前言 2026年1月，高市早苗等来中方一套雷霆组合拳。 中方不仅在两天内切断了军事两用物项的出口，更直接对日本芯片关键原料启动了反倾销调查，精准击中了产业命门！ 日本政府一边高调抗议声称绝不接受反制，一边却目睹着市场恐慌迅速蔓延…… 连发两道公告 48小时，两道金牌，就在韩国总统李在明带着合作清单满意而归、享受着"好酒"待遇的同时，日本却收到了迎接"豺狼"的猎枪。 1月6日，中国商务部发布2026年1号公告，全面加强对日两用物项出口管制。 有意思的是，日本政府嘴上硬得很，实际上已经开始慌了神，日本经产省紧急召开会议研讨对策，企业界更是风声鹤唳。 高市早苗政府试图摆出一副强硬姿态，但在中方"依法依规、正当合理"的回应面前，这种抗议显得苍白无力。 外交部发言人一针见血地指出，日方干涉内政甚至发出武力威胁在先，中方的反制不过是维护自身权益的必要之举，这就好比别人先拔刀，你不许人家还 手，这种强盗逻辑在今天早已行不通。 不到两天，7号又发布2号公告，直接对原产于日本的二氯二氢硅发起反倾销立案调查。 这种节奏感极强的连续出招，完全打破了日本"政冷经热"的旧有幻想，东京的反应完全在意料之中，又是抗议，又是嚷着"违背国际惯 ...

Core Viewpoint - The article discusses the impact of U.S. export controls on semiconductor technology, particularly focusing on NVIDIA's adjustments to its supply chain and the implications for Chinese tech companies [2][3]. Group 1: NVIDIA's Supply Chain Adjustments - NVIDIA has informed three Chinese tech companies about its supply chain adjustments in response to U.S. government export control policies [2]. - The adjustments are linked to the U.S. restrictions initiated in October 2022, specifically targeting high-performance computing chips for AI training [2]. - NVIDIA previously created "downgraded" versions of its chips, A800 and H800, for the Chinese market, but these are now also restricted under new regulations [2]. Group 2: Impact on Chinese Tech Companies - The three companies likely include major Chinese server manufacturers and AI firms, such as Inspur and Huawei, which heavily rely on NVIDIA GPUs for AI model training and data center construction [3]. - These companies may face short-term challenges, including power shortages and delays in research and development [3]. - Some firms are testing domestic chips like Huawei's Ascend and Cambricon, but compatibility and performance issues remain significant hurdles [3]. Group 3: Long-term Implications for the Semiconductor Industry - U.S. technology controls may accelerate the domestic replacement of AI chips in China, with products like Huawei's Ascend 910B achieving 80% of the performance of international mainstream chips [3]. - The software ecosystem for these domestic chips still requires improvement, and some companies are exploring RISC-V architecture or distributed computing solutions to reduce dependency on foreign technology [3]. - The U.S. policies are leading to a bifurcation in the global semiconductor supply chain, creating different technical standards for Chinese and non-Chinese markets [3].
