To modify the weakness of nonparametric approachs(e. g. DEA approach)which are only interested in whether dicision making unit (DMU)is on efficient production frontier,i.e.,it is a purely technical measure,we introduce the priees of inputs(outputs)into it and give the notions of cost,revenue,profit efficiencies and allocation efficiency.Thus,we consider the best comhnation of inputs(outputs) in order to judge whether DMU is cost minimization,rev-enue maximization or profit maximization. The relationship among all efficiencies is also dis-cussed.The method is illustrated by a data set。
