摘要
由于能够同时调整外部环境与随机误差等因素对效率计算的影响,由Fried et al.(2002)提出的三阶段DEA模型得到了广泛应用。但在对其中的管理无效率进行估计时,国内一些学者误用了Jondrow et al.(1982)的公式。本文给出了适用公式,并进一步给出了使用李双杰等(2007)提出的统一分布假设的三阶段DEA模型管理无效率的估计公式。
As a new technique for incorporating environmental effects and statistical noises,three-stage data envelopment analysis（DEA）model,which is proposed by Fred et al.（2002）,is widely used.While estimating managerial inefficiency,some domestic scholars misused the Jondrow et al.（1982）formula.In this paper,we provided the applicable formula,and further proposed the formula for estimating managerial inefficiency using the three-stage data envelopment analysis model with a general distribution assumption,which is proposed by Li Shuang-jie et al.（2007）.
