基于多维邻近性的新兴技术创新超网络演化研究——以新能源汽车产业为例

Evolution of Emerging Technology Innovation Hypernetwork Based on Multidimensional Proximities--Based on New Energy Automobile Industry

本文引入地理邻近和技术邻近的交互作用,形成多维邻近与超度组合择优连接机制,构建了新兴技术创新超网络演化模型。通过数值仿真揭示其演化规律,结合我国新能源汽车技术创新网络进行实证分析。结果表明:(1)多维邻近与超度组合择优连接机制共同作用于新兴技术创新超网络演化,过程中新兴技术创新超网络小世界特征逐渐减弱,无标度特征持续存在;(2)超网络中旧节点重连组成超边占全部超边的比重较大时,合作创新关系的形成中多维邻近择优连接发挥的作用越大,网络整体创新合作越均衡;(3)超网络中新旧节点相连组成超边占全部超边的比重较大时,合作创新关系的形成中超度择优连接发挥的作用越大,核心节点创新活动的作用更加凸显。

This paper proposed the concept of innovation hypernetwork,formed two preferential attachment mechanisms of multidimensional proximities and hyperdegree,constructed an evolving innovation hypernetwork model.The numerical simulations and empirical analysis on the cooperation innovation network of new energy automobile industry in China.The study found that:(1)innovation hypernetwork always displaied scale-free structure characteristics under the combination of the two preferential attachment mechanisms,the small-world structure characteristics of the network have gradually weakened;(2)when the proportion of old nodes reconnected in the hypernetwork was larger,multidimensional proximities preferential attachment mechanism in the formation of cooperative innovation relationship will lead to the overall cooperative innovation of the hypernetwork was more balanced;(3)when the proportion of new and old nodes connected to each other in the hypernetwork was larger,hyperdegree 1><88f4><preferential attachment mechanism in the formation of cooperative innovation relationship will lead to the role of core nodes innovation activities in the hypernetwork was more prominent.
