Resource-exhausted cities face the dual pressures of ecological degradation and economic stagnation, making the achievement of synergistic development between high-quality economic growth and ecological resilience a core issue for regional sustainability. To clarify their coordination dynamics and response mechanisms, this study examines typical resource-exhausted cities in China’s Northeast Old Industrial Base, this study adopts an integrated approach combining comprehensive evaluation model, coupling coordination model, and panel vector autoregression (P-VAR) to analyze the spatial differentiation characteristics, synergistic evolution pathways, and interactive response mechanisms of economic development quality and ecological resilience from 2000 to 2020. The results indicate that: (1) Resource-exhausted cities exhibited a three-stage growth pattern of “medium-high-low” in economic development quality, while ecological resilience underwent an evolution from initial suppression to subsequent enhancement. Their coupling coordination level improved from basic dissonance (0.462) to basic coordination (0.631). (2) Resource-exhausted cities exhibited a gradient pattern where economic development quality was led by “dual-core leadership from coastal and border cities, coupled with the collapse of single-resource-dependent cities”, whereas ecological resilience displayed a“high in the south, low in the north, and stronger in comprehensive cities than in industrial-mining cities”structure. The coupling coordination degree exhibited a north-south divergence with a trend toward polarization. (3) A dynamic asymmetric response exists between economic development quality and ecological resilience in resource-depleted cities. Economic shocks exert a significant negative effect on ecological resilience, while ecological resilience shocks only cause a short-term, marginal suppression of economic development quality. (4) A pronounced asymmetric interaction mechanism exists between economic development quality and ecological resilience in resource-depleted cities. Fluctuations in ecological resilience are primarily driven by its own inertia, whereas economic development quality is driven by endogenous factors. In response, solutions and strategies are initially proposed in three areas: addressing gaps in high-quality economic development, strengthening the ecological resilience network, and formulating differentiated policies.
