It should be noted that the divisions here ≠ the divisions of the Chinese Academy of Sciences , and the divisions here adopt the Thomson Reuters division method, that is, they are divided into four divisions in equal proportions according to the ranking of impact factors.
As for the zoning of the Chinese Academy of Sciences, as early as December last year, there was a major change in its zoning method. Instead of using the percentage zoning method in the above figure, it adopted the journal surpassing index (that is, the citation frequency of the papers in this journal is higher than the same Probability of other journals with the same topic and the same type of literature. This index is used to correct the limitations of previous journal impact factor calculations to better reflect the influence of journals).
Therefore, the impact factors and divisions released by Clarivate Analytics can only be used as a reference for domestic partners. The division of the Chinese Academy of Sciences in 2023 is likely to be different from the division here. You can refer to the 2022 division. The comparison between the Chinese Academy of Sciences division and the Thomson Reuters division.
