Abstract Urban networking is the inevitable result of the development of urban agglomeration to the advanced stage, and innovation network is an important support to improve regional innovation ability.Based on the research object of Beijing-Tianjin-Hebei urban agglomeration,the paper analyzes the structural characteristics and spatiotemporal evolution of the innovation network by using social network analysis method,Ucinet and ArcGIS software, and then explores the driving mechanism of innovation network evolution of Beijing- Tianjin-Hebei urban agglomeration.The research results show that:(1)The innovation network density of Beijing-Tianjin-Hebei city cluster is constantly increasing and the inter-city innovation connection is significantly strengthened;(2)The innovation network of Beijing-Tianjin-Hebei city cluster has evolved from the single core in the early stage to the"1+2"spatial pattern in the middle stage,with Beijing as the core and Tianjin and Shijiazhuang as the fulcrums, to the"multi-center and multi-level"pattern in the middle and later stage;(3)The non-parametric empirical analysis of QAP reveal that geographical proximity and institutional proximity have a positive effect on inter-city innovation cooperation, while knowledge base proximity plays a negative role.Economic proximity and cognitive proximity only exerts driving impact on innovation cooperation in the early stage.
