摘要:

目的 数字技术已成为推动粮食产业高质量发展的新动能，充分发挥数字要素在夯实粮食安全根基中的作用也已然成为新时期“三农”工作的重点。方法 文章基于2011—2021年中国省域面板数据，运用双向固定效应模型实证研究了农业数字技术发展对粮食绿色全要素生产率的影响。结果 （1）农业数字技术发展对粮食绿色全要素生产率提升具有显著促进作用。（2）异质性分析表明，农业数字技术发展的作用效果在政策支持力度大、自然资源禀赋高的地区发挥更充分。（3）机制分析表明，农业数字技术发展可通过对粮食绿色生产技术的效率改进和技术进步两条路径作用于粮食绿色全要素生产率。（4）进一步的门槛效应分析表明，农业数字技术发展对粮食绿色全要素生产率的促进作用因效率改进和技术进步的不同发展阶段呈现出非线性特征。结论 政府应科学引导数字技术向农业领域渗透融合，因地制宜发展农业数字技术，扎实推进跨区域粮食生产合作，并切实增强农业科技创新能力提升。

Abstract:

Digital technology has become a new driving force to promote the high-quality development of the grain industry, and giving full play to the role of digital elements in consolidating the foundation of food security has become the focus of "agriculture, rural areas and farmers" in the new era. Based on the provincial panel data of China from 2011 to 2021, this research empirical studied the influence of agricultural digital technology development on the green total factor productivity of grain by using the two-way fixed effect model. The results were showed as follows. The development of agricultural digital technology played a significant role in promoting the promotion of green grain total factor production. The heterogeneity analysis showed that the effect of agricultural digital technology development was more fully played in the areas with strong policy support and rich natural resources. The mechanism analysis showed that the development of agricultural digital technology could act on the green total factor productivity of grain through the efficiency improvement and technological progress of grain green production technology. Further threshold effect analysis showed that the promoting effect of agricultural digital technology development on the green total factor productivity of grain showed non-linear characteristics due to the different development stages of efficiency improvement and technological progress. Therefore, the government should scientifically guide the penetration and integration of digital technology into the agricultural field, develop agricultural digital technology in accordance with local conditions, steadily promote trans-regional cooperation in grain production, effectively enhance the innovation capacity of agricultural science and technology.
