摘要：    在中国同时面临“生态环境根本好转”和“碳达峰碳中和”两大挑战的现实背景下，探索数字经济作为经济高质量发展的新动力，能否有效推动减污降碳协同发展成为一项重要而迫切的议题。本文基于2011—2021年中国278个城市的面板数据，综合运用面板回归模型、中介效应模型和空间杜宾模型等，实证考察了数字经济对减污降碳协同发展的影响。结果发现，数字经济能够有效促进本地减污降碳协同发展，且该影响随着数字经济水平提升而逐渐增强。绿色技术创新在数字经济推动减污降碳协同发展中发挥中介作用。空间视角下数字经济对邻地减污降碳协同发展的空间溢出效应呈现出从“以邻为壑”到“以邻为伴”的变化（U型变化），且该溢出效应随地理距离增加而减弱，仅在100 km-400 km的地域内显著；其中，绿色技术溢出是导致空间溢出效应U型变化的重要机制。本研究为数字经济如何影响减污降碳协同发展提供了经验证据，也为区域间减污降碳协同增效的政策设计和实现路径提供了现实参考。

Abstract:    In the context of China facing the challenges of "fundamental improvement of ecological environment" and "carbon peak and carbon neutrality" simultaneously, whether the digital economy, as a new impetus for high-quality economic development, can effectively promote the synergistic reduction of pollution and carbon emissions (SRPCE) is an important issue that deserves to be explored in depth. Using comprehensively the panel regression model, the mediating effect model and the spatial Durbin model, this paper empirically examined the impact of the digital economy on the SRPCE based on the panel data of 278 Chinese cities from 2011 to 2021. The results showed that: (1) digital economy can effectively promote local SRPCE, and the effect gradually increases with the level of digital economy promotion; (2) Green technology innovation plays a mediating role in the facilitation of the digital economy on the SRPCE; (3) The spatial spillover effect of the digital economy on the SRPCE in neighbouring cities from a spatial perspective showed a change from "neighbour-beggar" to "neighbour-companion" (U-shaped change), and the spillover effect decreases with the increase of geographic distance, which is only significant within a geographical area of 100-400 km; and (4) green technology spillover is an important mechanism leading to the U-shaped change. This study will provide empirical evidence on how the digital economy influences the SRPCE, as well as a practical reference for the policy design and realization path for interregional synergies in pollution and carbon reduction.
