基于加权复杂网络的我国区域创新系统集聚特征研究

Research on the Cluster Features of China's Regional Innovation Systems:Based on the Weighted Complex Networks

借鉴复杂网络理论,参考加权集聚系数,从资金、技术和知识3个维度分析我国区域创新系统的集聚特征。研究发现,我国区域创新系统的集聚模式体现出多元化特征,不同创新要素的集聚模式不同;区域创新系统集聚程度的空间差异明显,表现为空间正相关且以低低正相关为主,从局部特征看,极化现象与外溢现象并存。

The article utilized the complex network theory and used of weighted clustering coefficient, measured the ag-glomeration extent of china＇s regional innovation systems from capital, technology and knowledge dimensions and analyzedthe cluster features of them. The main conclusions are as follows： the cluster model of regional innovation system reflectsthe diverse characteristics, there are different models for different innovative elements; the spatial distribution of agglom-eration presents the global positive correlation,but the main type is low-low, from the local index, polarization phenome-non and spillover phenomenon coexist.
