新兴技术知识网络跨界融合的机理与实证研究

The mechanism of cross-border integration of emerging technology knowledge network and its empirical research

新兴技术跨界创新推动了知识网络的跨界融合演变。基于德温特专利数据库,以虚拟现实技术为研究对象,运用社会网络分析法,通过构建专利引文网络,研究新兴技术知识网络跨界融合的知识流动路径演化和网络态势。结果表明:新兴技术知识流动路径按照"单向路径-混向路径-双向路径"模式演化,核心企业和外围企业的不断增加拓宽了双向路径的发展空间;知识流动路径数量的激增和方向的分散导致企业和地区知识网络跨界融合的涌现,呈现出异质性知识增加、知识连接灵活、网络规模扩大的跨界融合特征;中心企业与中心地区通过"中心地区自引、非中心地区引中心地区"的知识流动偏好进一步强化跨界融合能力,体现出明显的先发优势。

The cross-border innovation of emerging technologies has promoted the trend of the cross-border integration in the internal knowledge network.This paper analyzes the evolution of the knowledge flow path and the structural characteristics of an emerging technology knowledge network with the development of cross-border integration based on the patent data coming from DII(Derwent Innovation Index),which targets the field of virtual reality technology and uses social network analysis method as well as patent citation network.The results show that the emerging technology knowledge flow path evolves from one-way path to mixed path to two-way path,and the continuous increase of both core and peripheral enterprises widens the development space of the two-way path.The number of knowledge fiow path has increased sharply and the direction of that has dispersed,which leads to the emergence of the cross-border integration of knowledge networks between enterprises and regions.And the cross-border integration is characterized by increased heterogeneous knowledge,flexible knowledge connection and expanded network scale.The central enterprises and central regions further strengthen the cross-border integration capacity through the knowledge flow preference of"Central regions cite the domestic knowledge and non central regions cite the knowledge in central regions",reflecting obvious first mover advantages.
