基于DEA模型的土地整理规划方案比选研究

研究目的:构建科学的评价模型,比较土地整理项目不同的规划方案,为规划方案的选择提供依据。研究方法:数据包络分析方法,层次分析法,实例验证法。研究结果:对重庆市偏岩镇土地整理项目3个不同规划方案采用带AHP约束锥的DEA方法计算出其效率值分别为:0.95871、0.96881、1,方案3为相对有效方案。研究结论:带AHP约束锥的DEA方法把传统DEA方法对输入输出数据的客观分析与决策者的主观偏好结合起来,应用于土地整理项目规划方案的比选,是一种可行的方法。

Study on the Comparison and Selection of Land Reconsolidation Planning Schemes Based on DEA Model

The purpose of the paper is to establish a scientific evaluation model for different planning schemes of land reconsolidation projects in order to provide reference points for the selection of schemes. Methods employed include data envelopment analysis, AHP and example verification. The results indicate:（1）efficiency values of three different planning schemes of land reconsolidation for Pianyan Town in Chongqing City are: 0.95871, 0.96881 and 1 respectively, which have been calculated via DEA method with AHP restraint cone;（2）scheme 3 is relatively effective. It is concluded that the DEA method with AHP restraint cone is a feasible approach for comparing and selecting land reconsolidation planning schemes due to its combination of objective analysis on data input and output from traditional DEA method and the subjective preference of decision maker.
