基于改进超效率DEA的企业竞争情报分析
Analysis on Competitive Intelligence Work in Enterprises Based on a Modified Super-efficiency DEA Model
摘要
Abstract
Data Envelopment Analysis (DEA) is an effective approach for competitive intelligence work analysis to provide the visual and authoritative foundation for competition decision-making in enterprises. However, the basic DEA model is confined to a situation, in which multiple decision-making units appear relative effectiveness simultaneously, and it's hard to distinguish the difference degree of ef-fectiveness among them. Considering the premise, this paper aims to build up a modified Super-efficiency DEA model based on piecewise returns to scale, and argue the specific applications in analysis of competitive intelligence work, using 20 listed steel companies as a sam-ple. The research outcome indicated that, the modified Supper-efficiency DEA model can effectively distinguish the efficiency value of each decision unit.关键词
