At the same time, according to the statistics of the number of international papers cited, China ranks first in the world in four fields such as materials science, chemistry, computer science and engineering technology; the number of international top journal papers in China has risen by 2 to rank 2nd in the world; and the number of highly cited papers and hot papers in China continues to rank 2nd in the world.
The main highlights of the newly released "2021 China Science and Technology Papers Statistical Report" include the following 8 aspects:
——The overall output of China's outstanding scientific and technological papers continued to grow. In order to guide the scientific and technological management departments and scientific researchers to change from focusing on the number of papers to paying attention to the quality and impact of papers, and to stimulate original innovation, researchers are encouraged to publish international high-level papers, and excellent papers published in domestic journals in China are also emphasized. China's outstanding scientific and technological papers are composed of papers published internationally and domestically by Chinese researchers.
In 2020, There were a total of 493,800 outstanding scientific and technological papers in China, an increase of 27.6% over 2019, of which 246,000 were excellent international scientific and technological papers and 247,800 were outstanding domestic scientific and technological papers. The disciplines with the largest number of outstanding papers are clinical medicine, chemistry, electronics, communications and automatic control, biology.
According to the statistics of the number of international papers cited, China ranks first in the world in four fields such as materials science, chemistry, computer science, and engineering technology, and the field of computer science has increased compared with the previous year. From 2011 to 2021, 10 disciplines in China produced more than 20% of the world's papers. Papers in the four fields of materials, chemistry, computer science and engineering technology are ranked 1st in the world in terms of citations, and papers in 10 fields such as agricultural sciences, biology and biochemistry, environment and ecology are ranked 2nd in the world.
——The number of papers in the top international journals ranked second in the world, up 2 places. In 2020, there were 15 international journals with more than 100,000 citations and an impact factor of more than 30, with a total of 25,500 papers, of which China published 1,833 academic papers and review articles, ranking second in the world, up 2 places from 2019.
——The number of highly cited papers and hot papers continues to rank second in the world. As of September 2021, the number of highly cited papers in China was 42,900, accounting for 24.8% of the world share, an increase of 15.5% over 2020, and the world ranking remained in the second place, accounting for nearly 2 percentage points in the world share. The number of hot papers in China is 1515, accounting for 36.3% of the world total, an increase of 10.2% over 2020, and the world ranking remains in the second place.
The number of international co-authored papers in China continues to grow. Among the international papers published in China in 2020, the number of international co-authored papers was 144,500, an increase of 14,400 over 2019, an increase of 11.1%. International co-authored papers accounted for 26.2% of the total number of papers published in China. International co-authored papers with Chinese authors as first authors account for 69.3% of all international co-authored papers in China, with partners covering 169 countries and regions.
Among the papers published by Chinese authors in 2020, there are 485 papers with more than 100 authors and more than 50 cooperative institutions, covering topics such as particle and field physics, astronomy and astrophysics, multidisciplinary physics research, nuclear physics research, etc.
——The number of Chinese scientific and technological journals entering the forefront of this discipline in the world has increased, and the degree of international display has been further enhanced. In 2020, the SCI database (Science Citation Index) included 225 Chinese scientific and technological journals, an increase of 17 over 2019; the Ei (Engineering Index) database included 229 Chinese scientific and technological journals; and the Medline (Medical Index) included 136 Chinese scientific and technological journals.
In 2020, there were 18 Chinese journals in the top quartile of the total citation frequency in this subject area (Q1 area), an increase of 2 over 2019, and 85 journals with impact factors entering the Q1 region, an increase of 16 over 2019.
——The influence of China's scientific and technological journals has increased. According to the 2021 "Citation Report of China Science and Technology Journals" and the statistics of China Science and Technology Papers and Citation Library (CSTPCD), in 2020, CSTPCD included 1952 Chinese journals and 132 English journals in the field of natural sciences in China, and published 451,600 papers with Chinese authors as the first author. It includes 397 kinds of journals in the field of social sciences and publishes 50,000 papers with Chinese authors as the first author.
According to the 2021 China Science and Technology Journals Citation Report, the average impact factor of China's core scientific and technological journals is 0.869, with an average annual growth rate of 6.5% since 2001; the average total frequency of journals is 1523 times, with an average annual growth rate of 9.4% since 2001, and the academic impact level of scientific and technological journals has been significantly improved.
——"F5000 Platform" pushes Chinese excellent papers and Chinese authors to the world, and its international influence has been further expanded. In order to effectively improve the overall level of Chinese scientific and technological journals, better publicize and promote China's outstanding academic achievements, and carry out international academic exchanges. Using a combination of scientific quantitative indicators and peer review, CITIC Institute selects outstanding academic papers Chinese every year, and builds the "Leader 5000 - China Top Academic Paper Platform for Fine Scientific and Technological Journals (F5000)", which focuses on displaying and exchanging China's outstanding academic papers in the form of long abstracts in English. Through cooperation with important international information service institutions and international publishing institutions, the papers are centrally linked and accurately pushed to international counterparts. Provide an efficient channel for Chinese published papers, authors and Chinese academic journals to integrate into the international academic community.
At present, the "F5000 platform" has obtained 6.9489 million searches, attracting international users from more than 140 countries such as the United States, Russia, and Canada. International visitors are mainly from international universities and scientific research units, such as Cornell University, Harvard University, etc., the University of Cambridge, the University of London, the University of Oxford, etc., as well as some famous national laboratories.
It is understood that since 1987, CITIC Has been undertaking the statistical analysis of the publication of papers by Chinese scientific and technological personnel at home and abroad, and regularly publishes the overall analysis report of China's scientific and technological paper output every year, and on this basis, it has expanded to the statistical analysis of China's situation in the fields of scientific and technological journals, patent output, academic book publishing and other fields.
CITIC said that based on the new development stage, the implementation of the new development concept, the construction of a new development pattern, and the promotion of high-quality development, it is necessary to deeply implement the strategy of rejuvenating the country through science and education, the strategy of strengthening the country with talents, and the innovation-driven development strategy, improve the national innovation system, accelerate the construction of a scientific and technological power, and achieve a high level of scientific and technological self-reliance. As one of the important outputs of original innovation, the role of scientific and technological papers in the scientific and technological evaluation system should be adjusted to guide researchers to publish high-quality academic achievements. Therefore, the Institute actively explores the development of excellent paper evaluation research, focusing on the contribution and impact of high-quality scientific research results. (End)
