In recent years, global university research rankings have shown a notable trend of ‘China rising, the U.S. declining.’ According to authoritative rankings such as the Nature Index, QS World University Rankings, and Times Higher Education (THE), Chinese universities have consistently improved in research output volume, international collaboration, and highly cited papers, while some U.S. institutions have seen slower relative growth. Several factors drive this shift: first, the Chinese government has significantly increased investment in higher education and basic research, advancing its ‘Double First-Class’ initiative to elevate institutional research capabilities; second, China’s rapidly growing pool of researchers and upgraded research infrastructure provide a solid foundation for high-quality outputs; third, amid intensifying U.S.-China tech competition, China has prioritized indigenous innovation and accelerated the translation of research into practical applications. Although the U.S. still maintains world-leading strength in cutting-edge and disruptive research, it faces challenges including slower growth in research funding, political uncertainties, and reduced appeal to international talent. It’s important to note that the ‘rise of China, decline of the U.S.’ primarily reflects differences in scale and growth rate—America retains an edge in originality and breakthrough science. Going forward, the global research landscape is likely to become more multipolar, with Chinese and American universities jointly shaping a new ecosystem of scientific innovation through both collaboration and competition.
近年来，全球高校科研成果排名呈现出‘中升美降’的显著趋势。根据多个权威排名（如自然指数、QS世界大学排名、THE泰晤士高等教育等）数据显示，中国高校在科研产出数量、国际合作、高被引论文等方面持续提升，而美国部分高校则在相对增速上有所放缓。这一变化背后有多重原因：首先，中国政府持续加大对高等教育和基础研究的投入，推动‘双一流’建设，激励高校提升科研水平；其次，中国科研人员数量快速增长，科研基础设施不断完善，为高质量成果产出奠定基础；再者，中美科技竞争背景下，中国更加注重自主创新，加速科研成果转化。相比之下，美国虽仍保持顶尖科研实力，但受制于科研经费增长放缓、政治环境波动及国际人才吸引力减弱等因素，整体科研扩张速度不及中国。值得注意的是，‘中升美降’更多体现在科研体量与增速层面，美国在原创性、颠覆性科研方面仍具领先优势。未来，全球科研格局或将更趋多极化，中美高校将在合作与竞争中共同塑造科技创新的新生态。
