城市降碳减污协同效应评估及其影响因素研究OACHSSCD

Cities serve as key spatial vehicles for the synergistic enhancement of carbon reduction and pollution control.Promoting urban green transition through carbon and pollution reduction represents a vital pathway to achieving modernization characterized by hu-man-nature harmony.Based on panel data from 2010 to 2022 covering 30 cities within this corridor,and employing the coupling coor-dination degree model,ordinary least squares(OLS),and geographically and temporally weighted regression(GTWR)model,it system-atically analyzes the evolutionary patterns and influencing factors of the synergistic effect between carbon reduction and pollution con-trol.The findings reveal that:① Pollutant emissions decrease significantly while CO2 emissions grow slowly;the synergy between carbon reduction and air pollution control remains at low levels with noticeable fluctuations,lacking a stable enhancement mechanism;② Re-gional synergy effects show significant spatial variation,with high emission areas concentrated in economically developed cities relying on coal-based energy structures;③ Total energy consumption,energy structure,and urbanization rate are the main factors affecting the carbon-pollution reduction synergy in World-Class Clean Energy Corridor cities.Based on these conclusions,the study proposes poli-cy recommendations to enhance urban carbon-pollution reduction synergy across dimensions such as differentiated policy design,opti-mized energy structure,and green industrial transformation.
