The National Taiwan University Ranking, also known as the Performance Ranking of Scientific Papers for World Universities, has been published since 2007. It is a straightforward research-based ranking that uses a stable and consistent methodology with eight indicators that measure research productivity (25%), impact (35%) and excellence (40%).

The indicators are:

• Number of articles published over eleven years
• Number of articles published in the current year
• Number of citations over eleven years
• Number of citations over two years
• Average number of citations over eleven years
• H-index over two years
• Number of highly cited papers over eleven years
• Number of articles in the current year in high impact journals.

These rankings provide further evidence of the remarkable growth of leading Chinese universities between 2007 and 2020 especially in chemistry and engineering. In contrast, major Japanese and Indian universities have stagnated or slipped down the tables. The Indian Institute of Science fell from 433^rd place to the 501-550 band while the University of Tokyo has fallen from 13^th to 37^th place.

The field and subject rankings indicate that China has acquired a dominating position in the natural sciences and technology.  The case of computer science is especially noteworthy. Tsinghua University is in first place and of the top ten nine are now in Mainland China. The exception is Nanyang Technological University in Singapore.

The current top five universities overall are:

1. Harvard University
2. Stanford University
3. University of Toronto
4. Johns Hopkins University
5. University College London.

The top university in the field rankings are:

Agriculture; Wageningen University

Engineering; Tsinghua University

Life Sciences; Harvard University

Medicine; Harvard University

Natural Sciences; Tsinghua University

Social Sciences; Harvard University
