The Application of the Evaluation Model of Innovation Ability of Zone Logistics System Basing on the Entropy DEA Model of Analysis of Main Factor of Grey Correlation (ID: 6-145)

摘要

The factors that influence on the improvement of the innovation ability in an area are extensive. In order to separate the facilitated function of the logistics from a lot of factors, this paper adopts the analysis method of grey-correlation main factor to screen out the evaluation target of the innovation ability of logistics, and establishes a non-uniform evaluation model of the innovation ability of zone logistics by introducing DEA (Data Envelopment Analysis) approach. For more than one DEA effective decision units, to analyse its validity further, this paper use entropy theory to establish a entropy DEA model and one example introduced. The research indicates that this method have obvious advantage and feasibility for the evaluation of zone logistics innovation ability, and in order to prove its practicability, this paper uses this model to evaluate the innovation ability of the logistics in northeast area, which doesn't only evaluate the discretion of innovation ability in different areas, but also can find the reason that causes the differences. Besides, this method debases the complex and corrrlation degree caused by multiple target evaluation, so that it reduces the error more effectively,and solves the problem of more than one effective decision units in DEA with simple index operation.
