最近看到论坛上总有人在力捧那些发了国外牛刊的人(例如最近说华科某人发了JOE),似乎沉默就是失败。但你们可曾知道,人大经济学院教授魏权龄在SCI、SSCI上发了一堆论文?人家1997年就发了Journal of Econometrics!可惜,经济学院从未宣传,以至于居然有人说人大经济学院号称全国第一却从未在世界前200名经济学杂志上发表论文。真是可笑。

Abstract
We study the properties of the K-cone in a generalized Data Envelopment Analysis (DEA) model. This model includes the following four important classes of models: Charnes et al. (1978) model, Banker et al. (1984) and Charnes et al. (1985) model, Färe and Grosskopf (1985) model, and Seiford and Thrall (1990) model as its special cases. The main contribution of this paper is to introduce to the above four models (a) the input-output preference cone W to represent the relative importance of different input/output categories viewed by the evaluator (one who evaluates the decision-making units (DMUs)); and (b) the so-called predilection cone to describe preference of the evaluator to selected DMUs. We discuss the new characterizations of DEA efficient DMUs in the case of K-cone. We also describe the use of elementary predilection operators to achieve special preference for one or more DMUs. This method can be easily applied to find all the DEA efficient DMUs that are on a common efficient face as one or more prespecified DMUs. The method provided in this paper is complete in the sense that only those DMUs that are on a common efficient face with the predileccted ones will be DEA efficient after predilection. We believe that the results of this paper will play in important role in determining the structure of efficient frontiers.

下面这段话是网上找的,魏老师真厉害:

1978年由著名的运筹学家A.Charnes,W.W.Cooper和 E.Rhodes首先提出了一个被称为数据包络分析(Data Envelopment Analysis,简称DEA)的方法,去评价部门间的相对有效性(因此被称为DEA有效).他们的第一个模型被命名为CCR模型.从生产函数角度看,这一模型是用来研究具有多个输入、特别是具有多个输出的“生产部门”同时为“规模有效”与“技术有效”的十分理想且卓有成效的方法.1984年 R.D.Banker,A.Charnes和W.W.Cooper给出了一个被称为BCC的模型.1985年Charnes,Cooper和 B.Golany, L.Seiford, J.Stutz给出了另一个模型(称为CCGSS模型),这两个模型是用来研究生产部门的间的“技术有效”性的.1986年Charnes,Cooper 和魏权龄为了进一步地估计“有效生产前沿面”,利用Charnes, Cooper和K.Kortanek于1962年首先提出的半无限规划理论,研究了具有无穷多个决策单元的情况,给出了一个新的数据包络模型——CCW模型.1987年Charnes, Cooper,魏权龄和黄志民又得到了称为锥比率的数据包络模型——CCWH模型.这一模型可以用来处理具有过多的输入及输出的情况,而且锥的选取可以体现决策者的“偏好”.灵活的应用这一模型,可以将CCR模型中确定出的DEA有效决策单元进行分类或排队等等.这些模型以及新的模型正在被不断地进行完善和进一步发展
