Compared with other citations, it is generally believed that self-citation is easy to be manipulated by authors or periodical editors, and is often given special respect. Therefore, in the evaluation of core journals, in order to highlight the position of other citation and eliminate the influence of self-citation literature, the index of other citation is especially increased. In fund application or academic evaluation, other citations of papers are often regarded as an important evaluation index. It is believed that the higher the citation rate, the better, while the self-citation of papers is generally not used as an evaluation index, or subconsciously thinks that self-citation is boastful.
The calculation formula of other citation rate is: total citation rate of other citations = citation times of other journals/total citation frequency of this journal.

Self-citation is inevitable in the editing and publishing process of SCI journals, and it is also a relatively normal phenomenon in academic circles. But generally speaking, the self-citation rate is higher than 30%.
If the self-citation rate of periodicals is too high, it is obviously abnormal, usually caused by human factors. Once the self-citation rate of journals is too high, there is a potential risk of being formally excluded from the SCI list. There are usually many reasons why SCI journals are suppressed, and high self-citation rate is one of them.
