摘要
运用超效率DEA模型对2013年中原经济区30个省辖市的农业生产效率进行测算,并对其空间分异特征和冗余度进行分析.结果表明:1)中原经济区东部及东南部地区的农业生产效率高于其它城市,区域差异明显,且处于农业生产效率高水平阶段的城市在空间上呈连续分布状态;2)区域经济发展水平与农业生产效率并非呈正相关关系;3)从投入-产出关系来看,农业生产效率非有效城市在资金和土地方面投入过剩现象明显,而对于农业机械化方面的投入明显不足,资金利用效率、农业用地集约化程度和农业机械化水平较低.
In this paper,super-efficiency DEA model and the method of spatial autocor-relation were used to analysis the agricultural production efficiency and spatial heterogeneity characteristics of 30 cities in Central Plains Economic Region in 2013.The results demonstrated：1）The level of agricultural production efficiency in the east and southeast of Central Plains Economic Region was higher than other cities.The regional differences were significant and cities of high efficiency levels distributed continuously in space;2）The level of economic development and agricultural production efficiency was not a positively correlated;3）In the view of input-output,the non-effective cities exhibited excess investment in funds and land,while insufficient in that of farming mechanization;Besides,the capital utilization efficiency,the intensity of agricultural land use and the agricultural mechanization level are still relatively low.
