专利视角下虚拟现实技术合作创新网络研究
Research on the Collaborative Innovation Network of Virtual Reality Technology from the Perspective of Patent

本文利用虚拟现实领域的专利数据，探讨我国虚拟现实的发展现状以及合作创新网络的演进态势，以期为推动我国虚拟现实技术的繁荣发展提供有效建议。基于2003~2022年虚拟现实领域的专利数据，本文采取专利定量分析法和社会网络分析法，定量分析国内虚拟现实领域专利整体发展现状，并从网络整体结构和网络个体结构两个方面对合作创新情况进行分析。研究表明：我国虚拟现实领域专利创新得到了快速发展，合作创新网络整体规模不断增大，但网络密度较低，主体间协同程度较差；合作创新网络发展不均衡，各主体之间创新能力差距较大；企业在创新网络中占据首要地位，高校次之，科研机构等主体不具备明显中心性。
This article uses patent data in the field of virtual reality to explore the current development status of virtual reality in China and the evolution trend of collaborative innovation networks, in order to provide effective suggestions for promoting the prosperity and development of virtual reality technology in China. Based on patent data in the field of virtual reality from 2003 to 2022, this article adopts quantitative patent analysis and social network analysis methods to quantitatively analyze the overall development status of patents in the field of virtual reality in China, and analyzes the cooperative innovation situation from two aspects: the overall structure of the network and the individual structure of the network. Research shows that patent innovation in the field of virtual reality in China has developed rapidly, and the overall scale of collaborative innovation networks is constantly increasing. However, the network density is low, and the degree of collaboration between entities is poor; the development of collaborative innovation networks is uneven, and there is a significant gap in innovation capabilities among various entities; enterprises occupy the primary position in the innovation network, followed by universities, and scientific research institutions and other entities do not have obvious centrality.
