With Core Journal of Peking University, CSSCI and CSCD in CNKI Chinese database as the data source, a knowledge map is made by CiteSpace visualization software. This paper sorts out the changes in the domestic studies on digital currency from 2002 to 2021 including publication trend, keyword distribution, author cooperation, and institutional cooperation with the method of co-occurrence analysis, cluster analysis and mutation detection algorithm analysis. The result shows that now researches on digital currency, still early in its development trajectory, focus on political norms, attribute classification, technology research and development, and economic impact. In the future, the application, credit norms, technological innovation, and value assurance will continue to be the key research topics on digital currency. |
