基于全国农村固定观察点数据,以水稻、小麦和玉米主产区农户为研究对象,采用韧性评估模型、内生转换模型以及中介和调节效应模型,实证分析技术培训对农户粮食生产韧性的影响效应及其作用机制。结果表明:技术培训能显著增强农户粮食生产韧性,该结论在稳健性检验后依然成立;技术培训可以通过促进农户增加内部投资来提升粮食生产韧性,而不能通过促进农户增加外部投资来提升粮食生产韧性,土地经营规模则在技术培训对农户粮食生产韧性的影响中有正向调节作用;内部投资的中介效应和土地经营规模的调节效应在小麦和玉米种植户中更为明显。

[Abstract]
Based on the data of fixed observation points in rural areas, with the farmers in the main producing areas of rice, wheat and corn being taken as the research object, the impact of technical training on farmers’ grain production resilience and its mechanism were analyzed empirically by adopting the resilience assessment model, the endogenous switching model, and the mediating and moderating effect model. The research shows that technical training enhances farmers’ grain production resilience significantly, and the conclusion still stands after the robustness test. Technical training could enhance the grain production resilience through increasing farmers’ internal investment rather than external investment. The scale of land management has a positive moderating effect on the impact of technical training on farmers’ grain production resilience. Meanwhile, both the mediating effect of internal investment and the moderating effect of farmland scale are more significant in wheat and corn farmers than that in rice farmers.
