[Coupling Coordination and Spatial Correlation Network Structure of Economic Resilience and Ecological Resilience]

In the context of China's "dual-carbon" strategy and its pursuit of high-quality development， elucidating the synergy between regional economic resilience and ecological resilience is essential for simultaneously protecting the environment and sustaining economic growth. This study develops an integrated evaluation framework for economic and ecological resilience and employs a coupling coordination model to quantify their coordination. Integrating a gravity model with social network analysis， we reveal the spatiotemporal coupling characteristics and interaction-network structure of the economic-ecological system at national and regional scales. Between 2014 and 2023， the national coupling coordination index rose steadily while regional disparities narrowed， and the spatial pattern evolved from an "east-strong， west-weak" and "south-strong， north-weak" configuration toward a "multi-polar equilibrium." The spatial network structure transformed from point-to-point linkages to agglomerated networks， in which core regions played a pivotal driving role. Regions were classified into four block types-strong net spillover， weak net spillover， primary beneficiary， and bidirectional spillover-with increasingly complex and diverse transmission paths of coupling dynamics. This research deepens our understanding of the spatial evolution mechanisms of the economic-ecological system and provides a theoretical basis and decision-making guidance for harmonizing regional environmental governance with economic development.
