【摘要】 在农业绿色转型发展驱动下，利用数字技术实现农药减量施用已成为解决农业污染与保障农产品质量安全的核心议题。由于受传统生产观念的影响，农户习惯追求高农药施用量以实现高产，农户农药减量施用在实践中面临重大难题。基于四川省537份农户调研数据，通过工具变量法分析数字化农机服务对农药减量施用的影响。研究结果显示，数字化农机服务对农户的农药减量施用具有显著的正向影响。中介效应结果揭示，数字化农机服务通过精准施药与及时决策促进农户农药减量施用。异质性分析表明，在政府规制情境下数字化农机服务对农户农药减量施用的影响更为显著。更多还原

【Abstract】 Driven by the green transformation of agricultural development, the use of digital technology to reduce pesticide use has become central to addressing agricultural pollution and ensuring the quality and safety of agricultural products. However, influenced by traditional production practices, farmers tend to overuse pesticides to boost yields, which poses a significant challenge to pesticide reduction. Based on the survey data of 539 farmers in Sichuan Province, this study analyzes the impact of digital agricultural machinery services on pesticide reduction by means of instrumental variable method(IV-Probit). The results show that digital agricultural machinery services have a significant positive impact on pesticide reduction among farmers. The intermediary effect analysis reveals that the services promote pesticide reduction through precision pesticide application and timely decision-making. Heterogeneity analysis indicates that the impact of the services on the reduction in farmers’ pesticide use is more significant under government regulation.更多还原
