  • 摘要: 持续推进科学施肥是实现稳粮保供和生态文明建设的有力支撑。为探寻数字乡村建设背景下促进我国农户科学施肥的有效策略, 本文基于湖北省水稻产区1256份农户调查数据, 利用Heckman两阶段模型, 从“采纳行为” 和“采纳程度”两个方面探讨了农技推广服务信息化对农户科学施肥技术采纳决策的影响; 并运用逐步回归法对农技推广服务信息化影响农户科学施肥技术采纳决策的作用机理进行剖析。研究发现: 1)农技推广服务信息化对农户的科学施肥技术采纳行为和采纳程度均存在显著的正向影响。2)农技推广服务信息化对农户不同类型科学施肥技术采纳行为的影响存在差异。相较于新型肥料施用技术, 农技推广服务信息化对农户采纳高效施肥技术的带动效应更大。3)农技推广服务信息化通过提高效益认知促进农户的科学施肥技术采纳行为, 通过降低风险认知促进农户的科学施肥技术采纳行为和采纳程度。据此, 本文提出要不断丰富信息化服务形式与内容、完善协同推广机制、通过个性化服务和精准推广提升农技推广服务效能等政策建议。
