【摘要】 当前我国城乡收入相对差距在缩小，但依旧较为显著。农业数字化为缩小城乡收入差距提供了新路径，并在农业现代化和高质量发展中发挥关键作用。据此，研究基于2012—2022年中国30个省份的面板数据，利用双向固定效应模型、中介效应模型和空间杜宾模型，系统探究农业数字化对城乡收入差距的影响机制与空间溢出效应。研究发现：农业数字化能够显著缩小城乡收入差距，促进技术进步和提高劳动生产效率在其中发挥了中介作用；异质性分析表明，相较于中部地区，在东、西及东北地区农业数字化展现优化城乡收入差距的作用，且分位数回归显示该效应在城乡差距最小的地区相对较弱；在农业数字化的空间溢出效应分析中发现，农业数字化不仅改善本地区城乡收入，也改善周边地区城乡收入差距。综上，基于研究发现，文章提出加快落后区域数字基础设施建设，强化技术扩散机制，提升农业数字化的空间联动效能，充分发挥农业数字化水平在城乡收入趋同方面的优势。更多还原

【Abstract】 Currently, the relative urban-rural income gap in China is narrowing but remains significant. Agricultural digitalization provides a new path for narrowing the urban-rural income gap and plays a key role in agricultural modernization and high-quality development. Based on this, using panel data from 30 provinces in China from 2012 to 2022, this study systematically investigates the influencing mechanisms and spatial spillover effects of agricultural digitalization on the urban-rural income gap by employing two-way fixed-effects models, mediation models, and spatial Durbin models. The findings reveal that: agricultural digitalization can significantly reduce the urban-rural income gap, with promoting technological progress and increasing labor productivity playing mediating roles. Heterogeneity analysis indicates that, compared to the central region, agricultural digitalization shows an optimizing effect on the urban-rural income gap in the eastern, western, and northeastern regions, and quantile regression shows this effect is relatively weaker in areas with the smallest urban-rural gap. The analysis of spatial spillover effects finds that agricultural digitalization not only improves the urban-rural income situation in the local region but also reduces the urban-rural income gap in neighboring regions. In conclusion, based on the research findings, the article proposes accelerating the construction of digital infrastructure in lagging regions, strengthening technology diffusion mechanisms, enhancing the spatial linkage effectiveness of agricultural digitalization, and fully leveraging the advantages of agricultural digitalization in achieving urban-rural income convergence.更多还原
