数字金融工具的广泛应用有利于缓解碳排放压力，为“双碳目标”的加速实现提供了动力。本文基于 2011-2021 年 30 个省份的面板数据集，采用双向固定模型、中介效应模型以及空间杜宾模型分析数字金融对碳排放的影响效应。研究发现： 数字金融的发展对碳排放强度有显著的抑制作用；数字金融能够通过促进技术进步来降低碳排放；空间溢出效应表明数字 金融对邻近地区的碳排放强度具有正向空间溢出效应。据此提出相应建议以促进碳减排。

The widespread application of digital financial tools is beneficial for alleviating carbon emission pressures and providing impetus for accelerating the achievement of the "dual carbon goals". Based on the panel data set of 30 provinces from 2011-2021, in this paper two-way fixed model, mediation effect model and spatial Durbin model were used to analyze the impact of digital finance on carbon emissions. Research has found that the development of digital finance has a significant inhibitory effect on carbon emission intensity; digital finance can reduce carbon emissions by promoting technological progress; the spatial spillover effect indicates that digital finance has a positive spatial spillover effect on the carbon emission intensity of neighboring regions. Based on this, corresponding suggestions were proposed to promote carbon reduction. Keywords: digital finance; carbon emission intensity; spatial effec
