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。 Based on the theory of media role and the theory of knowledge exchange, this paper analyzes the concept and algorithm of the three types of media roles cited by patent holders in the network and theoretically deduces whether the media role affects the ability of patentee's technology innovation and puts forward three hypotheses . Through empirical analysis, it is found that different roles have different degrees of influence: the intermediary centrism has the greatest influence on the patentee's technological innovation ability; the five kinds of bridge coefficients are less than the intermediary centrism, and the least influential one is the structural hole constraint.
