摘要
考虑到输入输出要素的有限取值范围,本文提出了DEA控制投影模型,并给出了在特定情形下非CRS有效单元有现实意义的投影。在工程应用中,本文采用所提出的模型,对182家创新型企业的技术创新能力与竞争力的调查数据进行了分析。研究结果表明,利用该控制投影模型得到的有效性分类不仅与传统CRS模型的有效性分类完全一致,而且其按行业分竞争力投影结果为企业审计竞争力提供了科学的高标,具有较强的工程应用价值。
Considering the restricted ranges of the input/output factors,we propose a multiobjective DEA projection model and also present the projection of CRS-inefficient DMUs.Then,survey data from 182 innovative enterprises'are used to analyze the relationship of competitiveness and technological innovation capability based on the model.We find that the efficiency distributions got from the model are evidently same with CRS model.Also,the projection results according to different industries,which are based on various competitiveness dimensions,provide the scientific benchmark for auditing competitiveness.
