Abstract: To analyze the hotspots and trend of the study on global transgenic maize, the paper collected literature on transgenic maize from 2005 to 2015 which are included in the core journals in the database of Web science as samples and used Citespace for visual analysis of mapping knowledge domain of studies on transgenic maize, based on the bibliometric method. As a result, 2701 pieces of documents have been sifted out from 2851 pieces of documents which have been retrieved according to the search strategy, the literature are in a stable situation and show a tendency of increase. The paper analyzed the scientific knowledge graphs on co-authors analysis network, co-institutions analysis network, author co-citation analysis network, citation analysis network and keyword co-appearance network by using Citespace software. Therefore, in cluster analysis, it is found that in the study on transgenic maize, Chinese scholars and institutions hold an advantage in quantity while the citation of foreigners’ literature is higher than Chinese. Besides, the focus of global research is mainly about flora, genes, protein and resistant, etc.
