The digital economy is a crucial focus for realizing the transformation of old and new kinetic energy in China. It is widely integrated with various fields of the economy and society, constantly providing a new dynamic mechanism with synergetic control of environmental pollution and carbon emissions (SCEPCE). Based on panel data from 292 prefecture-level cities in China from 2011 to 2021, this study discusses the spatial effects and mechanisms of the digital economy on the coordinated control of pollutants and carbon emissions. The study found that: (1) The digital economy has direct and indirect influences on the coordinated control of pollutants and carbon emissions. The digital economy can drive reductions in pollutants and carbon dioxide emissions by upgrading industrial structures and transforming energy structures. (2) Green innovation plays an active regulatory role in the digital economy and structural optimization, particularly in the context of SCEPCE. This interference helps mitigate the impact of the digital economy on pollution and carbon emissions. (3) The digital economy has a significant spatial spillover effect on the coordinated control of pollutants and carbon emissions. (4) The influence mechanism of the digital economy on pollution reduction and carbon reduction synergy exhibits geographical heterogeneity, resource endowment heterogeneity. To enhance the synergy of pollution reduction and carbon reduction, it is essential to bolster support and optimise the digital economy at various levels. This includes reinforcing regional balance, considering spatial spillover effects, and enhancing the leading role of developed cities in the region.
数字经济是实现中国新旧动能转换的关键着力点。它广泛融合于经济社会的各个领域，不断为环境污染与碳排放协同控制（SCEPCE）提供新的动力机制。本文基于 2011 年至 2021 年中国 292 个地级市的面板数据，探讨了数字经济对污染物与碳排放协同控制的空间效应及作用机制。结果表明：（1）数字经济对污染物与碳排放协同控制具有直接和间接影响，通过产业结构升级和能源结构转型驱动污染物和二氧化碳减排；（2）绿色创新在数字经济和结构优化中发挥了积极的调节作用，特别是在 SCEPCE 背景下，这种干预有助于减轻数字经济对污染和碳排放的影响；（3）数字经济对污染物与碳排放协同控制具有显著的空间溢出效应；（4）数字经济对减污降碳协同的影响机制具有地理异质性和资源禀赋异质性。为了增强减污降碳协同效应，需要在各个层面上加强对数字经济的支持和优化，包括加强区域平衡、考虑空间溢出效应，以及增强区域内发达城市的引领作用。
