China's rapid ascent in science has reached a historic milestone. According to a March 2026 report from the Organisation for Economic Co-operation and Development, the country's investment in research and development has now matched—and by purchasing power measures, exceeded—that of the United States. Both nations have crossed the $1 trillion threshold in research spending.
US Dominance Under Threat
For eight decades, the United States operated the most productive scientific and technological enterprise in human history. Breakthroughs from American labs include the internet, mRNA vaccines, transistors, semiconductors, the Global Positioning System, and countless other innovations. This leadership was nurtured by sustained public investment in research universities and federal laboratories, alongside a culture of open inquiry. These investments transformed scientific discovery into economic strength, accounting for more than 20% of all US productivity growth since World War II.
In stark contrast, China spent little to nothing on research and development in 1980, ranking among the lowest spenders worldwide. However, a systematic and relentless push has changed the landscape dramatically.
China's Systematic Rise
China's R&D spending milestone caps a series of rapid achievements. In 2019, China surpassed the US in its share of the top 1% most-cited papers—often referred to as the Nobel class of research. By 2022, it had taken first place globally in most-cited papers overall. In 2024, China overtook the United States in total scientific publications, marking the first time any nation has displaced American dominance since the US itself surpassed the United Kingdom in 1948. That same year, China pulled ahead in the Nature Index, which tracks publications in the world's most selective scientific journals, posting a 17% advantage over the US. Additionally, Chinese entities filed roughly 1.8 million patent applications in 2024, compared to the US's 603,191.
More Science Is Good, but the Problem Lies Elsewhere
China's ascent is, in one sense, good news. More knowledge generated by more researchers expands the global pool of discovery from which everyone can draw. The problem is not that China is investing, but that the US is not.
First, the US is divesting from basic, open science. Federal R&D spending peaked in 2010 at roughly $160 billion and fell by more than 15% over the following five years. Federal investment in research and development has been in a long, slow decline—from a peak of 1.86% of GDP in 1964 to about 0.66% in 2021. The federal government is no longer the largest spender in R&D; it funded about 40% of basic research in 2022, while the business sector performed roughly 78% of US R&D. Industry has simultaneously withdrawn from open scientific publication over the past four decades, shifting from research toward development. The result is a shrinking pool of openly shared scientific knowledge precisely as public investment contracts.
Under the second Trump administration, US government science agencies have been slow-walking proposals for new research. Current budget cuts from the White House threaten to deepen cuts to government spending significantly.
Second, there is active restriction of scientific exchange: tightening access to US institutions, scrutinizing international collaborations, and raising barriers to foreign-born researchers. These policies, though intended as security measures, work against the openness that has historically made American science productive and attractive to global talent. This issue exemplifies the stockyard paradox, in which securing research assets may weaken the very system these measures aim to protect.
Disinvestment Cuts Deeper Than It Appears
The deeper danger for the US economy is that disinvestment and selective engagement in research erodes the capacity to use cutting-edge science regardless of where it is produced. Absorbing and applying cutting-edge knowledge—whether developed in Boston or Beijing—requires maintaining research institutions and trained workforces, as well as active participation in global networks. This is not a passive process. A nation that hollows out its research base not only falls behind but also progressively loses its ability to benefit from science, including in technologies it can already access.
Talent compounds the problem. The US built its scientific dominance partly by being the destination of choice for the world's most ambitious researchers. The US leads the world in Nobel Prizes, but notably, 40% of the Nobel Prizes in chemistry, medicine, and physics awarded to Americans since 2000 were won by immigrants. The flow of foreign talent is not guaranteed; it follows opportunity, funding, and openness. Researchers who might once have come to American universities are finding welcoming alternatives in Europe, China, and elsewhere.
A Decision Point, Not a Trend Line
China's milestone in research funding arrives at a moment when the US is deciding whether to maintain its scientific leadership. Scientific infrastructure does not decline gradually and recover on demand. Doctoral scientists represent a decade or more of training; tacit laboratory knowledge lives in working research groups, not in documents. Once talented young researchers leave the pipeline—or international talent redirects to other countries—the capacity is very hard to rebuild. Early warning signs are already visible in the US system: thousands of NIH grants terminated, a collapse in international applications, and an exodus of early-career scientists.
What is at stake is not a ranking. It is whether the US maintains the institutional capacity—the universities, federal laboratories, graduate pipelines, and culture of open inquiry—that made those returns on scientific investment possible. China's rise did not create this decision point, although it brings it into sharp relief. The Information Technology and Innovation Foundation, a nonprofit think tank, estimates that a 20% cut in federal research and development starting in fiscal year 2026 would shrink the US economy by nearly $1 trillion over 10 years and reduce tax revenue by around $250 billion. Others point out that the scientific enterprise has contributed at least half of US economic growth. That is a lot to lose.
