邻里效应能否促使稻农施用生物农药?——基于鄂、赣、浙三省农户调查数据的考察

在构建邻里效应对农户生物农药施用行为影响的理论模型基础上,利用鄂、赣、浙三省农户的调研数据,实证检验了邻里效应对农户生物农药施用行为的影响,在此基础上,进一步讨论了邻里效应促使稻农施用生物农药的条件与内在作用机制。结果表明：第一,55.76%的样本农户施用过生物农药,且施用生物农药的农户有较强的邻里关系。第二,邻里效应对农户生物农药施用行为有显著的正向影响,且强邻里效应的农户生物农药平均施用量要显著高于弱邻里效应农户。第三,邻里效应对稻农生物农药施用行为的影响存在条件限制,对高收入农户和规模户而言,邻里效应的影响不显著。第四,邻里效应对农户生物农药施用行为有显著直接作用,也通过降低信息搜寻成本和有效规避农业生产风险两条路径间接影响农户生物农药施用行为。

Can the neighborhood effect encourage rice farmers to apply biological pesticides: Evidence from survey data of farmers in Hubei,Jiangxi and Zhejiang provinces

Based on the establishment of a theoretical model of the influence of neighborhood effect on farmers' biopesticide application behavior, this paper uses survey data of farmers in Hubei, Jiangxi and Zhejiang provinces to empirically test the impact of neighborhood effect on farmers' biopesticide application behavior. On this basis, the conditions and internal mechanism of neighbourhood effects for rice farmers to apply biological pesticides were further discussed. The results show that: first, 55.76% of the sample farmers have applied biological pesticides. The farmers who applied biological pesticides have a strong neighborhood relationship. Second, the neighborhood effect has a significant positive impact on farmers' biological pesticide application behavior. The average application amount of biological pesticides by farmers with strong neighborhood effects is significantly higher than that of farmers with weak neighborhood effects. Third, there are conditional restrictions on the influence of neighborhood effect on rice farmers' biological pesticide application behavior. For high-income farmers and large-scale households, the neighborhood effect is not significant. Fourth, the neighborhood effect has a significant direct effect on farmers' biological pesticide application behavior, and it also indirectly affects farmers' biological pesticide application behavior through two paths of reducing information search costs and effectively avoiding agricultural production risks.
