融合社会资本与知识存量的合作创新网络演化机制研究

Revealing the Role of Social Capital and Knowledge Stock in Driving the Evolution of CollaborativeInnovation Networks

[目的/意义]基于创新主体的社会资本与知识存量,深入研究合作创新网络的动态演化特征与内在机制,助推创新主体整合优势资源、拓宽合作渠道、进一步提升创新能力。[方法/过程]综合运用知识要素抽取技术、社会网络分析方法及网络动态演化模型,在构建领域合作创新网络与整体知识网络的基础上,引入单个创新主体的个体知识网络,深入分析社会资本与知识存量对合作创新网络演化的驱动机制。[结果/结论]以2003年—2022年光刻领域专利数据为基础开展实证分析,发现合作创新网络的传递性、创新主体间的组织邻近性与认知邻近性以及创新主体自身的知识多样性、知识组合潜力驱动了创新网络中合作关系的建立;创新主体的度中心性、个体知识网络的传递性对合作创新网络的形成具有负向作用。最后,面向进一步推动技术领域合作创新提出建议。

[Purpose/Significance]Based on social capital and knowledge stock of innovation entities,the in-depth research on the dynamic evolution characteristics and internal mechanisms of collaborative innovation networks can promote the innovation entities to integrate superior resources,expand collaboration channels,and further enhance their capacity for innovation.[Method/Process]With knowledge elements extraction,network dynamic modeling and social network analysis,this paper constructed domain’s collaborative innovation network and overall knowledge network,and focused on the local knowledge networks of individual innovation entities to reveal the driving mechanism of social capital and knowledge stock on the evolution of collaborative innovation networks.[Result/Conclusion]On the empirical analysis of the lithography patent data from 2003 to 2022,this paper exposes that the transitivity of collaborative innovation networks,the organizational proximity and cognitive proximity between innovation entities,as well as the knowledge diversity and knowledge combination potential of innovation entities drive the establishment of collaboration relations in innovation networks.Meanwhile,the degree centrality of innovation entities and the transitivity of local knowledge networks have a negative effect on the formation of collaborative innovation networks.Finally,this paper proposes some suggestions for stimulating collaboration and innovation in domains.
