摘要
运用社会网络分析法构建了基于3752个专利数据的协作研发网络,重点分析了区域层面的网络演化过程以及发明者层面的网络结构特征。研究结果表明,地区开放程度和经济发展水平是影响区域创新主体参与跨国协作研发活动的潜在因素;发达地区的内部和跨国协作研发活动频率及强度远高于与内陆区域之间的合作创新活动,反映出我国在R&D国际化进程中吸收的技术知识更多地聚集在发达地区,先进知识的跨区域流动机制有待进一步完善。
This paper analyses the evolution process and structure characteristics of the collaboration R&D network at regional and individual level. The network is constructed by adopting social network theory and is based on 3752 USPTO patents. The research outcome indicates that degrees of openness and eco- nomic development are two main factors that impact on the region's participation in the collaboration R&D network. Both the frequency and strength of intra-regional and international collaboration R&D activi- ties are higher than of interregional innovation cooperation in China, which implies that absorbed technical knowledge are more likely agglomerated in those developed regions during the R&D internationalization, and the interregional knowledge flow mechanism needs further improvement
