摘　　要：本文采用国家知识产权局专利数据库,基于2006-2015年发明专利合作申请数据,构建了我国发明专利合作网络,测度了发明专利合作网络的网络中心度、结构洞、集聚系数和小世界性等特征指标,分析了我国发明专利合作网络的演化趋势。研究结果表明:我国发明专利合作网络规模扩张迅速,网络合作关系日益增多,连通性越来越强,高等院校和大型国有企业在网络中占据核心位置,发明专利合作网络中的最强连接子网具备明显的小世界特征。Patents are the carrier of exclusive and novel technical knowledge and a visible result of innovative activities.This paper selects the application data of China’s invention patent cooperation from 2006 to 2015,constructs a patent cooperation network in China,analyzes the network indicators of the whole network and the network location of a single node by using social network research methods.And according to the stage characteristics of the patent cooperation network,this paper depicts the evolutionary trend of China’s patent cooperation network.The results show that:The scale of China’s patent cooperation network is large but the whole is scattered.Colleges and universities and large central enterprises occupy the core position in the network.The largest subgroup of the network has the characteristics of small world.From the perspective of evolutionary trend,China’s patent cooperation network has expanded rapidly,network relations have become increasingly close,the importance of nodes in the network has gradually increased,and the network as a whole has deviated toward the core nodes.
