Fintech has been widely valued in practice, but in the research field, most of the researches focuse on specific technical areas in practice, which leads to the lack of theoretical research and empirical research. On the basis of Milian et al.[1], this paper reviews the domestic financial science and technology research with the help of Citespace software as the tool to draw the visualization of knowledge literate, and gives a preliminary comparative study. At the same time, it introduces the "value space classification framework", classifies and reviews the existing researches according to the concept research, analysis research, design oriented research and impact research, and finally concludes the shortcomings of the current researches, as well as the future research prospects. For the first time, this paper summarizes the same topic by combining quantitative visualization analysis and qualitative value space classification analysis which are consistent in epistemology.
