China tops U.S. in quantity and quality of scientific papers
Report finds rapidly expanding Chinese research footprint while Japan falters
TOKYO -- China now leads the world both in the number of scientific research papers as well as most cited papers, a report from Japan's science and technology ministry shows, which is expected to bolster the competitiveness of its economy and industries in the future.
Research papers are considered higher quality the more they are cited by others. Chinese research accounted for 27.2%, or 4,744, of the world's top 1% of most cited papers, overtaking the U.S. at 24.9%, or 4,330. The U.K. came in third at 5.5%.
The ministry's National Institute of Science and Technology Policy compiled the report based on data from Clarivate Analytics. The figures represent 2019 levels, based on the annual average between 2018 and 2020 to account for fluctuations in publication numbers. The report was released Tuesday, the same day U.S. President Joe Biden signed into law the CHIPS and Science Act, a $280 billion bill framed as essential to winning economic competition with China through greater research.
Scientific research is the driver behind competitive industries and economies. Current research capabilities will determine future market shares in artificial intelligence, quantum technology and other cutting-edge fields, and may have a direct impact on national security as well.
China has quickly increased its footprint in advanced research in recent years. It overtook the U.S. in the total number of scientific papers in the 2020 report, then in the number of top 10% most cited papers in the 2021 report.
China published 407,181 scientific papers in 2019 according to the latest report, pulling further ahead of the U.S. at 293,434. In terms of the top 10% most cited papers, China accounted for 26.6% of publications, while the U.S. accounted for 21.1%.
"China is one of the top countries in the world in terms of both the quantity and quality of scientific papers," said Shinichi Kuroki, deputy director-general of the Asia and Pacific Research Center at the Japan Science and Technology Agency.
"In order to become the true global leader, it will need to continue producing internationally recognized research," he said.
Meanwhile, Japan is falling behind. It ranked fifth in the total number of publications and 10th in the top 1% most cited papers in the latest report after losing ground to India. It dropped to 12th place in the number of the top 10% most cited papers, passed by Spain and South Korea.
The number of universities in India have increased roughly 4.6 times from 243 in 2000 to 1,117 in 2018. Over two million receive a bachelor's degree in the sciences each year. In contrast, research Japan has slowed since the mid-2000s with no recovery in sight, stoking concerns about the effect on the country's economy and industries.
