径向集中式DEA模型的效率研究

A Study on the Efficiency of Radial Centralized Resource Allocation DEA Models

通过分析径向集中式BCC模型和径向集中式CCR模型的特征,发现集中式DEA模型中各决策单元的权向量是相同的.基于这一特征,提出了集中式DEA模型的技术与规模效率、技术效率、规模效率、SBM效率和MIX效率.

In this paper,characters of radial centralized resource allocation BCC model and radial cen-tralized resource allocation CCR model have been surveyed. In the centralized resource allocation DEA model, all decision units have the same weighs,based on which new concepts of centralized resource allocation DEA model were proposed： centralized radial technical and scale efficiency,centralized radial technical efficiency, centralized radial scale efficiency,centralized SBM efficiency and centralized MIX efficiency.
