我国农业高校专利合作网络演化研究

Evolution of the Patent Cooperation Network of Agricultural Universities in China

以我国36所农业高校为研究对象,以各高校1985-2014年在国家知识产权局申请的发明专利为基础,运用社会网络分析方法和专利分析法,分析各发展阶段合作网络结构演化的总体特征,及高校与高校合作子网、高校与科研机构合作子网、高校与企业合作子网所呈现的演化特征,明确专利合作网络演化路径,观察各高校与高校、科研院所、企业合作关系的变化。识别核心高校,并深度分析其在网络中特征的演化。结果表明网络演化呈现阶段化特征,各子网演化有自己的特点,核心农业高校合作特点也不尽相同。

Based on the patent data of 36 agricultural universities in China from 1985 to 2014, using social network analysis and patent a- nalysis, the general characteristics of network structure evolution and the evolution features of the sub-networks of university-university, u- niversity-research institute, and university-industry are analyzed, and the patent cooperation network evolution path and the core agricultur- al universities functioning actively in the networks are identified. Results show that the network evolution involves certain phases in gener- al; the evolution of each sub-network has its own characteristics, the cooperation among core agricultural universities has different charac- teristics.
