Abstract: 【Purpose/significance】The relationship between the number of authors and the citation frequency is a traditional issue,
and research conclusions have been controversial, this article attempts to end this discussion.【Method/process】Based on the theoreti?cal analysis of the relationship between the number of authors and the citation frequency, this paper puts forward the concept of impact factor of the number of authors. Taking the 2019-2020 version of the CSSCI Economics Journal as an example, based on the CNKI ci? tation database, regression analysis, quantile regression and one-way ANOVA are used to study comprehensively.【Result/conclusion】The results show: Scientific research cooperation does not mean that the more authors, the greater the impact of the paper; the citation frequency has nothing to do with the number of authors. There are significant differences in the impact factor of the number of authors with different numbers of authors. The former is viewed from a microscopic perspective, and the latter is viewed from a macroscopic perspective. The two are not contradictory.【Innovation/limitation】The research method on the relationship between the citation fre? quency and the number of authors needs to be improved
