Sci impact factor 5.0 shows that the level is already very high, journals have certain influence, and journals also have high value. However, we can't simply think that the higher the impact factors of journals, the better. Journals in different fields can't judge their level only by their impact factors.

Among many sci journals, there are many journals with impact factors exceeding 5, some with scores exceeding 10, and some with scores of 5- 10. In fact, the author can publish journal papers with an impact factor of about 5, which is considered excellent. Relatively speaking, the higher the impact factor of a journal, the more difficult it is to publish, so the author should choose a suitable journal to publish papers according to his own level.

Then the journals with high impact factors must have a higher level than those with low impact factors. This is not necessarily true. Journals of different disciplines cannot directly compare their influencing factors, for example, they are all SCI journals.

Medicine is generally higher than other disciplines. NEJM (New England Journal of Medicine), which is also known as the four major international medical journals with JAMA, has the latest impact factor of 72.406, which is nearly twice that of Science, but the quality of papers published in Science is also relatively high.

For another example, a material doctoral student in a middle school in China is required to publish an SCI paper with an impact factor greater than 6, while a computer doctoral student in Qingbei level can graduate if he can publish a paper with an impact factor of 1.2. Therefore, in the academic field, it is meaningful to compare the impact factors only for journals or papers in the same field. It is unscientific to measure the academic authority of journals in different disciplines with impact factors.

Of course, the influencing factors of sci journals are also dynamic. Ke Rui Wei 'an publishes the annual JCR in June every year, while the influence factor of Chinese Academy of Sciences is 65438+February every year. The impact factors of journals of different disciplines are quite different, so the impact factors cannot be used for the comparison of interdisciplinary journals. When selecting sci journals, the author should pay due attention to the influencing factors and comprehensively consider the appropriate sci journals, which is more conducive to the publication of papers.
