Under the wave of globalization and informatization, museums are also moving towards to digitalization and intellectualization. Using the key words of digital literature research in CNKI as the data source, and employing the co-word clustering method, this study resulted in 12 research directions of digital museum research in China, and visualized them through knowledge map and strategic graph. The study showed that “Collection management and digital construction” and “Digital display and interaction” are the research hot points in the field of digital museum research; the research of “Smart museum” is self-contained, which may needs to build integration with other research fields to form new research points. Although some research directions have started, such as “The status quo and problems of digital museum construction”, “Digital museums help protect and inheritance”, “Application of digital technology in various museums”, “Museum information communication”, “Digital protection of cultural heritage”, “New media and museum culture communication”, “Museum construction in the context of the ‘Internet +’ era”, “Research on digitalization of cultural relics”, “Construction of metadata standardization”, their development is at primary stage, and need further improvement.
