The introduction and cultivation of talents in colleges and universities are an important link of world-class university and discipline construction, as well as an essential index of university rankings at home and abroad. Talents are the main force of S&T innovation and research output in universities. They directly or indirectly influence the scores of university rankings. This paper made a correlation analysis between college talents indexes and university ranking scores based on Evaluation Report of Chinese Universities and Disciplines (2017-2018) from RCCSE and conducted the analysis according to the school level and type. The result is that all of the key universities have correlations with talent indexes, and the correlation of science and technology universities and colleges is significant, while the correlation of sports and art colleges is weak. Thus, talent introduction in key universities, cultivation of young talents in general universities and construction of talents team in other colleges are the effective method to advance the scores of university rankings.
