摘要/Abstract

摘要： 数据包络分析方法自提出以来,因其在评价决策单元相对有效性的诸多优势而得到了广泛应用,但其局限性之一在于要求决策单元具有相同的投入和产出性质。为了突破这一局限性,本文将参数方法引入DEA评价模型,以考虑外部环境因素对生产系统的影响;构建了一个新的三阶段半参数效率评价模型,其突出特点在于对"环境变量"和"非自由处置变量"的有效处理;选取国内某石油企业下属的各大油田作为分析对象,对上述三阶段模型进行了实证研究,证明了该三阶段模型的实用性和有效性。

Abstract: Since it is originally proposed, Data envelopment analysis (DEA) has been broadly applied because of its various advantages in evaluating the relative effectiveness of decision-making units. However, it has a significant limitation, i.e. the requirement of the same properties of inputs and outputs. In order to overcome this shortcoming, this paper applies parametric approaches to DEA so as to take the external environmental factors into account. It constructes a new three-stage semiparametric model, with the main feature of the effective processing of environmental variables and nondiscretionary ones. Then, it further applies the new model to the subsidiaries of a domestic oil corporation, and succeedes in testifying its practicability and effectiveness.

Key words: environmental variables, three-stage DEA, production efficiency of oil companies
