摘　　要：农户作物营养强化技术采纳能否提高生产绩效,是促进作物营养强化技术扩散,进而改善人口营养健康、推动高附加值农业发展面临的重要现实问题。本文以营养强化小麦为例,采用豫冀陇晋四省606份农户调研数据,同时考量生产、消费和微量营养素缺乏水平,利用内生转换模型实证探究农户作物营养强化技术采纳能否以及多大程度提高农户生产绩效。结果表明:第一,农户作物营养强化技术采纳能够显著提高农户生产绩效。具体而言,控制农户自选择偏误后,农户作物营养强化技术采纳分别提高了6.81%的小麦亩产以及14.84%的小麦亩收入。第二,农户作物营养强化技术采纳对生产绩效的影响存在一定的区域异质性。第三,农户作物营养强化技术采纳对不同受教育年限和不同种植面积农户生产绩效的提升作用存在差异。本研究为进一步推动中国作物营养强化项目实施提供政策参考。Whether farmers'adoption of biofortification crop technologies can improve production performance is an important practical issue for promoting the diffusion of biofortification crop technologies,improving population nutrition and health and developing high value-added agriculture.Taking biofortified wheat as an example,this article uses 606 household survey data from Henan,Hebei,Gansu and Shanxi provinces,taking into consideration the level of production,consumption and micronutrient defciencies.It explores whether and how farmers'adoption of biofortification crop technologies improve their production performance based on an endogenous switching model.The results are as follows.First,farmers'adoption of biofortification crop technologies can significantly improve their production performance.Specifically,after controlling farmers'self-selection bias,farmers'adoption of biofortification crop technologies has increased wheat yield per mu by 6.81% and wheat income per mu by 14.84%,respectively.Second,there is a certain regional heterogeneity in the impact of farmers'adoption of biofortification crop technologies on production performance.Third,the effect of farmers adoption of biofortification crop technologies on production performance is heterogeneous among farmers with different levels of education achievement and planting acreage.The conclusion provides policy reference for further promoting the implementation of biofortification projects in China.
