The global science and technology system is currently undergoing profound transformations, marked by three major trends. First, technological competition has become the core of strategic rivalry among major powers. Frontier fields such as artificial intelligence, quantum computing, semiconductors, and biotechnology have emerged as key battlegrounds where the United States, China, the European Union, and other major economies vie for technological supremacy. Second, the landscape of international scientific collaboration is rapidly reconfiguring. Heightened geopolitical tensions and rising techno-nationalism are challenging traditional open innovation models, giving rise to regionalized and bloc-based tech alliances—examples include the Chip 4 Alliance and technology cooperation frameworks under the Indo-Pacific Economic Framework. Third, global tech governance norms are evolving swiftly. Countries are placing increasing emphasis on data security, algorithmic ethics, and AI regulation, actively shaping standards and rules aligned with their national interests. As a result, the global tech governance system is shifting from unipolar dominance toward a more pluralistic, multilateral model. These three shifts are not only reshaping the global innovation ecosystem but also imposing new demands on national science policies, industrial strategies, and international cooperation.
当前，国际科技体系正经历深刻变革，主要呈现三大趋势。第一，科技竞争日益成为大国战略博弈的核心。以人工智能、量子计算、半导体和生物技术为代表的前沿领域，已成为美国、中国、欧盟等主要经济体争夺技术主导权的关键战场。第二，全球科技合作格局加速重构。受地缘政治紧张、技术民族主义抬头等因素影响，传统的开放式创新模式受到挑战，区域化、阵营化的科技联盟正在形成，如‘芯片四方联盟’（Chip 4）和‘印太经济框架’下的技术合作机制。第三，科技治理规则加快演进。各国对数据安全、算法伦理、人工智能监管等问题日益重视，推动建立符合本国利益的科技标准与规范，全球科技治理体系正从单极主导向多元共治转变。这三大变化不仅重塑全球创新生态，也对各国科技政策、产业布局和国际合作提出新要求。
