Journal impact factor, abbreviated as IF. The impact factor is one of the data cited in ISI (institute for scientific information) journals in the United States, and it is an internationally accepted journal evaluation index. The impact factor of a journal refers to the total number of citations of papers published in the first two years of the journal divided by the total number of papers published in the first two years of the statistical year.
The higher the IF of a journal, that is to say, the higher the citation rate of published documents, which on the one hand can explain how influential the research results of the journal's literature reports are, on the other hand, it can also reflect the academic level of the journal. Many famous academic journals will indicate their IF on their websites to show their influence in the corresponding disciplines. Of course, for the evaluation of a periodical, we can't just evaluate its quality by its IF.

4. Periodical ranking: Many academic institutions and databases rank periodicals according to impact factors, which directly affects their popularity and influence.
5. Allocation of funds: Many research funds and institutions will refer to the impact factors of journals when allocating funds, and journals with high impact factors are more likely to get financial support.
