摘要
对专利权人引用网络中的3种类型的媒介角色的概念、算法等进行梳理,根据媒介角色理论和知识交流理论对媒介角色是否影响专利权人技术创新能力做理论推导,并提出3个假设。通过实证分析发现,不同的角色影响程度各不相同:中介中心性对专利权人技术创新能力的影响力最大;5种桥系数小于中介中心性,影响最小的是结构洞约束。
The concepts and algorithms of three types mediation roles including betweenness centrality,brokerage structure and structural hole in assignees citation network are analyzed, and the functions of mediation roles to assignees technology innovation are deducted theoretically based on the mediation theory and knowledge communication theory, then three hypotheses are proposed. Through empirical study,it is found that the influence degrees are different：the influence of betweenness centrality to assignee technology innovation is the strongest, then the five brokerage indexes, and the weakest influence degree is structural hole.
