经营规模、地权稳定与农户有机肥施用行为——基于调节效应和中介效应模型的研究

Land Scale, Tenure Security and Adoption of Organic Fertilizer of Farmer: A Mediation and Moderated Model

以湖北和山东两省的农户调查数据为依据,实证分析经营规模对农户有机肥施用行为的影响,在此基础上,进一步研究了地权稳定性的调节作用以及经营规模影响有机肥施用行为的内在传导机制。研究发现:(1)经营规模对农户有机肥施用行为具有显著的正向促进作用;(2)地权稳定对经营规模影响农户有机肥施用的作用效果存在调节效应;(3)经营规模通过影响农户有机肥施用的行为态度和能力,正向激励农户有机肥施用;(4)有机肥施用行为能力的中介效应强于行为态度。本研究在一定程度上拓展了新古典经济学中有关经济偏好的理论解释,并对有效激励农户有机肥施用行为的对策措施提供了参考与建议。

Based on the investigation of farmers in Hubei and Shandong province, this paper explored the influential effect of land scale on farmer’s adoption of organic fertilizer, analyzed the moderating effect of tenure security, and discussed the mechanism through which land scale affect farmer’s adoption of organic fertilizer. Results showed that:(1)Land scale has positive effect on farmers’ organic fertilizer application.(2)Tenure security moderates the effect of land scale on farmers’ organic fertilizer application.(3)Cognition and ability of organic fertilizer application are mediating variables in the land scale-farmers’ organic fertilizer application relationship.(4)The mediating effect of ability of organic fertilizer application is larger than that of cognition of organic fertilizer application. This study enriches the theoretical interpretation of economic behavior in classical economics, and provides suggestions for motivating farmer’s adoption of organic fertilizer.
