Abstract / 摘要：
Due to global climate change and intensifying anthropogenic pollution, China confronts the dual challenge of controlling particulate matter 2.5 μm (PM<sub>2.5</sub>) pollution and reducing carbon emissions. Quantifying the characteristics of PM<sub>2.5</sub> concentrations and CO<sub>2</sub> emissions, as well as identifying the driving factors and synergistic effects of PM<sub>2.5</sub> reduction and CO<sub>2</sub> mitigation, are crucial steps in promoting sustainable urban development and achieving the Sustainable Development Goals (SDGs) in China. In this study, we selected 168 cities as our case-study, and quantified spatial characteristics of PM<sub>2.5</sub> concentrations and CO<sub>2</sub> emissions from 2015 to 2020 in China. Then we analyzed driving factors affecting the spatial heterogeneity of PM<sub>2.5</sub> reduction and CO<sub>2</sub> mitigation applying Multi-scale Geographically Weighted Regression (MGWR) model. By employing coupling coordination degree (CCD) model, we further detected the spatiotemporal evolution patterns of the synergistic effects between PM<sub>2.5</sub> reduction and CO<sub>2</sub> mitigation in key Chinese cities. The result showed that: (a) From 2015 to 2020, PM<sub>2.5</sub> concentrations experienced a significant reduction from 59.78 μg/m<sup>3</sup> to 49.83 μg/m<sup>3</sup>, while CO<sub>2</sub> emissions increased from 44.88 × 10<sup>6</sup> t in 2015 to 45.77 × 10<sup>6</sup> t in 2020; (b) Green economy efficiency (gee), government attention (gover), and environmental regulation (envir) demonstrate the most pronounced synergistic effect on pollution reduction and carbon mitigation, with the drivers exhibiting obvious spatial heterogeneity; (c) The overall coupling coordination level of PM<sub>2.5</sub> pollution and CO<sub>2</sub> emissions in China dropped from 0.49 in 2015 to 0.46 in 2020, and the coupling coordination grade in northern cities was notably higher than that in southern cities. The result enhances our understanding of spatiotemporal patterns of synergistic effects between PM<sub>2.5</sub> reduction and CO<sub>2</sub> mitigation, and provides the theoretical basis for policy decision-making to realize pollution decrease and carbon neutral and regional environment governance.
