中国城市群网络系统的时空演进及韧性评估
Spatiotemporal Evolution and Resilience Assessment of China's Urban Agglomeration Network System
摘要
Abstract
Enhancing the resilience of urban agglomerations is the key for regions to respond to changes in the external envi-ronment and achieve sustainable and high-quality development.This paper decomposes the multi-regional input-output table at the urban scale in China by using the value chain decomposition method,deconstructs the"dual circulation"structure of 12 urban agglomeration systems from 2012 to 2022,and constructs the"dual circulation"network of urban agglomerations.On this basis,the quasi-natural experiment-interruption simulation method is adopted to simulate the dynamic changes of the characteristics of the urban agglomeration network system under the impact of the external environment,and then evaluate the"dual circulation"re-silience level of each urban agglomeration network system.The findings are shown as the following:(1)In terms of the spatial topo-logical characteristics of urban agglomerations,the urban units within urban agglomerations usually form segmented agglomeration groups along provincial boundaries.(2)In terms of the overall network resilience of urban agglomerations,the overall network re-silience level of each urban agglomeration unit shows a continuous upward trend.(3)In terms of the network resilience of the inter-nal and external circulation subsystems of urban agglomerations,the resilience of the internal circulation subsystem is similar to that of the overall system with relatively small differences,while the resilience of the external circulation subsystem shows more significant differences.关键词
