Global production of scientific papers hit an all-time high this year, estimates show, with emerging economies rising fastest.
Emerging economies showed some of the largest increases in research output in 2018, according to estimates from the publishing-services company Clarivate Analytics. Pakistan and Egypt topped the list in percentage terms, with rises of 21% and 15.9%, respectively.
China’s publications rose by about 15%, and India, Brazil, Mexico and Iran all saw their output grow by more than 8% compared with 2017 (See ‘Countries with biggest rises in research output’).
Globally, research output rose by around 5% in 2018, to an estimated 1,620,731 papers listed in a vast science-citation database Web of Science, the highest ever (see ‘Research output rose again in 2018’).
This diversification of players in science is a phenomenal success, says Caroline Wagner, a science and technology policy analyst at Ohio State University, and a former adviser to the US government.
“In 1980, only 5 countries did 90% of all science — the United States, the United Kingdom, France, Germany and Japan,” she says. “Now there are 20 countries within the top producing group.”
