基于专利分析的新能源汽车技术创新合作网络研究

Research on Innovation Cooperation Network of New Energy Vehicle Technology Based on Patent Analysis

以中国国家知识产权局数据库中2002—2017年发表于新能源汽车领域的合作申请专利为原始数据,构建新能源汽车技术创新合作网络。运用社会网络分析法,从整体网结构特征及自我网络的空间特征等方面进行分析。研究结果表明:新能源汽车合作创新具有主体多元性、合作阶段性、网络扩张性以及创新主体空间分布不平衡等特点,新能源汽车技术创新主体之间需要加强协同合作,促进产业集群化发展。

Based on the original data of the cooperative application patents published in the database of China’s State Intellectual Property Office in the field of new energy vehicles from 2002 to 2017,a new innovation cooperation network of energy vehicle technology is constructed.The social network analysis method is used to analyze the characteristics of the overall network structure and the spatial characteristics of the network.The research results show that the new energy vehicle cooperation innovation has the characteristics of diversified main bodies,phased cooperation status,expanding network and unbalanced spatial distribution of innovation subjects.New energy vehicle technology innovation subjects need to strengthen their synergy and promote industrial cluster development.
