To build a new engine for national innovation driven economic growth is one of the overall development orientation of Beijing-Tianjin-Hebei. How to promote the flow of regional innovation elements，strengthen regional innovation cooperation and enhance the overall innovation ability of the region furtherly are important problems that urgently need to be solved. And deepening innovation collaborative governance is a critical way for Beijing-Tianjin-Hebei to solve these problems. On the basis of systemically combing the relevant theories of collaborative innovation governance，this paper makes an empirical analysis on the space network structure and the influencing factors of collaborative innovation in Beijing-Tianjin-Hebei by using the method of social network analysis. It can be concluded that：Beijing-Tianjin-Hebei has initially formed an innovation output spatial correlation network，with Beijing and Tianjin as the core，and Shijiazhuang，Baoding，Langfang as important nodes. The cohesion of the collaborative innovation network in Beijing-Tianjin-Hebei has been improved，but there is still room for improvement in the interaction between the subgroups. The difference in industrial structure between different parts of Beijing-Tianjin-Hebei is conducive to the spatial correlation to some extent. On this basis，the corresponding suggestions to deepen the innovation collaborative governance of Beijing-Tianjin-Hebei are put forward.
