    摘要:

    利用山东、河南、陕西、四川四个农业大省942户的调查数据,通过因子分析法从关系嵌入、结构嵌入两个维度对农户社会网络嵌入程度进行测度,运用Probit模型,实证分析农业劳动力老龄化、社会网络嵌入对农户农技推广服务获取的影响。研究结果表明:农业劳动力老龄化对农户农技推广服务获取呈显著的负向影响,社会网络嵌入能够缓解农业劳动力老龄化对农户农技推广服务获取的不利影响。从不同维度的社会网络嵌入看,关系嵌入与结构嵌入均对农户农技推广服务获取有显著的正向影响,但仅结构嵌入显著缓解农业劳动力老龄化对农技推广服务获取的负面冲击,关系嵌入作用并不显著。进一步检验表明,社会网络嵌入的缓解效应随着老龄化程度的提高而增强。基于此,提出缓解农业劳动力老龄化对农户农技推广服务获取负面影响的可行路径。

    Abstract:

    This paper uses the micro-data of 942 households in four major agricultural provinces of Shandong,Henan,Shaanxi and Sichuan to measure the degree of social network embedding of farmers from the two dimensions of relationship embedding and structure embedding.Probit model is employed to make an empirical analysis of the impact of the aging of agricultural labor and social network embedding on farmers’ access to agricultural technology extension services.The results showed that the aging of agricultural labor force has a significant negative impact on the acquisition of agricultural technology extension services for farmers.The social network embedding can alleviate the adverse effects of agricultural labor aging on farmers’ access to agricultural technology extension services.From the perspective of social network embedding in different dimensions,both relationship embedding and structure embedding have a positive impact on farmers’ access to agricultural technology extension services,but only structural embedding significantly mitigates the negative impact of agricultural labor aging on the acquisition of agricultural technology extension services while the relationship embedding effect is not significant.Further tests showed that the mitigation effect of social network embedding will increase with the aging degree.Therefore,this paper proposes a feasible path to alleviate the negative impact of agricultural labor aging on farmers’ agricultural technology extension services.
