As core regions for energy production and consumption, coal-resource-based cities play a pivotal role in achieving national emission reduction targets. This study examines panel data from 49 coal-resource-based cities in China from 2002 to 2022. Building on an analysis of the factors influencing carbon emission in resource-based cities, an extended STIRPAT model is developed, and a data-driven nonparametric additive regression model is employed to investigate the relationships among resource dependence, green technology innovation, and carbon emission. The results reveal that: The inhibitory effect of green technology innovation on urban carbon emission exhibited a threshold, with marginal emission reduction effects dynamically varying across urban development stages. Resource dependence demonstrated a path-locking effect, where highly dependent cities exhibited slower declines in carbon emission compared to their resource dependence. The national low-carbon pilot policies have significantly reshaped the relationship patterns between resource dependence and carbon emission in coal-resource-based cities. Specifically, pilot cities exhibited an M-shaped relationship between resource dependence and carbon emission, along with an N-shaped relationship between green technology innovation and carbon emission. In contrast, non-pilot cities demonstrated a flattened inverted U-shaped curve and a saddle-shaped curve for these respective relationships. Furthermore, the driving mechanisms of carbon emission influencing factors displayed distinct regional and lifecycle heterogeneities: Mature cities needed to surpass technological thresholds; growing cities had yet to see emission reduction effects; declining cities experienced weakened effectiveness of technology investment; regenerative cities faced the dynamic balance dilemma between low-carbon development and economic recovery, with carbon emissions exhibiting volatile non-linear trend; while cities in eastern, central, western, and northeastern regions all showed mismatched patterns between carbon emission and resource dependence. These findings provide a theoretical foundation for formulating differentiated urban emission reduction policies and promoting the low-carbon transition of coal-resource-based cities.
