基于DEA的土地整理项目投入产出效率评价——以山东省若干国家投资土地整理项目为例

为了对土地整理项目的投入产出效率作出定量评价，并为推进土地整理项目的科学实施提供参考。对土地整理项目的投入产出要素进行分析计算，然后采用DEA方法对项目相对效率作出评价。结果表明：各项目相对效率值有9个为1，只有河口区为0.81。说明山东省土地整理项目总体而言具有较好的综合效益和合理的投入产出，但是河口区的土地整理项目投入结构相对不合理，表现为土地平整、农田水利、田间道路、生态防护四项投入存在冗余，且社会效益未达最大化。为促使土地整理项目取得良好效益，应在实施过程中制定科学的规划方案，合理安排各项投入，并重视对项目社会效益的投入。

Evaluation on Input-Output Efficiency of Land Consolidation Projects Based on DEA -A Case Study of Several National Invested Land Consolidation Projects in Shandong Province

The purpose of this paper is to make quantitative evaluation on input-output efficiency of land consolidation projects and to provide reference for the scientific implementation of land consolidation projects. Method employed is DEA.. The relative efficiency value of Heikou District is 0.81, the other 9 projects is 1. It showed that most projects studied achieve a better economic, social and ecological benefits and rational input-output. But the investment structure of land consolidation project in Heikou District is relatively irrational, the project has redundant inputs in land leveling, irrigation, field road, and ecological protection. The social benefits were not maximum either. In order to achieve better benefits, scientific planning should be made and arrange inputs reasonably. The inputs for social benefits also should be emphasized.
