Abstract:

Coupling and coordinated development of new infrastructure and regional resilience is an effective way to achieve new urbanization. This study constructs an evaluation index system for new infrastructure and regional resilience. Using a combination weighting and coupling coordination degree model, we measure the development index and coupling coordination level of new infrastructure and regional resilience across 31 provinces of China from 2013 to 2020. The Dagum Gini coefficient, spatial autocorrelation, and Markov chain are used to analyze spatial and temporal differences and evolution trend characteristics. The results reveal the following: (1) The new infrastructure and regional resilience development index are rising, with the coupling coordination state transitioning from mild imbalance to narrow coordination. (2) A spatial imbalance is observed in the level of coupling coordination; although the overall difference is decreasing, interregional differences remain the primary source of the overall disparity. (3) The coupling coordination level exhibits pronounced spatial agglomeration characteristics, mainly represented by high-value agglomeration areas in the east and low-value agglomeration areas in the west. (4) Coupling coordination tends to progress to high levels, although achieving leapfrog development remains challenging; high-value provinces exert a substantial positive spillover effect on neighboring provinces. This study examines the development status of new infrastructure and regional resilience, providing theoretical support and decision-making references for multiagent planning and management.

Key words: new infrastructure, regional resilience, coupling coordination degree, spatial differences, evolution trend
