摘　　要：基于土地经营规模对农户化肥投入影响的机理进行分析,结合贵州省赫章县古基镇海子村玉米种植户的调研数据,采用OLS计量方法探究土地经营规模对农户化肥投入的影响机理。结果表明:整体而言,土地经营规模对农户化肥投入具有显著的负向影响。具体来看,土地经营规模与农户化肥投入存在“U”型关系,即农户化肥投入水平随着土地经营规模扩大呈现出“先减后增”的变化趋势。其中,当土地经营规模为0.76 hm^(2)时,农户化肥投入量达到最低水平。此外,提高农户受教育程度、加入合作社、接受施肥相关技术培训以及降低土地细碎化程度和提高土壤质量等影响因素均有助于农户化肥的减量投入。据此,当地政府应当鼓励和引导农户适当扩大土地经营规模;充分发挥合作社作用,加强施肥相关技术培训;加大土地保护性投入力度,改善土壤质量,从而达到化肥减量投入的效果。Based on the mechanism analysis of the impact of land management scale on farmers’fertilizer input,combined with the survey data of corn farmers in Haizi village,Guji Town,Hezhang County,Guizhou Province,the influence mechanism of land management scale on farmers’fertilizer input was explored using OLS measurement method.The results showed that:overall,the scale of land management had significant negative effects on farmers’fertilizer input.Specifically,there was a U-shaped relationship between the scale of land management and the fertilizer input of farmers.The fertilizer input of farmers presented a trend of“first decreasing and then increasing”with the expansion of the land management scale.When the land management scale was 0.76 hm^(2),the fertilizer input of farmers were the lowest.In addition,improving farmers’education level,joining cooperatives,receiving technical training related to fertilization,reducing the degree of land fragmentation,and improving soil quality were factors contributed to the reduction of farmers’fertilizer input.Accordingly,the local government should encourage and guide farmers to appropriately expand the scale of land management;give full play to the role of cooperatives and strengthen fertilization related technical training;strengthen the input of land protection and improve soil quality,so as to achieve the effect of reducing the input of fertilizer.
