摘要
利用湖北省1710份农户的微观数据,运用Double-hurdle模型,实证分析土地细碎化对农户环境友好型技术采纳决策的影响。研究表明:(1)总体来说,土地细碎化对农户是否采纳环境友好型技术,以及采纳密度(采纳环境友好型技术的面积/总农地经营面积)均产生负向影响;(2)对男性和低自我效能感知主体而言,土地细碎化对其是否采纳环境友好型技术决策和采纳密度决策均产生负向影响;而对女性和高自我效能感知主体,则未产生显著影响;(3)土地细碎化对强社会网络主体的是否采纳决策产生影响,对其采纳密度决策不产生影响,土地细碎化对弱社会网络主体的是否采纳和采纳密度决策均产生负向影响;(4)土地细碎化对低农业收入依赖主体的采纳密度决策以及高农业收入依赖主体的是否采纳决策产生负向影响,对低农业收入依赖主体的是否采纳决策以及高农业收入依赖主体的采纳密度决策不产生影响;(5)土地细碎化对平原地区农户的是否采纳决策不产生影响,对其采纳密度决策产生影响,土地细碎化对非平原地区农户的是否采纳和采纳密度决策均产生负向影响。据此,建议着力推进高水平良田建设,激励农户环境友好型技术采纳决策的政策制定需要充分考虑农户异质性影响,实施精准施肥政策,并充分考虑不同自然环境特征(如地形等)的影响,针对平原和非平原地区的农户,采取差异化的激励策略。
Based on the microscopic data of 1710 farmers in Hubei province,this paper empirically analyzed the impact of land fragmentation on farmers′environment-friendly technology adoption decisions using Double-Hurdle model.The main research conclusions are as follows:(1)In general,land fragmentation has a negative impact on the decision that whether farmers adopt environment-friendly technology and density decision.(2)For men and farmers with low self-efficacy perception,land fragmentation has a negative impact on the adoption decision and density decision;However,there was no significant effect on women and farmers with high self-efficacy perception.(3)Land fragmentation has a negative impact on the adoption decision for farmers with strong social network,but has no impact on the density decision.Land fragmentation has a negative impact on the adoption decision and density decision for farmers with weak social network.(4)Land fragmentation has negative influence on the density decision for low agricultural income dependent farmers and the adoption decision for high agricultural income dependent farmers,but has no influence on the adoption decision for low agricultural income dependent farmers and the density decision for high agricultural income dependent farmers.(5)Land fragmentation has no influence on the adoption decision,but has an influence on the density decision for farmers living in plain areas.Land fragmentation has a negative influence on both the adoption decision and density decision for farmers living in non-plain areas.Therefore,this paper suggests that the policy of promoting the construction of high-quality farmland and encouraging farmers to adopt environmental-friendly technologies,which should fully consider the heterogeneous influence of farmers and implement precise policies,and also consider the effects of different natural environment characteristics(such as topography),adopting differentiated incentive strategies for farmers in plain and non-plain areas.
