To query the impact factors of foreign periodicals, we can use JCR(Journal Citation Reports) in the foreign language database Web of Science, in which JCR Science Edition is used to query natural science periodicals and JCR Social Science Edition is used to query humanities and social science periodicals. ?

Influencing factors:
From the calculation formula, although the impact factor is only directly related to the number of citations and papers, it is actually closely related to many factors. There are five main factors that determine the size of influencing factors:
Thesis factors. For example, the delay in publication, the length and type of the paper, and the number of collaborators. Journals with shorter publication time lag are more likely to obtain higher impact factors.
If the publishing cycle is long, due to the aging of the literature (more than 2 years), a considerable number of citations are not counted, that is, they do not participate in the calculation of the impact factor, thus reducing the impact factor. A large number of statistical data show that if the published papers are hot topics, and the length is short and published quickly, the citation rate will soon reach the peak, leading to a rapid increase in the impact factors of journals, and then a rapid decline.
Journals that publish complete research papers are cited for a long time, and the impact factors rise for a long time. Some data also show that there is a significant positive correlation between the average number of authors and the total cited frequency of papers.
