Has the Digital Economy Changed the Urban Network Structure in China?—Based on the Analysis of China’s Top 500 New Economy Enterprises in 2020

Abstract

The rapid development of the new generation of information technology makes digital enterprises and the digital economy important forces in promoting the sustainable growth of the world economy. Under the influence of the digital economy, the original urban network may undergo drastic changes. There have been studies that have arrived at conflicting conclusions. This paper primarily illustrates whether or not the digital economy has changed the urban network structure. China's digital economy is developing rapidly, becoming a new engine for the high-quality development of the Chinese economy. Therefore, this paper demonstrates the impact of China's digital economy on the urban network structure by using data from China's Top 500 New Economy Enterprises in 2020 and the headquarter–subsidiary ownership method. The results show that 1) China's urban network has changed significantly. Compared with APS enterprises and listed companies, the urban network of the digital economy has become more polarized, and Beijing has become the absolute control center. 2) Chinese cities have been reshuffled in the era of the digital economy. Beijing, Hangzhou, and Chengdu, with their industrial foundations in the digital economy, have performed better within the network. Simultaneously, some heavily industrialized cities, such as Wuhan, Shenyang, and Chongqing, have been declining due to the difficulties associated with transformation. 3) Although the digital economy has reshaped China's urban network structure to a certain extent, the original urban pattern still plays a dominant role in the new system. The network spatial pattern of dense east and sparse west still exists, and provincial capitals and subprovincial cities still play a more significant role in the network than ordinary cities. 4) Network diffusion is typically a hierarchical diffusion between core nodes. Geographical proximity has a low constraint on network diffusion, and subsidiaries expand outward through hierarchical diffusion.

Path to sustainable development: Does digital economy matter in manufacturing green total factor productivity?

“…At the meso‐industry level, the research of Roblek et al (2021) shows that industrial digitization in the digital economy is an effective way to enhance the competitiveness of manufacturing. Digital industry has a lasting effect on the social economy and will penetrate into all fields of the economy and society (Chen & Zhu, 2021; Landry, 2001). At the macroeconomic level, the digital economy can significantly improve the quality of exports (Yabo & Jie, 2022) and drive improvements in productivity (Tranos et al, 2021).…”

“…Alternatively, the digital economy builds inter‐organizational information systems through technical spillovers to achieve efficient exchange of digital information and low‐cost coordination methods. In the interaction of upstream and downstream industries, the use of industrial chains to integrate and optimize the entire economic system reduces the “friction” in search and transaction, reduces the cost of information communication, and breaks down barriers to information exchange, thereby further improving efficiency (Chen & Zhu, 2021). Therefore, Hypothesis 2a was proposed:H2a From the perspective of manufacturing GTFP decomposition, the digital economy can significantly promote manufacturing “technical efficiency.”Second, it is about the impact of digital economy on technical progress.…”

Mitigating information asymmetry to acquire venture capital financing for digital startups in China: The role of weak and strong signals

“…Due to its booming digital economy and distinctive regulatory environment, China serves as an appropriate context to investigate how digital ventures gain access to external financial resources. According to official data from the China Academy of Information and Communications Technology, China's digital economy was valued at $US 6.1 trillion in 2021, which accounts for 39.8% of its GDP growth (Chen, 2021). The rapid growth of China's digital economy brings vast opportunities to startups as well as competitive pressure to acquire external resources, in light of the ever-increasing number of novel digital startups and their extensive capital needs.…”

The Impact of the Digital Economy on China's Carbon Emissions

“…Chen et al (2022) divided digital economy into basic sector, integration sector and alternative sector, and comprehensively analyzed the structure and contribution of digital economy [35]. With the rapid development of digital economy, scholars gradually began to study the impact of digital economy development on industrial structure optimization (Su et al, 2021) [36], urbanization construction (Chen et al, 2022) [37] and green growth (Ren et al, 2022) [38] with the help of panel data model and Spatial Dubin Model. Focusing on the social effects of digital economy, the linkage between green economy and digital economy contributes to the coordinated development of urban economy and the improvement of people's sense of well-being, thus promoting the elimination of urban polarization and the gradual realization of sustainable development (Savchenko 2020) [39].…”
