基于DEA方法的土地利用效率提升

Dynamic Programming Analysis of Rational Land Use

在DEA(Data Envelopment Analysis)方法的基础上引入动态规划思想,对湖北荆州市8个县市区2015-2017年间的土地利用合理性进行了分析.实证分析结果显示:沙市区、荆州区的土地利用较为合理,监利县、松滋市、公安县、洪湖市、石首市、江陵县在土地投入、人员投入、资金投入、设备投入等方面都存在不同程度的冗余,导致了土地利用率不高.进一步的分析结果显示,这6个县市土地利用合理性都有较大的提升空间,分别为40.22%,23.71%,56.26%,58.58%,41.39%,63.32%.据此,给出了提升荆州市土地利用率的对策建议.

Based on the DEA method, the rationality of land use in 8 counties and cities of Jingzhou City from 2015 to 2017 was analyzed by introducing the idea of dynamic planning. The results of empirical analysis show that the land use in Shacheng and Jingzhou districts is more reasonable. There are redundancies in land investment, personnel investment, capital investment and equipment investment in Jianli, Songzi, Public Security, Honghu, Shishou and Jiangling counties, which leads to the low land use rate. Further analysis results show that the rationality of land use in these six counties and cities has a larger space to improve, which is 40.22%, 23.71%, 56.26%, 58.58%, 41.39% and 63.32% respectively. Accordingly, corresponding countermeasures and suggestions are given.
