The reduction of haze and carbon emissions is extremely important for promoting sustainable development, improving air quality, enhancing health, and mitigating climate change. However, there is not enough research available on the impact of fiscal decentralization in China on the management of carbon and haze reduction. In order to thoroughly examine the effects of Chinese-style fiscal decentralization on the synergy between haze reduction and carbon reduction in different provinces, this study utilizes a dynamic spatial panel Durbin model using Han-Phillips Generalized Method of Moments (GMM) estimation and a multi-scale geographically and temporally weighted regression model. Our findings indicate that the eastern region consistently takes the lead in reducing haze and achieving carbon synergy. Fiscal technology decentralization has a direct positive impact and spatial spillover effect on carbon haze synergy with significant inverted U-shaped characteristics. These effects primarily arise from the promotion of technological innovation through fiscal technology decentralization. Furthermore, the influence of decentralizing fiscal technology expenditures on the degree of synergy between haze mitigation and carbon reduction varies significantly across China's provinces, both spatially and temporally. This entails promoting coordination between fiscal decentralization and policies related to haze and carbon emission reduction and encouraging information sharing, technology exchange, and collaborative projects between different regions to create a synergistic linkage effect. This will help achieve joint development and environmental protection goals in all regions. The discoveries carry significant consequences for directing the synchronized administration of haze and carbon and can serve as a solid basis for governmental decision-making aimed at enhancing air quality and attaining carbon neutrality through collaborative actions and policies.
减少雾霾和碳排放对于促进可持续发展、改善空气质量、增进健康以及缓解气候变化极为重要。然而，关于中国财政分权对碳减排和雾霾治理的影响，现有研究尚不充分。为了深入考察中国式财政分权对不同省份雾霾减排与碳减排协同效应的影响，本研究采用了动态空间面板杜宾模型，运用汉-菲利普斯广义矩估计法（GMM）进行估计，并构建了多尺度地理加权和时间加权回归模型。我们的研究结果表明，东部地区在雾霾减排和实现碳协同效应方面始终领先。财政技术分权对碳霾协同效应具有直接的正向影响和空间溢出效应，呈现出显著的倒U形特征。这些效应主要源于财政技术分权对技术创新的促进作用。此外，财政技术支出分权对雾霾治理与碳减排协同程度的影响在我国各省份之间存在显著的时空差异。这就需要促进财政分权与雾霾和碳排放减排相关政策之间的协调，鼓励不同地区之间的信息共享、技术交流和合作项目，以形成协同联动效应。这将有助于实现各地区的共同发展和环境保护目标。这些发现对于指导雾霾和碳排放的同步治理具有重要意义，并可为政府通过协同行动和政策提高空气质量及实现碳中和的决策提供坚实依据。
