| 摘 要： | R&D效率评价是企业R&D管理中的一项重要内容,而评价方法的设计与选择是目前研究中的难点和核心。本文将DEA方法引入到对企业的R&D效率的评价中,以我国生物制药上市公司为研究对像,对样本公司R&D效率进行了全面的分析。研究表明,大多数生物制药上市公司的R&D效率差距不大,R&D效率与企业规模存在一定的联系,部分公司的R&D经费投入使用效率高于人员投入的使用效率。同时证明了DEA方法在企业R&D效率评价中的适用性。

| Abstract: | Efficiency evaluation of R&D is a very important part of R&D management in enterprises,but the design and choice of evaluation method is the most difficult.This paper uses DEA method to analyze R&D efficiency of the specimen,based on the listed companies of biochemical and pharmaceutical.The results indicate that the span of R&D efficiency of most listed biochemical and pharmaceutical companies is very little,the R&D efficiency has relationship with the companies size to some extent,the R&D expense of some companies is more efficient than the R&D staff expense.Meanwhile it is improved that the DEA method is suitable for the R&D efficiency evaluation. |
