基于2012—2022年全国30个省级行政单位的面板数据，运用空间杜宾模型，探究了数字经济对农业碳排放强度的影响。研究发现：数字经济发展对农业碳排放强度具有负向的空间溢出作用，且数字经济具有“示范效应”,其发展对周边区域的碳减排效果大于其对当地的影响；机制分析表明，数字经济通过提高农业绿色全要素生产率从而降低农业碳排放强度；异质性分析发现，数字经济对农业碳排放强度的影响具有明显的区域差距，我国中部与东部地区减排成效显著，西部地区尚不明显，需关注基础设施建设与本地化策略的结合。提出应强化数字农业政策引导与基础设施建设，构建农业绿色全要素生产率提升体系，针对地区差异实施差异化政策。

Based on the panel data of 30 provincial administrative units in China from 2012 to 2022,this paper explored the impact of digital economy on agricultural carbon emission intensity by using the spatial Durbin model.The results show that the development of digital economy has a negative spatial spillover effect on agricultural carbon emission intensity, and the digital economy has a "demonstration effect",and its carbon emission reduction effect on the surrounding region is greater than its impact on the local area.Mechanism analysis shows that digital economy reduces agricultural carbon emission intensity by improving agricultural green total factor productivity; Heterogeneity analysis shows that the impact of digital economy on agricultural carbon emission intensity has a significant regional gap, and the emission reduction effect in central and eastern regions of China is significant, while it is not obvious in western regions.Attention should be paid to the combination of infrastructure construction and localization strategies.It is proposed that policy guidance and infrastructure construction of digital agriculture should be strengthened, a system for improving agricultural green total factor productivity should be constructed, and differentiated policies should be implemented according to regional differences.
