基于SBM-DEA模型的河南省农业生产效率分析

Analysis of agricultural production efficiency in Henan province based on SBM-DEA model

在传统DEA模型的基础上,引入非期望产出指标建立SBM-DEA模型,对河南省18个地市的农业生产效率进行测算。研究结果表明:基于SBM-DEA模型,开封市、三门峡市和驻马店市的生产效率值为1。与不考虑非期望产出指标的生产效率相比,3个生产效率有效地市没有发生变化,但15个生产效率非有效地市的生产效率值均降低,平均降低值变动25.97%。生产效率非有效的原因主要集中在投入和非期望产出2方面。

Based on the traditional DEA model,this paper measures and calculates the production efficiency of 18 cities in Henan province with non-expected output index introduced and the SBM-DEA model established.The results show that,based on the SBM-DEA model,the production efficiency values of Kaifeng city,Sanmenxia city and Zhumadian city are 1.Compared with the production efficiency without considering the non-expected output index,the production efficiency of the three cities with effective production efficiency has not changed,but the production efficiency of the 15 cities with non-effective production efficiency all decreased,and the average reduction rate is 25.97%.The reason for the inefficiency of production efficiency is mainly concentrated on both input and non-expected output.
