In the 'Nature Index' rankings, a key indicator of national scientific research capabilities, China has maintained the top position for three consecutive years, further widening the gap with the United States.
While the U.S. has blocked exports of advanced semiconductors to China and restricted science and technology exchanges, China’s scientific research output has surged.
As scientific paper achievements are a leading indicator of future commercializable technologies, some analyses suggest the balance of power in the U.S.-China tech hegemony competition is tilting toward China.
South Korea remained 7th in the national rankings, unchanged from last year, but no domestic institutions entered the top 50 in the organizational rankings. Seoul National University, the highest-ranked Korean institution, fell six spots to 58th place compared to last year.
◇China Secures 90% of Top 10 Research Institutions
Springer Nature, which publishes the international academic journal *Nature*, announced the 'Nature Index 2026' rankings on the 10th, local time. The Nature Index aggregates contributions of countries and institutions to high-quality research papers in major global journals and conferences, serving as a credible international benchmark for scientific research capabilities.
Leading the national rankings, China’s paper contribution score was 52,735, double that of the U.S. (26,006) in second place. While China’s score grew by 22.4% over the past year, the U.S. saw only a 4.2% increase. The institutional rankings further highlight China’s dominance: the Chinese Academy of Sciences ranked first, Zhejiang University second, and Harvard University third, dropping one spot from last year. Positions 4–10 were all Chinese institutions, with nine of the top 10 spots claimed by China. Europe’s Max Planck Institute fell outside the top 10 for the first time, while France’s National Centre for Scientific Research (CNRS) remained at 16th.
In the scientific community, U.S. pressure is seen as accelerating China’s research ecosystem self-reliance. Over recent years, the U.S. has restricted exports of advanced semiconductors, AI (artificial intelligence) accelerators, and quantum technology-related equipment to China. Chinese universities and institutions have responded by accelerating technology development with domestic resources. Some observers describe this as a paradoxical outcome where external pressure, like a ‘cornered rat,’ has strengthened cohesion among Chinese government, universities, and research bodies, expediting ecosystem growth.
The most symbolic change this year was Harvard University ceding the top spot to Zhejiang University, alma mater of DeepSeek founder Liang Wenfeng. Harvard, which had held the top position since the Nature Index began in 2015, dropped to second place for the first time. Zhejiang University’s paper contribution score grew by 22.7%, while Harvard’s increased by only 0.6%. Zhejiang’s rise is seen as a symbol of China’s science and technology ecosystem growth. Nine Chinese universities appeared in this year’s top 10 university rankings.
Conversely, U.S. university rankings declined due to legal battles between the Donald Trump administration and Harvard, as well as federal research funding cuts. The Massachusetts Institute of Technology (MIT) fell from 18th to 21st, and Stanford University dropped from 13th to 14th.
China’s university rise was not sudden. For years, it pursued a ‘talent black hole’ strategy, attracting global talent with special residency permits, lucrative salaries, ample research funding, and tenure-free professorships. This includes recruiting overseas scholars, such as Fields Medal winners, to Chinese institutions.
