本文利用我国11个粮食主产省不同经营规模农户的微观调研数据,基于二元选择Probit模型,探析了不同经营规模农户持续使用测土配方肥行为差异及其影响因素的共同点和不同点.研究得出结论:不同规模组农户中,持续使用测土配方肥的样本比例分布存在明显差异,大规模组农户使用比例最高,小规模组农户比例最低;从外在因素看,粮食实现增产、测土服务、施肥信息渠道、施肥技术培训对三组农户测土配方肥使用行为具有显著正效应,其中测土服务的影响程度最大;市场化程度和规模化程度高的农户倾向于持续使用测土配方肥.在实证研究的基础上,本文提出了相应的政策建议.%This paper researches the behavior of using soil testing formula fertilizer at farms of different sizes. The study develops a probit model based on peasant household survey data from 11 grain production areas. The results prove that: First, obvious differences exist in the distribution of formula fertilizer use ratio among farms of different sizes; large-scale farmers are the highest, small-scale farmers are the lowest. Second, from external factors, the increased yield of corn, soil testing services, and information dissemination, it is clear that training has a significant positive effect on farmers' use behavior; the influence of soil testing services is the greatest. Third the higher the degree of organization, marketization and scale of a farm, the more likely the farmer is to use soil testing formula fertilizer. Policy recommendations are made on the basis of the empirical research presented in this paper.
