The Dynamic Improvement Mechanism of Urban Resilience

Abstract

The study results will be summarized as the following points: Point one, the growth of urban resilience is categorized into three periods. In the first period (1-2 year), urban resilience has faster growth, and the growth rate exceeds 10%, then the growth rate slows down (<7%) in the second period (3-8 year) and finally increases again (7%~8%) in the third period. Point two, the subsystems’ resilience plays distinct roles in the growth of generic resilience. For example, in the first period, the resilience of energy material network dominates the increasing of urban resilience followed by the resilience of governance network, the resilience of infrastructure network, and the resilience of socio-economic network. But in the second period, the resilience of energy material network slows down while the other subsystems' resilience overgrew. In the third period, the resilience of socio-economic network starts to play a critical role in the increase of urban resilience.
