Abstract:There are many university rankings over the world. Different university rankings may vary significantly on the guidelines, methodology and result. For the better use of the results, this paper takes two well-known world university rankings for comparative analysis. One is “World’s Best Universities” released by U.S. News & World Report, the other is “Webometrics Rankings of World Universities” published by Cybermetrics Lab which belongs to CCHS-CSIC at Spanish. From index system, data sources and results, the paper first analyses the two rankings respectively. Then the relationship between them is discussed. The results show that: the correlation between overall university competitiveness and web performance is not high. However, those universities performed better overall always rank ahead of others on the list of web ranking. “Webometrics Ranking”is an important complement to overall university rankings, and so on.
