Based on the citation of technological patents to literatures of scientific journals and the cooperation among the researchers, this paper builds the knowledge flow network from the angle of spatial dimension. Then employing the extensity centrality-Newman and the commonly used degree indexes, this paper excavates and analyses the nodes which occupy important positions among communities in the knowledge flow network. After that, this paper puts forward suggestions on how to make full use of the key nodes’ role of bridge to promote knowledge flow from literatures of science and technology journals to technology patents.9 pagesengAttribution-NonCommercial-NoDerivatives 4.0 InternationalKnowledge Flows, Transfer, Sharing and Exchangeknowledge diffusion, network, key nodes miningConference Paper10.24251/HICSS.2018.533
