Impact factor is an important index to measure the influence of academic journals and plays an important role in the evaluation of papers. The calculation method of the impact factor is to divide the number of citations of papers published in the last two years by the total number of papers published in the last two years. The higher the impact factor, the greater the influence of the journal, and the more times the papers published in the journal are cited.

The influence of impact factors on the evaluation of papers is mainly reflected in the following aspects:

1. Reflects the academic value of papers: Journals with higher impact factors usually have higher academic level and influence, and papers published in these journals often have higher academic value. Therefore, the impact factor can be used as a reference index to measure the academic value of the paper.

2. Improve the discoverability of papers: Journals with high impact factors are usually more likely to be concerned and cited by academic circles, and papers published in these journals are more likely to be discovered by other researchers. This is of great significance to the dissemination and promotion of the paper.

3. Promote academic exchanges and cooperation: Journals with high impact factors will often attract more outstanding scholars to contribute and review manuscripts, which will help promote academic exchanges and cooperation and improve the research level of the entire academic community.

4. It is conducive to the author's career development: publishing papers in high-impact journals can improve the author's academic reputation and is conducive to the author's academic development and career promotion.

5. Provide a basis for scientific research evaluation: As an important academic evaluation index, the impact factor is widely used in scientific research projects, talent selection, professional title evaluation and so on, which has a certain guiding role in scientific research evaluation.
