On June 30, Clarivate announced the latest SCI Impact Factor (IF) for 2021
Due to the implementation of the new impact factor algorithm, all journals have seen a significant increase this year
In fact, almost all forecasts of CA impact factor have remained high in recent years, but it has risen from 292 points by more than 200 points in just one year, which can be said to be the first time in the past ten years
In addition to CA, the top four medical journals NEJM, The Lancet, JAMA and BMJ also have good impact factors.
The impact factors of the four world-renowned journals, Nature, Science, Cell, and PNAS, have also been greatly improved
In addition, the impact factors of domestic journals have also risen to varying degrees
