摘要
本文基于河南、宁夏两省873份微观农户调研数据,利用DEA和Tobit模型,从测算农户小麦生产效率入手,分析了耕地流转对小麦生产效率的影响,并探讨了农户生计分化在耕地流转对小麦生产效率的影响过程中的调节作用,以期在现阶段农户不断分化的现实背景下,为完善耕地流转相关政策提供理论参考。研究结果显示:①耕地转入通过土地规模效应正向影响小麦生产规模效率,进而提升小麦生产综合效率;耕地转出通过要素溢出正向影响小麦生产技术效率,进而提升小麦生产综合效率。②农户生计分化在耕地流转对小麦生产效率的影响过程中具有调节作用:在农户生计分化的调节作用下,耕地转入对小麦生产综合效率的正向影响减弱,耕地转出对小麦生产综合效率的正向影响增强。③耕地转入面积对小麦生产综合效率和规模效率均呈现"倒U型"影响,在流转规模分别到达46.277亩和37.125亩之后,耕地转入面积对小麦生产综合效率和规模效率的影响由正转为负;耕地转出面积对小麦生产综合效率表现为直接的正向影响。最后,提出了完善耕地流转市场,加强农户非农技能培训,以及大力开展农技推广工作等建议。
This study used data envelopment analysis(DEA)and Tobit model to measure farming household food production efficiency,analyze the impact of farmland transfer on grain production efficiency,and discuss the moderating effect of household livelihood differentiation on the impact of farmland transfer on grain production efficiency based on the microscopic farming household survey data.The results show that the level of wheat production efficiency in the research area was relatively high.Cultivated land inflow positively affects wheat production scale efficiency through land scale effect,thus promoting the improvement of comprehensive efficiency.Cultivated land outflow positively affects the technical efficiency of wheat production through factor spillover,thus promoting the improvement of comprehensive efficiency.Under the moderating effect of farmers’livelihood differentiation,the positive influence of cultivated land transfer on the comprehensive efficiency of wheat production was weakened,while the positive influence of cultivated land outflow on the comprehensive efficiency of wheat production was strengthened.Cultivated land inflow area has an inverted U-shaped effect on the comprehensive efficiency and scale efficiency of wheat production.When the transfer scale reaches 46.27 mu and 37.13 mu respectively,the impact of cultivated land inflow area on the comprehensive efficiency and scale efficiency of wheat production changes from positive to negative.Cultivated land outflow area has a direct positive effect on the comprehensive efficiency of wheat production.In conclusion,we should pay close attention to improving the farmland circulation market,encourage part-time farmers who rely less on farming to transfer their farmland management right to other households,and vigorously promote the dissemination of agricultural technologies.
