Abstract
Ports are both the start and end points of shipping, they are connected by shipping routes, thereby forming a port shipping network that connects global industries and supply chains. Each port node has specific functions within the network, while its capacity to resist interference differs from that of other ports; consequently, when encountering external shocks, ports are not affected equally. Therefore, this paper proposes the concept of port node resilience from the perspective of the shipping network. This is achieved by analyzing the literature on regional, urban, and network resilience. Thereafter, by fully considering the complexity of port nodes' linkages, as well as their attributes vis-à-vis the shipping network, a three-dimensional (structure, function, and location) econometric model of port-node resilience is constructed. By examining data from China's container ports for the years 2008 and 2018, this study analyzes port nodes' resilience characteristics and the differences in space. The results indicate that the studied port nodes' resilience index presents the characteristic of clustering. Further, the average resilience index increased from 0.25 (low) to 0.43 (medium). The differences in port nodes' regional resilience narrowed, while their absorption and transformation capacity improved when facing external interference.
