This further confirms that China is now unequivocally the world's leading scientific power: according to Nature's latest rankings (the world's most authoritative scientific journal), half of the world's top 10 leading cities in science are in China, with Beijing and Shanghai respectively in number 1 and 2 position. If you expand to the top 50 cities, mainland China has 21 of them versus 13 for the US (source for the table: https://t.co/T5GfiKTeTb). The next country behind is the UK with 3 cities. As Nature notes in another article on this (https://t.co/P4PKgDCsbx), what's particularly interesting about the rankings is how so many of China’s smaller provincial capitals are becoming globally significant player in science. If you look at top 20 you can find: Nanjing (5th), Wuhan (9th), Hangzhou (13th), Hefei (15th) and Xi’an (20th) which now rank on par with major global cities, such as Tokyo (10th), Paris (11th), Seoul (12th) or London (14th). The speed of growth is also stunning, as the article explains: "the data indicate that these provincial cities — each anchoring regions as large and as wealthy, in relative terms, as a European country — are among those seeing the fastest-rising research output in the Nature Index."
