The selection of SCI core journals is very strict.

The evaluation mechanism of SCI journals is mainly to evaluate the quality and influence of published papers. Papers published in SCI journals have high recognition, which can improve the possibility of the author's research results being cited by other scholars, and can also provide reference for the promotion evaluation, professional title evaluation and qualification certification of scientific researchers.

In academic circles, SCI indicators are widely used in the appropriate transformation of scientific and technological achievements, scientific and technological innovation and application, and evaluation of academic achievements. Some universities even rank their academic level by the number of published SCI papers, while scientific research institutions measure their innovation ability and academic strength by the number of published SCI papers. SCI widely collects and deploys global scientific and technological information, promotes the extension and dissemination of information in academic fields, and provides reliable support and basis for scientific research, which is the goal pursued by many researchers.
