In order to reduce carbon emissions for sustainable development, we analyzed the impact of China's digital economy development on carbon emissions. Based on the panel data of 30 Chinese provinces from 2009 to 2019, we measured the level of development of China's digital economy using the entropy method. The relationship between the digital economy and carbon emissions was analyzed from multiple perspectives with the help of the fixed-effects model, the mediated-effects model and the spatial econometric model. The results indicate that the digital economy plays a significant inhibitory role in carbon emissions. In addition, the digital economy inhibits carbon emissions through the innovation effect and the industrial structure upgrading effect. Moreover, the digital economy exhibits a significant spatial spillover effect in dampening carbon emissions. Finally, there is regional heterogeneity in the direct and spatial spillover effect. The findings provide a basis for the digital economy to contribute to carbon emissions reduction and provide relevant policy references for achieving carbon neutrality and sustainable development.
为了实现可持续发展的碳减排目标，我们分析了中国数字经济发展对碳排放的影响。基于 2009 年至 2019 年中国 30 个省份的面板数据，我们使用熵值法衡量了中国数字经济的发展水平。借助固定效应模型、中介效应模型和空间计量经济学模型，从多个角度分析了数字经济与碳排放之间的关系。结果表明，数字经济对碳排放具有显著的抑制作用。此外，数字经济通过创新效应和产业结构升级效应抑制碳排放。同时，数字经济在抑制碳排放方面具有显著的空间溢出效应。最后，直接效应和空间溢出效应存在区域异质性。研究结果为数字经济助力碳减排提供了依据，并为实现碳中和和可持续发展提供了相关政策参考。
