Chinese mainland has nearly doubled its share of highly cited researchers in four years, according to Clarivate Plc, a global leader in providing solutions to accelerate the life cycle of innovation.
The 2021 list of Highly Cited Researcher was unveiled by Clarivate in London, on November 16. The methodology that determines the "who's who" of influential researchers draws on the data and analysis performed by bibliometric experts and data scientists at the Institute for Scientific Information at Clarivate.
The annual list identifies 6,600 researchers from across the globe who demonstrated significant influence in their chosen areas of expertise through the publication of multiple highly cited papers during the last decade.
The Highly Cited Researchers' names are drawn after rigorous selection from publications that rank in the top one percent by citations for field and publication year in the Web of Science citation index, and the list identifies the research institutions and countries where they are based.
Researchers from more than 70 countries and regions have been recognized this year, including 3,774 in specific fields and 2,828 for cross-field impact.
Chinese mainland ranked the second this year, with 935 Highly Cited Researchers, or 14.2 percent, up from 7.9 percent in 2018.
There is a 1.8 percent loss in Highly Cited Researchers for the U.S. since last year and 3.6 percent since 2018. This contrasts with an increase of 6.3 percent for Chinese mainland since 2018.
The Chinese Academy of Sciences has 194 highly cited researchers, and ranked second highest among research institutions or organizations. In addition, with 58 highly cited researchers, Tsinghua University ranked the eighth highest among research institutions or organizations.
David Pendlebury, senior citation analyst at the Institute for Scientific Information, said, "The headline story is one of sizeable gains for the Chinese mainland and a decline for the U.S., particularly when you look at the trends over the last four years, which reflect a transformational rebalancing of scientific and scholarly contributions at the top level through the globalization of the research enterprise."
