研究目的:横向比较评价我国31个省(市、自治区)农地利用结构的综合效率、技术效率和规模效率,并按照超效率对各地区进行排序。研究方法:数据包络分析(DEA)的C。R模型、BC。模型与超效率C2R模型。研究结果:(1)总体来说,大多数地区农用地利用结构综合效率低下,主要原因是技术效率太低;(2)我国74.2%的地区农地利用处于规模报酬递减阶段,要提高生产效率,必须调整用地结构;(3)超效率值较高的地区主要是经济发达地区和传统农业大省。
The purpose of this study is to evaluate total efficience, technical effieience and scale efficience of agricultural land use structure in 31 provinces, and arrange the regions in the order of superefficience. Methods of C2R Model, BC2 Model and SE-C2R Model of Data Envelopment Analysis (DEA)were employed. The results indicate that, (1)generally speaking, the total efficiency of agricultural land use structure in most areas is low because of their small technical efficience; (2)the returns of scale in 74.2% regions are decreasing, so we must adjust land structure in order to improve productive efficience; (3)the regions which have comparatively higher superefficience mainly are developed areas and traditional agricultural provinces.
