全球科研城市榜单出炉
Global science cities 2020 Beijing ranked as the top science city globally, followed by New York, Boston, San Francisco/San Jose and Shanghai, in the Nature Index global science city 2020 rankings. Four other Chinese cities - Nanjing, Wuhan, Guangzhou and Hefei - ranked among the top 20 global science cities. David Swinbanks, founder of the Nature Index, said a concentration of talent, funding, research institutions and other resources is crucial for the top five global science cities to maintain their leading positions. A key metric used by the index is "share" - a city's contribution to science publication in its own country. Data shows Beijing's contribution to China was 21%, more than double that of any other city in the top five. Beijing is also home to the Chinese Academy of Sciences, which, at the institutional level, leads the index in share and acts as a central hub of Chinese scientific collaboration. |
