专利合作网络结构特征对企业探索式创新的影响——以航空装备制造企业为例

以航空装备制造企业为例，使用专利合作数据，通过社会网络分析方法和负二项回归分析研究专利合作网络结构特征对企业探索式创新的影响及知识基础在其中发挥的中介效应。研究结果表明度数中心度、结构洞与企业探索式创新呈显著正相关关系，知识基础在二者中发挥了部分中介效应的作用。因此，航空装备制造企业要积极扩大专利合作规模与频次，努力向专利合作网络中心位置发展；同时要拓展获取异质性知识的渠道，鼓励企业内知识交流，增强知识积累，促进企业探索式创新发展。

The Influence of the Structural Features of Patent Cooperation Network on Enterprise Exploratory Innovation: a Case Study of the Aviation Equipment Manufacturing Enterprises

Taking aeronautical equipment manufacturing companies as an example, using patent cooperation data, through social network analysis and negative binomial regression analysis, this paper studies the influence of the structural characteristics of patent cooperation network on enterprise exploratory innovation and the intermediary effect of the knowledge base in it. The research results show that degree centrality, structural holes and enterprise exploratory innovation are significantly positively correlated, and the knowledge base plays a part of the mediating effect between the two. Therefore, aviation equipment manufacturing enterprises should actively expand the scale and frequency of patent cooperation and strive to develop toward the center of patent cooperation network. At the same time, enterprises should expand the channels to obtain heterogeneous knowledge, encourage knowledge exchange within enterprises, enhance knowledge accumulation, and promote the development of enterprise exploratory innovation.
