2024年5月，美国政府宣布对特定半导体产品加征25%的关税，作为其加强本土高科技产业竞争力和国家安全战略的一部分。此次加税主要针对从中国进口的先进计算芯片、存储芯片及相关制造设备，旨在限制中国获取尖端半导体技术的能力，并推动美国本土半导体制造业回流。该举措是拜登政府延续《芯片与科学法案》政策方向的重要步骤，通过财政补贴与贸易壁垒双管齐下，强化美国在全球半导体供应链中的主导地位。然而，这一关税措施也引发了业界担忧：一方面可能推高美国科技企业的生产成本，影响消费电子、人工智能和数据中心等关键领域；另一方面，或进一步加剧中美在科技领域的脱钩趋势，扰乱全球供应链稳定。分析人士指出，尽管短期内美国希望借此保护本国产业，但长期来看，若缺乏国际合作与市场开放，反而可能削弱全球半导体生态系统的效率与创新活力。
In May 2024, the U.S. government announced a 25% tariff on specific semiconductor products as part of its broader strategy to bolster domestic high-tech competitiveness and national security. The new tariffs primarily target advanced computing chips, memory chips, and related manufacturing equipment imported from China, aiming to restrict China’s access to cutting-edge semiconductor technologies and incentivize the reshoring of semiconductor manufacturing to the United States. This move aligns with the Biden administration’s continuation of policies under the CHIPS and Science Act, combining financial subsidies with trade barriers to reinforce U.S. leadership in the global semiconductor supply chain. However, the measure has raised concerns within the industry: it may increase production costs for U.S. tech firms and negatively impact critical sectors such as consumer electronics, artificial intelligence, and data centers. Moreover, it could accelerate technological decoupling between the U.S. and China, further destabilizing global supply chains. Analysts note that while the U.S. seeks short-term protection for its domestic industry, a long-term lack of international collaboration and market openness might ultimately undermine the efficiency and innovation capacity of the global semiconductor ecosystem.
