Analysis of China's industrial network structure and its resilience from the sectoral perspective

The advancement of new industrialization and urbanization has accelerated the reconfiguration of industrial and supply chains, resulting in significant changes in the spatial organization patterns of industrial networks. Simultaneously, the increasing disturbances posed by various uncertain factors, along with the close interconnections between sectors, have, to some extent, accelerated the spread and spatial expansion of internal risks within the network. From a sectoral perspective, this article employs complex network theory and resilience theory to develop a comprehensive evaluation framework for assessing industrial network resilience. It reveals the evolution process of industrial network structural resilience from both static and dynamic perspectives based on risk disturbance shocks, providing new avenues for China's industrial network restructuring and industrial system optimization. The outcomes are as follows: From 2012 to 2022, China's industrial network structure became increasingly complex, with enhanced integration between the secondary and tertiary industries. Nevertheless, the overall correlation degree among various sectors remains low, with effective connections still primarily confined to local industrial networks. The core sector group within the overall industrial network comprises solely the wholesale trade and business services. Over time, the correlation paths and strengths between sectors have experienced slight expansion and improvement, and the comprehensive resilience level of both local and overall industrial networks has exhibited an increasing trend. The growth in static resilience is evident in the significant enhancement of transitivity and cohesion within the interconnected networks of the secondary and tertiary industries. The stability of the industrial structure is a key factor in enhancing the level of dynamic resilience. The article also endeavors to propose recommendations for optimizing industrial structure from a network perspective.
