“…The arguments for the inclusion, or exclusion of various cities (Wuhan v Changsha, Shenzen, Nanjing and Qingdao etc.) are discussed in China Economic Weekly (2017), which highlights the urban promotion by the leading members of some of these cities making the case for inclusion (see Yang, 2022). What is impossible to ascertain is the internal decision-making process and the nature of the economic and political criteria which are employed for evaluation.…”

“…The implications of these gradual additions is that the list of NCCs is not a final one and that some additional cities may be added in future. It is clear that the NCC designation is a valuable, sought-after one, and that a number of Chinese cities wish to become NCCs (Yang, 2022). But this raises two important questions.…”

This paper critically examines a recent innovation in Chinese urban policy: the designation of a new category of ‘National Central Cities’ (NCCs). These cities, of which there are currently nine, are meant to play a key role in economic modernisation and national economic development. But, despite their undoubted importance, their precise role, definition and function and their basis of designation is unclear. The paper argues first that the underlying, but implicit, theoretical rationale is growth pole theory and that the cities are meant to play a major role in the diffusion and ‘radiation’ of economic growth and other forms of development in their regional hinterlands. The paper also examines the geographical distribution of NCCs in China and looks at their ranking compared to other cities in terms of a number of different indicators such as GDP and population and asks why some cities have been chosen and not others. What is the basis of NCC designation? Finally, it speculates on the future number and distribution of NCCs, the competition for new designation and the possible benefits designation may confer.

“…The particles were then given the unfrozen soil thermodynamic fine view parameters as in Table 2, and the boundary wall was set to a fixed 22 • C. According to the actual brine cooling curve of the project (Figure 2) in the freezing tube temperature of the brine temperature set, the beginning temperature of the ground is set to 22 • C. (4) Thermal coupling calculation: The thermal coupling calculation module is enabled by the command "set thermal on mechanical on". The inclusion of a judgment statement enables the particles to be given a coefficient of frost heave (thaw settlement) if the temperature of the soil particles meets the conditions for frost heave (thaw settlement) [32][33][34][35]. The specific calculation process is shown in Figure 5 below.…”

Analyses of the Ground Surface Displacement under Reinforcement Construction in the Shield Tunnel End Using the Artificial Ground Freezing Method

et al. 2023

There are stringent requirements on the vertical movement of a ground surface when using artificial ground freezing method to reinforce a shield tunnel in a city. This paper focused on the tunnel of Nanjing Metro Line Two between Yixianqiao and Daxinggong. Based on the discrete element thermo-mechanical coupling theory, the horizontal freezing reinforcement project was numerically simulated. The numerical results of the soil temperature field and displacement field are approximately compatible with the field measurements. When the tunnel was frozen for 40 days, an effectively frozen soil wall was created and satisfied the construction requirements. During the freezing construction, both frost heave and thaw settlement obviously occurred. Above the tunnel, the vertical deformation of the ground surface was symmetrical about the center of the tunnel and decayed towards the ends. The maximum vertical displacement of ground surface frost heave was 8 mm, and the maximum vertical displacement of ground surface thaw settlement was 18 mm. Increasing the depth of the tunnel embedment can result in a decline in ground surface displacement. The study serves as a viable means of predicting ground surface displacements.

“…On the basis of “digital environmental protection,” the “environmental protection wisdom” adds intelligent sensing system equipment in the front-end application, uses various information and communication technologies, and integrates the environment Internet of things through cloud computing, virtualization, and mainframe computers [ 7 ]. Building a new generation of network “smart” environmental protection systems integrating strong perception ability [ 8 ], intelligent processing ability, and comprehensive management ability provides more dynamic and accurate support for environmental management and decision-making, and digital environmental protection is the foundation of intelligent environmental protection. Compared with the traditional urban environmental governance mode, realizing the digitization and networking of environmental monitoring equipment is the basis of intelligent environmental protection.…”

Based on the perspective of digital finance and technological innovation, this paper analyzes its application in economic development, green economy, and sustainable development. With the continuous development of technological economy, methods such as artificial intelligence, Internet of Things, big data, and cloud computing become increasingly mature. Economic development is inseparable from the empowerment of technology. In this paper, firstly, we introduce the basic concepts and main forms of digital finance and technological economy and list the cutting-edge technologies including blockchain, VR, sharing economy, and other modes. Then, we analyze the application trend of technology economy. Finally, we analyze the examples of digital finance and technological innovation in detail, including tourism economy, digital marketing, sharing economy, smart city, digital healthcare, and personalized education, three hot topics of technology intersection and integration. In the end, we put forward prospects for the development of a digital economy, digital finance, and technological innovation.
