产学研合作网络小世界性、知识基础与企业创新

Industry-university-research Cooperation Network's Small-world、Knowledge Base and Enterprise Innovation

基于我国信息技术产业171家企业2007—2016年间申请并授权的专利数据,采用负二项回归模型实证检验反映产学研合作网络小世界性的两个指标——平均路径长度和聚集系数对企业创新的影响,以及知识基础宽度的调节效应。研究结果显示:较短的产学研合作网络平均路径长度有利于企业创新的提高,而网络聚集系数与企业创新呈倒U型关系;知识基础宽度正向调节平均路径长度与企业创新的负向关系,负向调节聚集系数与企业创新的倒U型关系。

Using the patent data of 171 enterprises in Information Technology （IT） industry from 2007 to 2016, this paper uses negative binomial regression model, empirically tests the influence of the shorter average path length and clustering coefficient of the industry-university-research cooperation network＇s small-world on enterprise innovation, and the moderating effect of knowledge base. The results show that the shorter average path length is beneficial to the improvement of enterprise innovation, but the impact of clustering coefficient on the enterprise innovation in an inverted-U curvilinear way. The knowledge base width moderates positively the effect of average path length on the enterprise innovation, but moderates negatively the effect of clustering coefficient on enterprise innovation.
