摘要
基于全国14个省份2022年的微观调查数据,在理论分析的基础上,主要运用逆概率加权和逆概率加权回归调整的方法,实证检验了农业生产托管对粮食生产技术效率的影响效果和作用机制。研究发现:(1)农业生产托管参与决策受多种因素影响,是农户的一种“自选择”行为。(2)农户购买农业生产托管服务有利于提高粮食生产技术效率,相较于未购买服务的农户,购买服务农户的粮食生产技术效率会高出约2.51%~3.40%。原因在于,农业生产托管能够有效减少粮食生产中的农药、化肥投入,提高种粮农户的技术采纳概率。(3)农业生产托管对粮食生产技术效率的提升作用在产销平衡区、在小麦生产中表现得最为明显,且这一正向作用在小规模、高兼业水平、新生代的农户群体中更为突出。
Based on micro survey data from 14 provincial-level regions of China in 2022,this paper empirically tests the impact and mechanism of agricultural production trusteeship on technology efficiency of grain production by using inverse probability weights and inverse probability weighted regression adjustment methods.The result shows that:(1)The participation of agricultural production trusteeship in decision-making is influenced by multiple factors and is a self-selection behavior of farmers.(2)The purchase of agricultural production trusteeship services by farmers is beneficial for improving the technical efficiency of grain production.Compared to farmers who do not purchase services,the technical efficiency of grain production by farmers who purchase services is about 2.51%-3.40% higher.The reason is that agricultural production trusteeship can effectively reduce the input of pesticides and fertilizers in grain production,and increase the probability of technology adoption by grain farmers.(3)Further analysis shows that the improvement effect of agricultural production trusteeship on the technical efficiency of grain production is most evident in the balancing areas of grain production and marketing and in wheat production,and the positive effect is more prominent in small-scale,high level of part-time employment,and the new generation of farmers.
