企业间专利合作形成的多学科知识网络是提高创新绩效和实施多学科研发的重要网络平台。通过中国知识产权局公开的1985-2010年的36731条企业间专利合作数据,用社会网络分析方法分析了多学科知识网络的实际动态变化过程及其网络结构特点,以及网络中学科的分布特点。实证结果表明,这个多学科知识网络结构较完善,学科间的知识流动戢体即企业较多,对知识流动和创新将产生很好的促进作用;同时也希望本文的分析方法和分析结果为国家和企业的创新战略提供理论参考和实证资料。
Multidisciplinary knowledge network for enterprise-enterprise patent cooperation is an important network platform to improve innovation performance and to implement multidisciplinary and multisectoral cooperation. The actual dynamic variation and structure char- acteristics of the network and the distribution characteristics of disciplines in the network are analyzed through social network analysis based on data of 36,731 pieces of enterprise-enterprise cooperation patents during the period from 1985 to 2010 from the State Intellectual Prop- erty Office of the People' Republic of China. The multidisciplinary knowledge network as the result shows its structure is comparatively perfect and the carders for knowledge flow among subjects, the enterprises) are many, which has a positive influence on knowledge flow and innovation performance. At the same time, the method and the result of the analysis in this study are helpful for the innovation strategy of both the government and the enterprises as theoretical reference and empirical material.
