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。

英文摘要：

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 or 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.
