Abstract: This study established the matrix of the new media research at home and abroad, such as key words co-words matrix and its correlation matrix and dissimilarity matrix through the methods of co-words analysis based on the retrieval of CNKI and Web of Science databases.And the relationship between key words was studied by cluster analysis and multidimensional scaling analysis.To do this, this research divided the domestic literatures into 5 clusters, which includes the communication model of new media and its social influence, the new media and internet plus, social media, the integration of traditional and new media, and the media form of new media etc., while the literatures abroad into 4 clusters, which includes social media, digital media and political participation, media convergence and the analysis and application of new media. And then, this article analyzed the maturity and centripetal degree of various clusters through the strategic coordinate analysis. Eventually, it also systematically combed the research contents of various clusters, which reflects the characteristics of discipline crossing and knowledge integration of new media research.

Key words: New media, Social media, Internet plus, Media integration, Co-words analysis, Bibliometrics
