| contents | Amid China's dual-carbon transition, the synergistic alignment of green finance with green-technology innovation is pivotal for co-controlling pollution and CO2 emissions. Using panel data for 266 Chinese prefecture-level cities over 2007-2023, We construct the coupling coordination index system of green finance and green technology innovation via a coupling-coordination model and systematically analyzes influencing mechanism of synergistic effect of pollution and carbon reduction. Four findings emerge.(1) The coupled-coordination significantly enhances the synergy, and energy efficiency plays a partial intermediary role in the relationship between the two.(2) The effect is heterogeneous: pronounced in the eastern and western regions, negligible in the central region, and stronger in non-resource-based and non-Yangtze River Basin cities.(3) A double-threshold model reveals a non-linear strengthening pattern as green-finance depth increases.(4) Spatial Durbin estimates show positive spillovers: the coupling of green finance and green technology innovation not only improves the level of local coordination, but also drives the improvement of environmental performance in adjacent areas. These results provide quantitative guidance for allocating green-finance resources, elevating green-innovation efficiency, and designing regionally coordinated mitigation policies. |
