| 摘 要： | 以2006-2008年的51家制造业上市公司为样本,运用DEA-Tobit模型,分别检验了研发投入和专利产出对企业技术效率的影响。实证结果表明:R&D经费投入对技术效率具有显著的积极影响;研发人员投入对技术效率的当期效应和长期效应均为正相关,但只在累积效应模型中通过了显著性检验;发明专利对样本企业的技术效率具有显著的积极影响,并具有明显的滞后性;实用新型专利对样本企业的技术效率具有显著的负效应,同时存在明显的滞后性;外观设计专利对样本企业的技术效率具有负效应,但不显著。结果启示,可以通过制定合理的研发战略来提升企业的自主创新能力,这是企业提高技术效率的重要途径之一。

| Abstract: | Based on the sample of 51 manufacturing listed companies which disclose the data of firms'innovation activity during 2006 to 2008,this paper tests the effects of R&D investment and patents on technical efficiency by using DEA Tobit model after controlling the related factors. The empirical results show that R&D impact significantly and positively the technical efficiency, and the R&D manpower input is positive with technical efficiency in the short and long run effects but the coefficients pass through the ... |
