摘要: 利用熵权约束的DEA模型(E-DEA模型)对2016年江苏省13个地级市的农业投入、产出效率进行评价,为各决策单元确定了更加符合实际情况的相对效率,同时通过逆E-DEA模型对无效决策单元进行优化。结果表明,E-DEA模型能更有效地区分多有效决策单元;常州、南通、徐州、连云港、淮安、盐城、宿迁等7市的农业生产效率较低;造成农业生产效率较低的原因主要是农业机械投入冗余和过量使用化肥。

关键词: E-DEA模型, 逆E-DEA模型, 农业生产效率, 江苏省

Abstract: The DEA model with entropy weight constraint(E-DEA model) is used to evaluate the agricultural input and output efficiency of 13 prefecture-level cities in Jiangsu Province in 2016. The relative efficiency of each decision-making unit is determined to be more consistent with the actual situation. At the same time, the ineffective decision-making unit is optimized by the inverse E-DEA model. The results show that the E-DEA model can distinguish the multiple decision-making units more effectively; the agricultural production efficiency of the 7 cities including Changzhou, Nantong, Xuzhou, Lianyungang, Huaian, Yancheng and Suqian is lower; the main reasons for the low agricultural production efficiency are the redundant input of agricultural machinery and the excessive use of chemical fertilizer.

Key words: E-DEA model, inverse E-DEA model, agriculture production efficiency, Jiangsu province
