摘要
利用三阶段DEA模型,剔除外部环境因素和统计噪声的影响,测度农业生产废弃物循环利用绩效,并对各决策单元的技术效率进行分解,寻找循环利用效率较低的主因,并在此基础上探讨了区域绩效差异及原因。得出以下结论:①规模效率较低是导致资源性农业废弃物循环利用效率较低的主要原因。具体来看,农业废弃物基质化循环利用的综合效率均值仅为0.4089,还有59.11%的提升空间,纯技术效率均值高达0.9701,表现良好,规模效率均值仅为0.4215,成为农业废弃物循环利用效率较低的主因。②区域资源性农业废弃物循环利用绩效存在差异性,未剔除环境变量及统计噪声影响下,区域资源性农业废弃物循环利用绩效排序为:福建>山东>湖北>河南;剔除环境变量及统计噪声影响后,且优劣排序为河南>福建>山东>湖北,环境变量及经营环境与运气差异是重要原因。据此,提出了相应的对策建议。
Use three phase DEA model, the external environment factors and the effect of statistical noise were eliminated, agricultural production waste recycling behavior performance were measured, the technology efficiency of the decision unit was decomposed and the main reason for the low recycling efficiency, and discusses the regional differences and the reasons. The results show that： （1） More specifically , after eliminating the external environment factors and the effect of statistical noise, the average comprehensive efficiency of agricultural production waste recycling was just 0.4089, with room for 59.11% improvement, the average pure technical efficiency was as high as 0.9701, to perform well, scale efficiency 0.4215 only, which was the main reason for low efficiency of agricultural recycling behavior.（2） The regional agricultural＂ waste resource recycling performance exist differences , before eliminating the external environment factors and the effect of statistical noise, agricultural waste recycling performance order was Fujian 〉 Shandong 〉 Hubei 〉 Henan.After eliminating the external environment factors and the effect of statistical noise, agricultural waste recycling performance order was Henan 〉 Fujian 〉 Shandong 〉 Hubei, investigate its reason, environment variables and business environment and luck was the important reason . Accordingly, puts forward the corresponding countermeasures.
