China’s Top-Journal Output Jumps 125% in Five Years
The number of papers published by Chinese scholars in the world’s three most prestigious academic journals — Cell, Nature and Science — surged 125 percent in 2025 compared with 2021, according to figures released by a senior science official. The data, presented on September 19 at the 6th New Cornerstone 50² Forum in Shenzhen, point to the rapid expansion of China’s research output and its growing weight in global science.
Dou Xiankang, a member of the Chinese Academy of Sciences and director of the National Natural Science Foundation of China (NSFC), said the growth in these “CNS” journals far outpaced that of comparable countries, including the United States and Germany. So far this year, Chinese scholars account for 45 percent of all CNS papers as first or co-first author, The Paper reported.
A Broader Rise in High-Quality Output
The CNS figures are one slice of a wider trend. Drawing on data from the Nature Index and the U.S. National Center for Science and Engineering Statistics (NCSES), The Paper found that China’s contribution to high-quality research, its share of highly cited work and its research spending have all climbed steadily, while the structure of its scientific collaboration has shifted.
According to the Nature Index’s 2026 release, which is based on roughly 125,000 original research papers published across 178 high-quality journals in 2025, China’s research contribution index reached 52,735.17 — about 42 percent of fractionalized contributions — up 22.4 percent year on year. The U.S. index stood at 26,006.15, up 4.2 percent.
China ranks first globally overall and in six fields or subfields: natural sciences, applied sciences, chemistry, biological sciences, physical sciences, and Earth and environmental sciences. Growth exceeded 20 percent year on year in applied sciences, natural sciences and health sciences, while chemistry, physics, biological sciences and Earth and environmental sciences all posted double-digit gains.
Yet the picture changes at the very top. In Nature and Science specifically, China’s contribution index was 295.16 against 938.09 for the United States — a gap that remains wide. The higher one climbs the research pyramid, the longer the catch-up takes.
Highly Cited Work: Closing the Gap Slowly
A longer view comes from highly cited papers — those in the top 1 percent of citations worldwide. According to an NCSES report published in May 2026, China’s share of top 1 percent highly cited science and engineering papers was 0.42 percent in 2006, versus 1.87 percent for the U.S. By 2022, China had risen to 1.29 percent while the U.S. slipped to 1.72 percent. Over 16 years, the gap narrowed to roughly 30 percent of its original size — a reduction of about 70 percent.
China crossed the 1 percent global benchmark in 2017 and has stayed above the world average since. But a telling time lag persists: China’s total output of science and engineering papers overtook the U.S. as early as 2017, yet by 2022 — the latest NCSES data — its share of top 1 percent cited papers had still not surpassed the American figure. In other words, parity in volume arrived far earlier than parity in influence.
Progress is also uneven across disciplines. In 2022, China’s share of top 1 percent cited papers exceeded the 1 percent global average in eight fields: materials, computer science, physics, health, biomedicine, chemistry, engineering and social sciences. In chemistry, China reached 1.47 percent, close to the U.S. figure of 1.50 percent.
Spending at Parity, Structure Still Diverging
Behind the rise in output lies decades of expanding research investment. On a purchasing-power-parity basis, China’s R&D spending was about $33 billion in 2000 — roughly one-eighth of the U.S. level. By 2024, China reached $1.028 trillion against $1.009 trillion for the U.S., putting the two essentially level.
Yet similar totals conceal very different structures. In 2024, basic research accounted for 6.88 percent of China’s total R&D spending, compared with about 14.6 percent for the U.S. The funding mix also differs: in the U.S., the federal government supplied 39.9 percent of basic research funding, businesses 34.3 percent and higher-education institutions 13.8 percent, making industry the second-largest source.
China’s basic research remains predominantly government-led. Luo Minmin, director of the Beijing Institute for Brain Science, told The Paper in a separate interview that 80 to 90 percent of his institute’s funding comes from government, with about 10 percent from enterprises and commissioned projects. Even so, he observed that companies are playing an increasingly prominent role, funding research with clearly defined questions in mind.
Collaboration Shifts
International collaboration tells a different story. In 2002, 13.3 percent of China’s science and engineering papers included international co-authors, versus 19.6 percent for the U.S. The two trajectories then diverged: China’s share peaked at 22.3 percent in 2018, while the U.S. climbed to 40.7 percent.
That decline does not mean fewer collaborative papers. The absolute number of China’s internationally co-authored papers is still rising — it is simply that total output grew faster, diluting the share. The result is two different growth structures: China’s overall output is expanding more rapidly, while a growing proportion of U.S. papers comes from international collaboration.
Talent and the Road Ahead
Dou also highlighted the human dimension of China’s research push. Speaking via China News Network, he noted that China overtook the U.S. in 2021 in the number of active researchers publishing in top journals, and now has seven times Japan’s total. Last year, the flow of students going abroad and returning reached a dynamic balance, he said.
The NSFC, which Dou heads, says nearly 90 percent of its projects are led by young researchers and 75 percent of its funds go to scientists under 45. Its Youth Science Fund added 3.6 billion yuan and 12,046 projects, a rise of more than 50 percent.
China’s ascent is rarely a matter of all indicators crossing the same line at once. The CNS surge and the Nature Index lead show a system scaling up fast; the persistent gaps in top-tier journals, basic research intensity and highly cited impact show where the harder climb lies. The coming years will test whether China can convert volume into influence — and whether its investment structure evolves to match its ambition.
