标题：Evaluation on Input-output Efficiency of Land Consolidation Project Based on DEA --- A Case Study of Land Consolidation Project in Chongyang County, Hubei Province
摘要：This article studies four land consolidation projects in four towns of Chongyang County, Hubei Province, establishes system indexes for evaluation on input and output of land consolidation projects in all the four towns and employs DEA method to make an analysis of the relative efficiency of the projects in order to make an analysis of the actual efficiency of land consolidation, decide whether land consolidation is highly effective and point out a direction of improvement for higher land consolidation efficiency in the future. The result shows that the land consolidation in Qingshan Town and Lukou Town is ineffective and the land consolidation in Shaping Town and Baini Town is effective, with an average efficiency of 0.77. It proves that the overall efficiency of land consolidation in the four towns is at an upper-and-middle stream. Inefficiency is mainly manifested in cost of construction of a project, original equipment cost, other costs and redundancy of unpredictable costs, while increment of land use ratio, quantity of employment added per unit investment, rate of coverage of newly added green vegetation, newly added annual pure economic interests and yield rate of static investment have too low output. In order to enhance the efficiency of land consolidation, it is necessary to arrange all sorts of input in a reasonable way and pay enough attention to the output.
