摘要
文章基于联合发明专利数据构建长三角城市群产学研创新合作网络,运用社会网络分析方法和固定效应的负二项回归模型对其拓扑结构演化特征和影响机制进行了分析。结果表明:(1)长三角城市群产学研创新联系日渐紧密,网络规模和密度稳步提升;(2)网络枢纽节点增多,次中心节点减少,边缘节点数量居高不下;(3)长三角城市群产学研合作创新网络由“Z”字形结构向以合肥、南京、上海等为核心的多中心“星型”放射状空间格局演变,网络联系层级性显著;(4)制度邻近、认知邻近对产学研创新合作网络具有正向影响,地理邻近发挥负向作用,不同邻近性对长三角产学研创新合作网络的影响具有协同促进效应。
Based on the joint invention patents,this paper constructs the industry-university-research innovation cooperation network,and analyzes its topological evolution characteristics and influence mechanism using the social network analysis method and the negative binomial regression model of fixed effects.The results show that:1)The industry-university-research innovation connection has become increasingly close in the Yangtze River Delta urban agglomeration,the scale and density of its network both have steadily increased.2)The number of its network hub nodes increases,the number of its sub-central nodes decreases,and its edge nodes remain high.3)The industry-university-research cooperation innovation network of the Yangtze River Delta urban agglomeration has evolved from the"Z"structure to the multi-center radial spatial pattern which takes Hefei,Nanjing and Shanghai as the cores,the network connection hierarchy is significant.4)Institutional proximity and cognitive proximity have a positive impact on the industry-university-research innovation cooperation network,while geographical proximity plays a negative role.The influence of different proximity on the industry-university-research innovation cooperation network in the Yangtze River Delta has a synergistic promoting effect.
