Beijing retained its position as the world's leading science city, a title it has held since 2016, according to a report by the Xinhua News Agency, which is subscribed to by Noticias Argentinas.
The recently published 'Nature Index 2025 Science Cities' supplement shows that the number of Chinese cities among the top ten increased from five in 2023 to six in 2024, marking the first time China holds a majority in the rankings.
'The movements of the cities reflect a broader trend in the China index that is increasing while the United States is losing ground,' the supplement highlights.
An in-depth analysis shows that Chinese cities have a strong advantage in chemistry, physical sciences, and environmental and earth sciences, holding the top world rankings in all three fields.
The contribution from Shanghai increased most significantly, by 20 percent.
Furthermore, the combined adjusted Share of all US cities within the top ten decreased.
Its analysis uses 'Share,' a fractional count that reflects the institutional contribution to publications, as the main metric, with time series data adjusted to 2024 levels. Each city's Share is calculated by summing the contributions of all affiliated institutions located within that city.
In the other two fields of study, they secured six of the top ten spots, and Beijing ranked first in the world in all three areas.
The supplement draws information from the Nature Index database, which tracks research articles published from 2015 to 2024.
