Impact Factor (English: Impact Factor), abbreviated as IF, is a data in the Journal Citation Report (JCR) produced by Thomson Reuters.

That is, the total number of cited papers published by a journal in the first two years of the reporting year (JCR year) divided by the total number of papers published by the 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.

In the process of development, the influencing factors have formed two indicators: composite influencing factors and comprehensive influencing factors.

The comprehensive impact factor means that the comprehensive impact factor is calculated according to the comprehensive statistical source literature of periodicals, doctoral and master's dissertations and conference papers. The comprehensive impact factor refers to the comprehensive impact factor, which mainly refers to the integration of arts and sciences, and is calculated based on the comprehensive statistical source literature of scientific and technological journals and humanities and social sciences journals.

Both of them are based on the ratio of the total cited number of citable documents published in the first two years of the evaluated journals in the statistical year to the total cited number of citable documents published in the first two years of the journals.
