Abstract：
Air pollution is a challenge for many cities. The digital economy enhances support for environmental pollution management, while the mechanisms and scaling heterogeneity remain unclear. This study explored the contribution of digital economy development to PM2.5 concentrations control in China and driving mechanisms in different economic subregions and urban agglomerations. Results show that the spillover transfer effect on air pollution mitigation far exceeded the direct effect at different scales. At the national scale, the air pollution mitigation effect of digital economy was mainly through empowering industrial structure optimization and green technology innovation, while it also affected economic subregions and urban agglomerations through varying scenario combinations of pathways with structural optimization, green production, resource allocation, and technology innovation. Research findings provide support for cross-regional joint management strategies of digital economy and air quality and designing regionally differentiated pollution control pathways in the digital economy dimension.
摘要：
空气污染是许多城市面临的挑战。数字经济增强了对环境污染管理的支持,虽然机制和尺度异质性仍不清楚。本研究探讨了数字经济发展对中国PM2.5浓度控制的贡献以及不同经济分区域和城市群的驱动机制。结果表明，在不同尺度下，溢出转移对空气污染缓解的影响远远超过直接影响。在全国范围内，数字经济的大气污染缓解效应主要通过赋能产业结构优化和绿色技术创新,虽然它也通过路径与结构优化的不同情景组合影响了经济次区域和城市群，绿色生产,资源分配,和技术创新。研究结果为数字经济和空气质量的跨区域联合管理策略以及在数字经济维度上设计区域差异化的污染控制路径提供了支持。
