Resilience of Urban Network Structure in China: The Perspective of Disruption

In light of the long-term pressure and short-term impact economic technological globalization, regional urban resilience has become an important issue in research. As a new organizational form systems, networks generated by flow space emerged as popular subject By gathering 2017 data from Baidu search index, Tencent location service, social statistics, this study constructs information, transportation, among 344 cities China to analyze spatial patterns explore their structural characteristics perspectives hierarchy assortativity. Transmissibility diversity were used represent network structure interruption scenarios (node failure maximum load attack). The results show following: at prefecture level higher exhibit dense pattern distribution east sparse west; however, there are significant differences terms order transmissibility strong weak was economic, transportation. had nearly identical scores response nodes. Moreover, highly heterogeneous more likely cause shocks structure, owing its cross-regional links case disturbance. We identified 12 dominant nodes 93 vulnerable that can help accurately determine impetus behind resilience. capacity regions for resistance recovery be improved strengthening construction emergency systems risk prevention mechanisms.
