Abstract:

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.
