【摘要】：耕地细碎化是我国现代农业发展面临的突出问题,解决耕地细碎化问题是提高耕地利用效率的关键。基于农户耕地经营规模划分农户类型,利用武汉城市圈部分区县农户调查数据,采用DEA-Tobit模型分析了地块平均面积表征的耕地细碎化对耕地利用效率的影响。研究结果表明:1)小规模农户耕地经营面积平均为0.194 hm~2,利用效率为0.360;中规模农户耕地经营面积平均为0.492 hm~2,利用效率为0.446;大规模农户耕地经营面积平均为1.179 hm~2,利用效率为0.497;耕地利用效率与农户耕地经营规模呈正相关关系。2)耕地细碎化对农户耕地利用效率具有显著的影响,但对不同经营规模农户的影响存在显著差异;耕地细碎化对小规模农户的耕地利用效率具有正向作用,而对中、大规模农户的耕地利用效率具有负向作用;相对于小规模农户而言,细碎化对大规模农户的耕地利用效率的影响较大。因此,提高耕地利用效率,应鼓励耕地流转,为农户规模化经营耕地创造条件;在大力推进农业规模化经营的过程中,应将耕地整治与耕地流转有机结合起来,降低细碎化程度,以提高耕地利用效率。
[Abstract]:The fine fragmentation of cultivated land is a prominent problem in the development of modern agriculture in China, and the key to improve the utilization efficiency of cultivated land is to solve the problem of fine fragmentation of cultivated land. Based on the scale of farmland management of farmers and the survey data of some counties in Wuhan City Circle, DEA-Tobit model was used to analyze the effect of farmland fragmentation on the efficiency of cultivated land use. The results show that the average operating area of cultivated land for small farmers is 0.194 hmm2 and the utilization efficiency is 0.360; the average management area of cultivated land for middle scale farmers is 0.492 hmm2, and the utilization efficiency is 0.446; the average cultivated land area for large-scale peasant households is 1.179 hmm2, and the utilization efficiency is 2. The rate of cultivated land use efficiency is 0.497; the cultivated land use efficiency is positively correlated with the management scale of farm land. 2) the fine fragmentation of cultivated land has a significant effect on the farmland utilization efficiency of farmers. However, there are significant differences in the effects on farmers with different scale of management. The fineness of cultivated land has a positive effect on the utilization efficiency of small scale farmers, while it has a negative effect on the efficiency of cultivated land use of large scale farmers. Compared with small scale farmers, fineness has a great influence on the farmland utilization efficiency of large scale farmers. Therefore, in order to improve the efficiency of cultivated land use, cultivated land circulation should be encouraged to create conditions for farmers to manage cultivated land on a large scale, and in the process of vigorously promoting large-scale agricultural management, the improvement of cultivated land and the circulation of cultivated land should be organically combined. To reduce the degree of fineness in order to improve the utilization efficiency of cultivated land.
