The dynamic development process of urban resilience: From the perspective of interaction and feedback

Abstract

Abstract The urban system is gradually becoming a multi-level and multipolar network under the rapid development of information and communication technology. In the urban network, resources can flow orderly and realize optimal allocation, but the crisis also can spread and even exert an amplification effect. Focusing more on network resilience is essential for keeping the nexus safety. Thus, this paper develops a system dynamics model from multiple dimensions of urban resilience and uses a case study to illustrate its application. This model can reveal the dynamic development process of urban resilience and the interaction mechanism among different dimensions, which can help policymakers formulate classification policies and use them at the right time. The conclusions are as following: (i) This model is a widely applicable tool and its validity and application process are presented by the case study; (ii) Case study shows the development process of urban resilience is divided into three developing stages: rapid increase, slow increase, and rapid increase again; (ii) Case study shows that sub-network resilience has different characters. For example, the resilience of material and energy network is the most fast-growing part before 2020, but the resilience of governance network begins to have a leading position since 2021, which will play the most vital role to support the improvement of urban resilience in the future. (iii) Case study shows that each sub-network resilience has its sensitivity factors, which should become policy concerns and can maximize the output under the same input.
