摘　　要：科技创新作为农业强国建设的核心支撑力量,对全面实现乡村振兴和农业绿色低碳发展具有重要影响。论文基于2012—2021年黄河流域面板数据,构建空间杜宾模型、中介效应模型、调节效应模型,对农业科技创新和农业碳排放强度的关系进行实证分析。结果表明:(1)研究期内,黄河流域农业科技创新水平稳步提升,呈现“西低东高”的连片式空间分布特征;农业碳排放强度上下波动后下降,呈现“西高东低”的连绵式空间分布特征。(2)整体来看,农业科技创新对农业碳排放强度具有显著的抑制作用。分流域来看,农业科技创新对黄河下游的碳减排效应最强,中游次之,上游较低的农业科技创新反而促进农业碳排放强度提升。(3)农业科技创新能通过降低农业化学化水平和提高农业机械化水平的两条途径降低农业碳排放强度。其中,财政支农在这两条途径中发挥调节作用。Technological innovation,serving as the central pillar for the construction of an agricultural powerhouse,plays a pivotal role in the comprehensive realization of rural revitalization and the green and low-carbon development of agriculture.Drawing from panel data of the Yellow River Basin from 2012 to 2021,this study employs the spatial Durbin model,mediation effects,and moderation effects models to empirically examine the relationship between agricultural technological innovation and agricultural carbon emission intensity.Our findings indicate that:(1) Throughout the study period,the level of agricultural technological innovation in the Yellow River Basin has steadily increased,exhibiting a contiguous spatial distribution characterized as “low in the west and high in the east”.Concurrently,the agricultural carbon emission intensity,after experiencing fluctuations,has demonstrated a decline,presenting a continuous spatial distribution pattern of “high in the west and low in the east”.(2) On the whole,agricultural technological innovation significantly suppresses the agricultural carbon emission intensity.From a basin-specific perspective,the carbon reduction effects of technological innovation are most pronounced in the lower reaches of the Yellow River,followed by the middle reaches.Conversely,technological innovation in the upper reaches tends to promote agricultural carbon emissions.(3) Agricultural technological innovation can reduce agricultural carbon emission intensity by decreasing the level of chemical use in agriculture and enhancing agricultural mechanization.Within this context,fiscal support for agriculture acts as a moderator in these two channels.
