摘　　要：土地整理是中国实现耕地总量动态平衡和确保耕地红线的重要措施和手段,在明确投入产出因子的基础上,依据土地整理多投入多产出的特点,利用数据包络分析(DEA)方法对中部土地整理区各省份在土地整理项目上的投入产出效率进行计算,对相应效率损失进行分析,结果表明:(1)中部土地整理区土地整理投入产出效率在总体上具有规律性,其中农业生产条件较好的省份,不论投入产出效率值是否达到最优,皆为规模收益递减;农业生产条件较差的省份则相反;(2)由于地貌、土壤、气候等农业生产和生态条件不同,各省份投入产出效率差异较大;(3)由于规模效益差异使得各省份土地整理项目产出不随投入规模的增加而增大,土地整理投入产出结构存在不合理。Land consolidation plays a key role ensuring the target of farmland protection. in keeping the dynamic equilibrium of arable land and It is of great significance to guarantee food security, relieve contradiction between human and environment, as well as promote the urbanization process and socio-economic development. However, as Chings land consolidation history was ver- y short, the undertaken land consolidation projects were mainly focused on the increase of culti- vated area, while social and ecological benefits were ignored to a certain extent. Comprehensive e- valuation lack of regional input-output efficiency was usually employed as a method for benefit as- sessment. In this paper, based on determining the input and output factors, in accordance with characteristics of multi-input and multi-output, DEA method was applied to calculate the input- output efficiency and to analyze the corresponding efficiency loss by taking central land consolida- tion region as DMU. The results are obtained as follows. 1） In general, land consolidation bears regularity and difference. All the provinces with advantageous agricultural production conditions have decreasing benefits to scale, regardless of the optimal value of input-output efficiency, whereas the situation in provinces with disadvantageous agricultural production is on the contra ry. 2） Due to the differences of topography, soil, climate, and other agricultural production and ecological conditions, the efficiency between various provinces are quite different. Both input and output factors need to be modified in non-DEA efficient DMU, and there is significant difference in the extent of adjustment as well. 3） Due to scale differences and irrationality of input-output structure, the land consolidation output does not increase with the input. In addition to the prov inces at low level of relative efficiency, such as Shanxi, Hubei and Anhui, the tendency is also observed in relatively efficient provinces
