Empirical Studies of Agricultural Waste Resource Recycling Efficiency and Regional Difference
使用三阶段DEA模型，剔除外部环境和统计噪声后，测算中国农业废弃物资源化利用效率，发现规模效率低下是主因，并揭示区域差异及环境因素影响。
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.
