That is, the total number of cited papers published in a journal in the first two years of the reporting year (JCRyear) divided by the total number of papers published in this journal in these two years. This is an internationally accepted periodical evaluation index.
The impact factor has become a general index of periodical evaluation in the world. It is not only an index to measure the usefulness and exhibition of periodicals, but also an important index to measure the academic level of periodicals and even the quality of papers. The influence factor is a relative statistic.
To query the impact factors of foreign periodicals, we can use JCR(JournalCitationReports) in the foreign language database WebofScience, in which JCRScienceEdition is used to query natural science periodicals and JCRSocialSciencesEdition is used to query humanities and social science periodicals. ?
