Using social network analysis, spatial econometric method and structural equation model, based on the patent citation data of China’s marine industry from 2008 to 2019, this paper analyzes temporal-spatial characteristics influencing factors knowledge spillover Industry in China. The results show that: with Qingdao, Beijing Shanghai as main distribution centers has expanded rapidly, status Zhoushan, Wuhan other cities improved significantly. space structure tends be multi-core complex, extending coast inland; There are significant differences cyberspace. central western regions low value areas, while eastern region is core area, have built an “X” shaped Qingdao intersection; Knowledge proximity, cognitive proximity economic important that affect networks. Geographic a reinforcing effect proximity. This beneficial it provides reference experience for innovation high-quality development economy by effectively analyzing spatio-temporal diffusion network.
