摘要：耕地流转和土地确权是实现小农户与现代农业有效衔接的重要途径。本研究基于河南省612份农户调研数据,运用随机前沿生产函数对小麦种植技术效率进行测算,采用Tobit模型实证探究耕地流转、土地调整及二者的交互项等因素对技术效率的影响,并用工具变量法解决了耕地流转的内生性问题。结果表明:样本农户小麦技术效率为0.810,还有较大的提升潜力;且小麦技术效率异质性特征明显,不同农户之间差异较大。流转户的小麦技术效率高于未流转户。无论对于流转户还是未流转户,其土地未调整户的小麦技术效率都高于土地调整户。通过耕地流转和土地调整的联合检验发现,耕地流转对样本农户小麦技术效率有正向调节作用,土地调整对小麦技术效率有反向调节作用,耕地流转能够在一定程度上抑制土地调整给小麦技术效率带来的损失。户主年龄、担任村干部、参加农业培训、离井距离、受灾等对小麦技术效率有显著影响。由此可见,一方面应推动耕地流转,加快农地规模化和现代化经营进程;另一方面应巩固土地确权成效,加强农业技能培训和农田水利基础设施建设。
Farmland transfer and its use right confirmation are crucial for small-scale farmers’access to modern agriculture.Based on a survey data of 612 rural households in Henan Province,this paper adopts the stochastic frontier production function to calculate the technical efficiency of wheat production and the Tobit model to examine the effect on technical efficiency exerted by farmland transfer and reallocation and their interactions.In addition,this paper also attempts to solve the endogenous problems of farmland transfer by adopting the method of instrumental variable.Results show that the average technical efficiency of the sample is 0.810 and there is still a greater potential for improvement.The heterogeneity of the technical efficiency of wheat production is obvious and there are great differences among different farmers.The technical efficiency of wheat production of those households with farmland transfers is higher than that of the households without farmland transfers.Whether with or without farmland transfer,the technical efficiency of wheat production of those households without land reallocation is higher than that of the households with land reallocation.Through the joint inspection of farmland transfer and land reallocation,this paper finds that farmland transfer has a positive regulating effect on the technical efficiency,whereas farmland reallocation exerts a negative effect on the technical efficiency.Farmland transfer,to a certain extent,can cut the losses of the technical efficiency caused by farmland transfer.The age of household head,the role of a village leader,agricultural technical training,the distance from irrigation water,and agricultural disasters have obvious effects on the technical efficiency.Accordingly this paper suggests to accelerate the transfer of farmland,to speed up the process of scale production and modernization of farmland,to consolidate the result of farmland use right confirmation,and to enhance agricultural skill training and the construction of farmland water conservation projects。
