基于信息熵和DEA的企业技术创新能力评价方法

针对传统企业技术创新能力评价方法的局限性,提出一种基于DEA和熵值法的企业技术创新能力评价模型.该模型在熵值法给出的评价结果的基础上,结合DEA模型的计算结果,对传统评价结果进行合理的修正,使得修正后的结果具有考察不同投入规模单元之间产出绩效的比较分析功能.计算结果表明新的排名结果既反映了企业技术创新的绩效水平,又反映了投入产出率和产出的规模有效性,企业技术创新排名结果是合理的.

Evaluation Model Based on Information Entropy and DEA for Technological Innovation Capability of Enterprises

In view of the limitations on the conventional evaluation of the technological innovation capability of an enterprise, an evaluation model based on DEA and information entropy was developed for the capability. In the model the evaluation result given by entropy method was combined with the computational result by DEA model to modify the conventional evaluation results reasonably, thus making the modified results available to analyze the output performance from different sizes of input unit comparatively. Computational results showed that the ranking of enterprises, which are obtained from such an evaluation, reflects not only the technological innovation performance of those enterprises but also their input-output efficiency and the validity of their output scale. The ranking of enterprises' technology innovation capability is therefore proved reasonable.
