受影响个股
由传导链推断的相关标的、影响逻辑与近 30 日走势
美股
INTC
Intel
上游 · 中敏感5日 +12.7% 20日 -7.8%
英特尔作为美国本土芯片制造商,受益于《芯片法案》补贴及盟友产能回流需求,但其先进制程仍落后台积电,短期内难以完全替代亚洲产能,且中国市场萎缩将抵消部分本土增长
MU
Micron Technology
直接相关 · 高敏感5日 +6.6% 20日 -7.5%
项目直接执行方。$9.3B投资占Micron年营收约30%,是其史上最大单笔海外扩建,验证公司战略从周期性扩张转向地缘多元化。高敏感度因为:1)日本厂聚焦先进DRAM(1α/1β nm)与HBM,直接服务AI需求 2)2027年投产后日本产能占比将从5%提升至15%+ 3)日本政府补贴降低财务风险但长期盈利能力需验证
TSM
TSMC
直接相关 · 高敏感5日 +3.9% 20日 -3.9%
台积电是全球最大晶圆代工厂,美国施压其亚利桑那建厂已投入400亿美元,中国客户占营收约10%且面临出口管制,地缘分裂迫使其在美欧日多地重复建设产能导致成本结构恶化
日股
8035.T
Tokyo Electron
供应商 · 高敏感5日 -1.8% 20日 -21.6%
日本半导体设备龙头,直接受益于Micron本土采购。日本政府补贴可能附带本土设备采购比例要求(如30-40%),Tokyo Electron在刻蚀/涂胶显影等环节具备竞争力,可能获得$1.5-2B订单。高敏感度因为:1)Micron是Tokyo Electron重要客户 2)日本政府产业政策支持 3)DRAM设备需求周期性强,单笔大订单显著影响业绩
韩股
000660.KS
SK하이닉스
直接相关 · 高敏感5日 -17.2% 20日 -35.4%
SK海力士作为全球第二大存储芯片厂商,中国市场占营收约40%,中国AI芯片自给率提升将直接冲击其HBM等高端存储产品需求,且被迫在美建厂将大幅增加资本支出
005930.KS
삼성전자
直接相关 · 高敏感5日 -12.0% 20日 -22.0%
三星电子作为全球存储芯片和晶圆代工龙头,面临美国要求其在美本土建厂的直接压力,同时中国半导体自给率提升将侵蚀其在华市场份额,地缘分裂导致产能重置成本上升且客户流失风险加剧
