Digital economy has become a research hotspot in academia nowadays. However, the systematic and quantitative review of digital economy is still blank. Therefore, the periodical literature of domestic digital economy is systematically sorted out and analyzed, hoping to provide some reference for researchers in this field. Taking 971 Chinese periodical papers retrieved from the full-text database of Chinese periodicals from 1998 to August 1, 2019 as data sources, taking Bibliometrics as the main research method, and using visualization software CiteSpace, data mining and standardized processing of Periodical Documents in this field are carried out to make them visible. It describes the origin and internal relationship of high-frequency Keywords, reveals the research hotspots and evolution process in this field since its emergence, and finally puts forward the corresponding prospects.
