期刊：《Sustainability》.2026(4)

摘要：Under the coordinated implementation of the “dual carbon” goals and digital rural development strategy, digital technology has become a critical support for solving key problems in agricultural carbon reduction and advancing the green and low-carbon transformation of agriculture. Based on panel data from 31 provincial-level regions in China from 2010 to 2023, this study uses the fixed-effect model, mediating the effect model and threshold effect model to systematically examine the impact and transmission mechanism of digital technology on agricultural carbon emission intensity. The results show that: (1) Digital technology markedly lowers agricultural carbon emission intensity, and this conclusion remains steady after endogeneity correction and robustness checks. (2) Digital technology reduces emissions through two core channels: enhancing environmental regulation to constrain high-carbon behaviors via precise monitoring, and improving agricultural socialized services to promote intensive production and lower the adoption threshold of low-carbon technologies. (3) The emission reduction effect of digital technology exhibits a threshold characteristic related to agricultural industrial agglomeration, with the marginal effect of emission reduction showing an increasing trend as the agglomeration level rises. (4) The carbon reduction effect of digital technology shows obvious heterogeneity across grain production functional zones. The inhibitory effect is significant in major grain-producing areas and grain production–consumption balance areas, but not significant in major grain-consuming areas. (5) The carbon reduction effect also presents heterogeneity under different topographic relief conditions. The effect is significant in low-relief areas but not significant in high-relief areas, because complex terrain restricts the construction of digital infrastructure and large-scale application of digital technologies, which further reflects the regulatory role of natural geographical conditions. Accordingly, this paper proposes to strengthen the empowering role of digital technology in the green transformation of agriculture, attach importance to regional coordination and differentiated policy design, and comprehensively improve the capacity of agricultural carbon emission reduction and sequestration. Therefore, it is imperative to strengthen the enabling role of digital technology in the green transformation of agriculture, attach importance to regional coordination and differentiated policy design, and comprehensively enhance the capacity of agriculture for carbon emission reduction, sequestration and sustainable development.

在“双碳”目标与数字乡村战略协同推进的背景下，数字技术成为破解农业减排瓶颈、推动农业绿色低碳转型的关键支撑。本文基于2010—2023年中国31个省、自治区、直辖市（除港、澳、台）数据为研究样本，综合运用固定效应模型、中介效应模型与门槛效应模型，系统探究数字技术对农业碳排放强度的影响及作用机制。结果表明：(1)数字技术对农业碳排放强度具有显著且稳健的抑制作用，这一结论经内生性处理与多重稳健性检验后依然成立。(2)数字技术通过两条核心路径实现碳减排，一是强化环境规制水平，借助精准监测与多元规制协同约束高碳行为，二是提升农业社会化服务水平，通过整合低碳资源与降低技术采纳门槛推动生产集约化转型。(3)数字技术的减排效应存在农业产业集聚门槛特征，随着集聚水平提升，减排边际效应呈递增态势。(4)数字技术的碳减排效应存在显著的粮食生产功能区异质性，在粮食主产区与产销平衡区抑制效应显著，而在粮食主销区未呈现统计意义上的显著关联。(5) 数字技术的碳减排效应存在显著的地形起伏异质性，在地形起伏较低地区抑制效应显著，而在地形起伏较高地区则不显著，复杂地形约束了数字基建落地与技术规模化应用，进一步揭示了自然地理条件对减排效应的调节作用。因此，应强化数字技术对农业绿色转型的赋能作用，注重区域协同与差异化政策设计，全面提升农业减排固碳能力。
