Based on the construction of a measurement index system for the coupling coordination of the perspective of “carbon reduction and pollution control” and “greenery expansion”, by using the coupling coordination model to calculate the coupling coordination of carbon reduction, pollution control, and greenery expansion in 273 prefecture level cities in China from 2014 to 2023, followed by an inquiry into the spatiotemporal evolution pattern, as well as an exploration of its improvement strategy with fsQCA method adopted. The research results indicate that, from the perspective of the overall national level during the sample period China’s overall carbon reduction, pollution control, greening and economic growth coupling coordination shows a stable upward trend; the eight major comprehensive economic zones. the coupling coordination degree of carbon reduction, pollution control, and greenery expansion in each region converges in the same direction. The regional differences in the coupling coordination degree of carbon reduction and pollution control in China are mainly due to regional discrepancies, with the differences characterized with strong spatial features. As for each spatial level, regions at different levels generally maintain their original hierarchical level and transition to higher levels. Effective ways to collaborate the promotion of carbon reduction, pollution control, carbonreduction, pollutioncontrol, greeningand economic growthinclude the three different strategies composed of such dominant factors as population density, energy efficiency, and environmental regulation level.
