On high quality academic output, who is the best in Chinese universities?
Nature's latest recognition, (still) China University of science and technology.
In the newly released nature index university rankings, the Academic Ranking of China University of science and technology ranks first in China.
In the global school / institution, it ranks the 9th, behind the University of Tokyo, and it is superior to Oxford University.
What you may not know is that this is the title of China University of science and technology, which has won the first place in Chinese universities for many times in a row.
In addition, the CAS system is also the biggest winner in the nature index,Chinese Academy of SciencesFor eight consecutive years, it has ranked first in scientific research output in the world.
Let's take a complete look at the 2020 nature index ranking released this time.
China University of science and technology won the first place in Chinese Universities
First of all, let's look at the situation of domestic universities.
Without considering the non university research institutions, the top five universities in China are * * (in order of ranking)
University of science and technology of China, Peking University, University of Chinese Academy of Sciences, Tsinghua University and Nanjing University.
However, there is little difference in the scores of the five universities.
China University of science and technology is the ninth in the world, while Peking University, the University of the Chinese Academy of Sciences, Tsinghua University and Nanjing University are 12, 13, 14 and 15 respectively.
Among them, the number of papers (count) of National University of science and technology is the largest, with the largest number2475Papers dominate the domestic list.
In the annual list released last year, the University of science and technology is also the fastest growing academic institution, with a 242% increase in thesis scores from 2015 to 2019.
In terms of quality, the University ranked first in China with 1305 papers and a total score of 467.07, and its total output of high-quality scientific research papers almost doubled compared with 2015.
According to the monthly updated ranking of nature index, since the first time that China University of science and technology has been a university in March 2020, it has never stepped down from the altar.
The top 6-10 are Zhejiang University, Shanghai Jiaotong University, Fudan University, Sun Yat sen University and Nankai University, all of which are traditional famous universities.
Sichuan University and Wuhan University got the best results in history, ranking 11th and 12th in China, and 47th and 48th in the world.
The rise of South University of science and technology is also very obvious.
Only in May last year did it enter the top 100 in the world for the first time, ranking 99th. Now, just seven months later, the ranking has advanced nearly 50, ranking 52nd in the world with 207.56 points.
It is worth noting that Tongji University is among the top 100 in the world for the first time.
In addition, Lanzhou University, which has been neglected by universities for many times before, was renamed by nature this time, and Lanzhou University has entered the top 30 universities / institutions in China's academic field.
Global comprehensive ranking: Chinese Academy of Sciences ranks first, surpassing Harvard
The ranking analyzed above is the highest in the world under the nature indexcolleges and universitiesRanking.
The comprehensive ranking of nature index includes not only universities but also various scientific research institutions.
In fact, since the first launch of the nature index in 2014, the score of CAS has been ranked first in the world in the annual report.
And from the number of papers (count) or score measurement (share) calculation, the Chinese Academy of Sciences is the first.
Among them, the scores of many research institutes are even higher than those of the middle and lower ranking universities on the list.
In the final report, the number of papers and scores of the Chinese Academy of sciences are even more than twice that of Harvard University.
Last year, 17 Chinese universities / institutions entered the top 100. In recent years, the number of Chinese research institutions on the list has been growing.
Is this growing fast? According to the data of nature, it is not fast, because from 2017 to 2018, the growth rate was as high as 15.4%, which was the best in the major countries / regions.
In addition to the old strong scientific research universities, there are many Chinese universities in the world's top 200 (FC score measurement).
In addition, there are also some emerging industries in recent yearsSuzhou University, ranking 61st, even surpassing the well-known Chinese and foreign universities such as Beihang, Tongji, Edinburgh University, etc.
Relatively low keyZhengzhou University, ranking 144, also surpassing such traditional famous universities as the Chinese University of Hong Kong, Dalian Polytechnic and Brown University.
And in all kinds of lists has been eye-catchingShenzhen UniversityThis time, it also entered the top 200, ranking 198.
First disclosure of AI field index, Tsinghua University ranks first in China
At the same time, the nature official also specially gaveartificial intelligenceThe 2020 nature index of the field.
This is the first time that nature has launched AI index, which calculates all papers published by various institutions from 2015 to 2019.
Among them, Harvard University, Stanford University and MIT are the top three in terms of share.
China's top scientific research institution is still the Chinese Academy of Sciences, ranking seventh.
The highest ranking university in China isTsinghua University, ranking 35th.
In addition to Tsinghua University and the nature index in the field of artificial intelligence, Peking University (43), the University of the Chinese Academy of Sciences (74), Beijing Normal University (82), Fudan University (96) and China University of science and Technology (100) are also on the list.
In the top 100, Chinese universities / institutions account for 7 seats, second only to the United States.
In the top 100, there are 57 universities and institutions in the United States.
What is the nature index ranking?
Finally, let's talk about the list and its basis.
The nature index attempts to objectively measure the scientific output of institutions and countries, taking into account quality differences. It was first launched in November 2014 and updated monthly, listing more than 10000 institutions.
At present, it only counts articles published in 82 journals selected by the independent committee.
At present, the ranking covers journals in four research fields: Life Sciences, chemistry, physics and earth sciences. Each field is dominated by different research institutes.
It mainly consists of two calculation methods.
One is the number of papers (AC, count).
If authors from multiple institutions and / or countries / regions participate in a scientific article, assuming that all researchers participate equally in the article, then each institution / country participating in the article will get 1 point.
The other is thesis score (FC, share).
The total score of each paper is 1. If all authors participate in the article equally, the score will be shared. For example, if a paper has five authors, the FC score of each author is 0.2.
The nature index is updated to rank universities / institutions from November 1, 2019 to October 31, 2020.
