Resilience Evolution of Dongguan Industrial Network Based on Enterprise Connections
Abstract
Currently, global uncertainties and instabilities are increasing significantly. Therefore, research on the evolution of urban industrial network resilience is essential for strengthening the ability of urban industries to withstand major events. This study constructs a network of firms using data on corporate headquarters and branches in Dongguan registered between 1979 and 2020. It analyzes the evolution of urban industry network resilience through interruption simulations and complex network invulnerability. The study empirically examines the resilience of Dongguan's industrial network, focusing on single-node resilience, overall network resilience, and regional network resilience. The results indicate the following: (1) In the single-node simulation attack of the Dongguan industrial network, the impact of urban core nodes on network resilience gradually weakens. The differences between urban core nodes and general town nodes continue to diminish, and the network's resistance to single-node disruptions tends to stabilize. (2) Compared to random attacks, deliberate attacks can cause networks to collapse faster. However, as Dongguan's industrial networks evolved toward a multi-center structure, the impact of targeted attacks on network resilience gradually decreased. (3) The resilience of Dongguan's industrial network to Shenzhen is lower than that to Guangzhou. However, the strength of enterprises inside and outside the city tends to balance, and the resilience level of the regional network is gradually stabilizing. (4) Overall, the evolution of industrial network resilience in Dongguan is characterized by a shift from a single-center network with a low level of resilience to a multi-center network with a higher level of resilience. The innovation of this research lies in two key areas: First, it provides valuable contributions to related research on urban network resilience and industrial resilience by introducing the concepts and methods of interruption simulation and complex network invulnerability. Second, by conducting a long-term, continuous analysis of network resilience, this study explores the evolution of network resilience from a dynamic perspective, offering a fresh viewpoint for existing static network resilience studies. Therefore, based on this research, the study suggests that constructing a multi-centric development structure and strengthening coordination among industries at various nodes can effectively improve the resilience level of the industrial network. Meanwhile, it is important to focus on balancing internal and external forces in the development of urban industries to avoid excessive interference from external industries on local urban industries.
