以创新网络结构—绩效为研究对象,分析结点属性、联系强度及网络中介位置等网络结构要素对创新网络绩效的作用。运用科研合作网络表示创新网络,以燃料电池为研究领域,将1989—2011年间中国学者合作发表在SCI来源期刊上的科技论文作为样本数据,利用UCINET6绘制中国区域科研合作网络图谱并获取网络结构的表征,验证结点属性、联系强度和中介位置等对创新绩效的作用机制及效果。研究结果表明:当分别考察结点属性、联系强度和网络中介位置等网络结构要素对创新绩效的作用时,它们均对创新绩效存在显著的促进作用;考察三者互动效应对创新绩效的作用时,中介位置对创新绩效不存在直接影响,而是借助联系强度间接促进创新绩效的提升。
Taking innovation network structure-performance as the research object, it analyzes the role of network structural elements such as node attributes, contact strength, and network intermediary positions on innovation network performance. Using the research cooperation network to express the innovation network, taking the fuel cell as the research field, using the scientific papers published by Chinese scholars in the SCI source periodicals from 1989 to 2011 as sample data, using UCINET6 to draw the map of the China regional scientific research cooperation network and obtaining the network structure. Characterizing and verifying the effect mechanism of node attributes, contact strength, and intermediary position on innovation performance and its effects. The results of the research show that: when examining the effects of network structure elements such as node attributes, connection strength, and network mediation on innovation performance, they all have a significant role in promoting innovation performance; when the interaction effects of the three interaction effects on innovation performance are examined The position of the intermediary does not directly affect the innovation performance. Instead, it uses the strength of contact to indirectly promote the improvement of innovation performance.
