DEA方法在农村信息网络资源评价中的应用——以邮政网络为例

Application of DEA Method in Evaluation of Rural Information Network Resources—Take Postal Network as an Example

摘要: 本文针对现有资源效率评价中存在的输入输出数据的异质性问题，提出了一种基于灰色聚类的改进DEA效率评价模型；以邮政网络为例，根据网络资源配置的原则，把县域组织作为邮政网络运行主体，通过对邮政网络资源特性的分析，建立了邮政网络资源配置评价指标体系；利用该模型对所选地区18个县域邮政组织的实物网络和邮政综合网络资源配置效率分别进行了评价分析。结果表明：(1) 该方法实现了异质决策单元的同质化，有效降低了县域邮政组织在网络资源配置中的管理运行成本。(2) 该模型不但对简单网络资源配置效率评价有效，对于复杂网络同样有效。同时该方法为相关资源配置效率的评价问题提供了新的思路。

Abstract: Aiming at the heterogeneity of input and output data in the existing resource efficiency evaluation, an improved DEA efficiency evaluation model based on Grey clustering is proposed. Taking postal network as an example, according to the principle of network resource allocation, county organi-zations are regarded as the main body of postal network operation. Through the analysis of the characteristics of postal network resources, the evaluation index system of postal network resource allocation is established. The model is used to evaluate and analyze the resource allocation efficiency of physical network and comprehensive network of postal organizations in 18 counties in the selected area. And the results show that: (1) The method can realize the homogeneity of heterogeneous decision making units, and effectively reduce the management and operation cost of county postal organization in network resource allocation. (2) The model is effective not only for evaluating the resource allocation efficiency of simple networks, but also for complex networks. At the same time, this method provides a new way to evaluate the efficiency of resource allocation.
