珠三角电子信息产业集群创新网络时空演化特征分析

Research on the evolution of the innovation network of the electronic information industry in the Pearl River Delta

文章运用社会网络分析方法,以珠三角电子信息产业集群作为研究对象,采集2000年至2019年产业联合申请发明专利数据,构建四阶段珠三角电子信息产业集群创新网络,从网络拓扑结构和空间结构变化视角分析集群创新网络演化历程,深入探讨电子信息产业集群创新网络多尺度时空演化特征,得出以下结论:(1)珠三角电子信息产业集群创新网络整体规模扩大,但网络紧密度不足,网络发展呈现“小世界”特征。(2)网络核心节点由外资企业向本地高校科研机构及龙头企业转变。(3)珠三角内部空间创新联系不断增强,网络空间格局由“核心—边缘”结构向多核心发展转变。(4)国家层面形成从东向西创新合作联系层级逐步递减的网络空间合作格局。

Under the background of the development of knowledge economy era,innovation cooperation presents a networked development trend.Innovation network has become a new engine for the development of industrial clusters,promoting industrial transformation and upgradation and high-quality development of regional economy.Using the method of social network analysis,this paper takes the electronic information industry cluster in the Pearl River Delta as the research object,collects the data of industrial joint application for invention patents from 2000 to 2019,constructs a four stage innovation network of the electronic information industry cluster in the Pearl River Delta,analyzes the evolution process of the cluster innovation network from the perspective of network topology and spatial structure changes,and deeply discusses the multi-scale space-time evolution characteristics of the innovation network of the electronic information industry cluster.The conclusions are as follows:(1)The overall scale of the innovation network of the electronic information industry cluster in the Pearl River Delta has expanded,but the network density is insufficient,and the network development presents the characteristics of"small world".(2)The core nodes of the network have been transformed from foreign-funded enterprises to local universities,scientific research institutions and leading enterprises.(3)The spatial innovation linkages within the Pearl River Delta have been continuously strengthened,and the structure of the network spatial pattern has changed from"core edge"to multi-core.(4)At the national level,a pattern of network spatial cooperation has been formed,with the level of innovation cooperation gradually decreasing from east to west.
