In recent years, the focus of U.S.-China technological competition has shifted from simple technology blockades and countermeasures toward deeper institutional rivalry and ecosystem building. Initially, the U.S. sought to slow China’s technological rise through entity lists and export controls restricting access to advanced semiconductors and critical technologies. However, as China intensifies its domestic investments in semiconductors, artificial intelligence, and renewable energy—and as global supply chains continue to reconfigure—the underlying logic of this rivalry is undergoing a fundamental transformation.On one hand, the U.S. now recognizes that unilateral sanctions alone cannot fully contain China’s innovation capacity. It has pivoted toward a “small yard, high fence” strategy—erecting high barriers around core technologies while rallying allies to form exclusive tech alliances. On the other hand, China is accelerating its push for technological self-reliance, strengthening basic research, talent development, and industrial chain coordination to build a secure and controllable innovation ecosystem. This shift—from “strangling chokepoints” to “building ecosystems”—signals an escalation from tactical skirmishes to strategic competition.Moreover, Global South nations are playing an increasingly pivotal role in shaping the future of technology. Both the U.S. and China are vying for influence over technical standards and narratives around development models. Going forward, this tech rivalry will be less about raw hardware dominance and more about institutional appeal, openness to collaboration, and sustainable innovation capacity.
近年来，中美科技博弈的焦点已从单纯的技术封锁与反制，逐步转向更深层次的制度竞争与生态构建。早期，美国通过实体清单、出口管制等手段限制中国获取高端芯片与关键技术，试图延缓中国科技崛起。然而，随着中国在半导体、人工智能、新能源等领域的自主投入加大，以及全球供应链格局的重塑，博弈逻辑正在发生根本性转变。一方面，美国意识到单边制裁难以彻底遏制中国创新能力，转而推动“小院高墙”策略，即在关键核心技术领域构筑高壁垒，同时联合盟友构建排他性技术联盟。另一方面，中国则加速推进科技自立自强，强化基础研究、人才培养和产业链协同，力图打造安全可控的创新生态。这种从“卡脖子”到“筑生态”的转变，标志着双方竞争已从战术层面升级为战略层面。此外，全球南方国家在科技发展中的角色日益重要，中美都在争取技术标准制定权与发展模式话语权。未来，科技博弈将不仅是硬实力的较量，更是制度吸引力、开放合作能力与可持续创新能力的综合比拼。
