For the first time since 2015, Harvard University has lost its position as the world’s leading research university according to the Nature Index, ceding the top spot to a Chinese competitor.
For the first time in more than a decade, in the 2026 Nature Index research leaders ranking, Harvard is no longer the world’s top higher education institution in terms of high‑quality research output. The first place is now held by Zhejiang University in Hangzhou, China.When research institutes, government agencies, and medical institutions are included, Harvard ranks only third, behind the Chinese Academy of Sciences (CAS) and Zhejiang University.
Harvard’s research growth has stagnated. According to Nature Index, the latest data show that the gap between China’s leading research institutions and the rest of the world is widening.The CAS share index (a measure of a country’s, organization’s, or institute’s contribution to scientific articles published in journals tracked by Nature Index) reached more than 3,655 points in 2025—nearly three times that of Zhejiang University.
Meanwhile, Harvard’s research output grew by only 0.6% year‑on‑year, far below the overall expansion rate of the Nature Index database.This year’s ranking confirms the dominance of Chinese institutions: nine of the world’s top ten universities are Chinese. In addition to Zhejiang University, others such as Sichuan University, Fudan University, and Shanghai Jiao Tong University have made significant progress.
Sichuan University entered the top 10, while Shanghai Jiao Tong University recorded the strongest rise between 2024 and 2025. Conversely, many renowned Western research institutions continued to fall. Germany’s Max Planck Society dropped out of the top 10 for the first time, and France’s CNRS now ranks 16th.Top U.S. universities have not been spared. Stanford University fell to 14th place, while MIT dropped three places to 21st.
The Nature Index notes that this shift is more than just rankings—it reflects the rapid development of China’s research ecosystem in fields with global scientific impact. Chinese institutions now occupy all top ten positions in applied sciences and chemistry, and nine of the top ten in earth and environmental sciences.In health sciences, traditionally a U.S. stronghold, Chinese institutions are also expanding. Apart from Harvard, the National Institutes of Health and Stanford remain among the few American institutions still in the top 10.
East Asia’s growth Not only China but also other East Asian countries are showing increasing competitiveness against Western research powers.According to Nature Index, China’s research contribution is expected to rise by 22% between 2024 and 2025, far surpassing that of the top ten countries. Japan and South Korea also recorded increases of nearly 10%, higher than those of the U.S., the U.K., and Germany.
Although insufficient to catch up with China, these gains demonstrate East Asia’s strong adaptation to the new research environment. Interdisciplinary projects, computing technologies, and efforts to address social challenges are becoming increasingly central.In Japan, positive signs are emerging after years of perceived stagnation. According to Motoko Kotani, adviser at Tohoku University, policymakers shifted their approach about a decade ago—from research serving the scientific community to research serving society.
This led to reforms such as greater university autonomy, concentrated investment in strategic research infrastructure, and stronger support for young researchers. In 2023, the Japanese government created a ¥10 trillion (about US$63 billion) fund to secure long‑term resources for academic research.The ASPIRE program was also launched to promote international cooperation in strategic fields such as AI, biotechnology, and semiconductors. However, internationalization remains a major challenge, as Japan still struggles to attract global talent and expand cross‑border collaboration.
Meanwhile, South Korea benefits from a tightly integrated model linking research and industry. The country devotes nearly 5% of its GDP to R&D—one of the highest rates in the OECD—with more than 80% of research spending coming from businesses.The South Korean government currently prioritizes fields seen as drivers of major breakthroughs, including AI, quantum technologies, robotics, and semiconductors. This approach allows rapid transformation of research results into commercial products, generating resources for new research activities.
Experts believe this is a major advantage for South Korea in a global scientific landscape increasingly focused on technological innovation and industrial capacity. However, the country remains less prominent in fundamental research, where China, the U.S., Japan, and Europe continue to dominate.
