Abstract: In 1977, "Science of Science" (SciSci) was formally proposed in China as a social science to investigate scientific research activities and summarize the laws of scientific development. In the nearly half-century that followed, the study of SciSci in China under the Bernardine paradigm has undergone an evolutionary path from qualitative thinking to mathematical statistics and then to mapping knowledge domain. In 1980s, SciSci research of China was beginning to enter the scientometric phase through mathematical and statistical methods, thus it later became integrated into the international community. At the beginning of the 21st century, with the introduction of the concept of knowmetrics, the visualisation method of mapping knowledge domain took SciSci into its third phase. This paradigm evolution of SciSci could also be reflected as the development from the SciSci to the refinement of scientometrics in China.
