特朗普政府对中国半导体加征关税，税率竟然是0%！ 这听起来像是个笑话，但却是2025年12月23日美国贸易代表办公室白纸黑字发布的正式决定。他们还 给了中国18个月的"缓冲期"，要把真正的关税拖延到2027年6月才执行。 一场声势浩大的贸易战，愣是演成了姿态大于实质的政治表演。 就在美方宣布这一决定后不到24小时，中国外交部发言人林剑在12月24日的记者会上直接怼了回去："如果美方一意孤行，中方必将坚决采取相应措施，维 护自身正当权益。 "商务部的回应也紧随其后，批评美方单边关税违反世贸规则，损人不利己。 这种快如闪电的反击，让全球看到了中方的底气。 美方这番操作背后，其实是一笔政治经济账。 2026年美国就要迎来中期选举，此时若真对中国芯片加税，美国本土的汽车、家电、通信设备等行业成本会 立刻飙升，直接推高通胀。 当前美国通胀压力本就高企，特朗普政府根本不敢冒这个险。 更何况，美国制造业对中国成熟制程芯片的依赖程度超乎想象， 28纳米及以上芯片是许多美国关键基础设施的"刚需"，而中国在全球新增产能中占比接近一半。 美国贸易代表办公室的公告写得冠冕堂皇，声称中国芯片产业"不合理"地给美国商业带来负担，但翻遍文 ...

Core Viewpoint - The article discusses the ongoing technological and economic competition between the U.S. and China, particularly focusing on the semiconductor industry, highlighting how U.S. restrictions have inadvertently accelerated China's technological advancements [1][5][12]. Group 1: U.S.-China Semiconductor Competition - The technological rivalry between the U.S. and China began in 2018, centered around semiconductors, which are crucial for national security and various consumer technologies [3]. - U.S. actions, including export restrictions on semiconductor technology, are seen as counterproductive, potentially harming the U.S. semiconductor industry more than benefiting it [5][12]. - The U.S. restrictions have led to a significant increase in China's focus on self-reliance in semiconductor technology, with a reported self-sufficiency rate of nearly 70% in mature chips [10]. Group 2: Impact of U.S. Restrictions - Prominent figures like Bill Gates have warned that U.S. efforts to contain China could backfire, igniting innovation within China's semiconductor sector [5][8]. - Despite initial setbacks from U.S. restrictions, Chinese companies like Huawei have made significant strides in developing their own technologies, including the Kirin chip and Harmony OS [10]. - The market share of U.S. companies in China has declined, with Nvidia reportedly losing 10% of its market share and over $10 billion in revenue due to export restrictions [12]. Group 3: Future Outlook - The article suggests that the current challenges faced by Chinese tech companies will eventually lead to a brighter future, as they continue to innovate and reduce dependency on U.S. technology [12]. - China's advancements in AI and semiconductor technology are closing the gap with U.S. companies, indicating a shift in the global tech landscape [8].
