| 摘 要： | 方向距离函数是对径向DEA模型的推广,它能够方便地处理存在非期望产出的情况,但其效率测量未解决单位不变性问题,这是制约方向距离函数在实践中应用的一个障碍。DEA数据标准化方法为效率测量方法提供了保持单位不变性的通用方法,同时采用标准化数据后,径向和非径向模型的效率测量结果保持不变。基于DEA数据标准化方法建立了具有单位不变性的方向距离函数效率测量方法。

| Abstract: | Directional distance function is the generalization of radial model in data envelopment analysis.It has the capacity of dealing with undesirable outputs,but the problem is that it has no unit-invariant measurement of efficiency,which hampers its application in empirical studies.Data normalization for data envelopment analysis is a universal solution to the problem of unit-invariance,and the efficiency keeps unchanged in radial and non-radial models after data normalization.A unit-invariant efficiency measur... |
