly tools. To better coordinate the relationship between anti-monopoly rules, and data protection, consumer right and interest protection rules, China should think twice before introducing provisions against exploitative abuse of dominance.
In order to further strengthen the role of traditional Chinese medicine(TCM) in ensuring people's lives and health, experts domestic and abroad begin to gradually explore the application of digital technologies in the traditional Chinese medicine industry. At present, the digitalization of TCM diagnosis, TCM prescription, TCM treatment, TCM education and other related areas has achieved fruitful results.Breakthrough progress has been made in technology. Some products have been applied in a certain range. However, there are still many problems in the digital development of traditional Chinese medicine, which need to be further strengthened from the top-level strategy, new infrastructure, technology supply and application deployment, so as to promote the high quality of the traditional Chinese medicine industry and escort the great rejuvenation of the Chinese nation.
