| 摘 要： | 以220件混合动力汽车高被引专利为研究对象,运用社会网络分析方法,从点度中心度、中间中心度、核心-边缘结构和凝聚子群等角度对构建的网络进行分析。结果表明:美国和日本的一些企业在该领域的研发实力较强;企业网络中的小团体现象较严重,只有丰田等少数企业拥有较大竞争优势;各大企业的技术竞争点集中在动力系统、控制系统和蓄电池等方面。

| Abstract: | Taking 220 highly cited patents of hybrid electric vehicle as the research objects and social network analysis as the research method,this paper makes a detailed analysis on the established network from the perspective of point centrality,between centrality,core-periphery structure and cohesive subgroups. The results show that some American and Japanese enterprises have stronger capability of research and development; the appearance of small group in firm network seems in a serious situation,and Toyota has stronger competitive advantage; the primary study of research and development in HEV area focus on the drive system,control system and battery and so on. |
