🧠 行业洞察
✅ 机遇关注
长鑫科技今日科创板上市,Q1营收508亿同比+719%,H1净利预计500-570亿,国产DRAM龙头对接资本市场后产能扩张和技术升级有望加速,利好上游设备和封测产业链
下周微软/Meta/AMD/亚马逊/高通密集发布Q2财报,云厂商Capex指引是判断下半年AI基础设施需求的关键信号,若资本支出持续上调利好服务器和光通信产业链
⚠️ 风险提示
FCC新规从整机禁售升级为零部件级封堵,华为/中兴含逻辑处理功能的组件全面禁入美国市场,短期合规成本增加,中长期加速中美ICT供应链分离,需关注欧盟是否会跟进类似措施
🏆 竞品动态
FCC禁止含华为/中兴零部件设备在美销售FCC从整机禁售升级为零部件级封堵,华为/中兴相关通信模块在美国市场的间接出口渠道被彻底切断。但华为/中兴在美份额已近零,短期直接冲击有限。需关注欧盟是否会跟进类似措施,以及第三方设备商(TP-Link等)被迫切换供应链带来的竞争格局变化,可能为其他交换机厂商创造短期订单转移窗口。
长鑫科技科创板上市,国产DRAM龙头获资本市场支持中国最大DRAM厂商上市后产能扩张和技术升级有望加速,上游设备、封测等国产化产业链受益。但长鑫上市对服务器/存储市场竞争格局的直接影响有限,短期内不改变全球DRAM三巨头(三星/SK海力士/美光)主导格局。

FCC Votes to Ban US Sales of Devices Containing Huawei/ZTE Components — Escalates from Whole-Device to Chip-Level Restrictions [详见中文版] — On July 22, the US Federal Communications Commission (FCC) voted to approve a new rule banning the sale of devices in the US that contain 'logic-bearing hardware components' manufactured by Huawei, ZTE, and other Chinese firms designated as national security risks. FCC Chairman Brendan Carr stated the rule aims to 'fully close the component loophole,' extending previous restrictions from whole-device bans to component-level restrictions. The rule covers any device containing chips, communication modules, or baseband processors from designated Chinese firms. (AP News / US News & World Report)
China Retaliates Against EU Sanctions: 14 EU Entities Added to Export Control List — Third Use of Export Control Law in Three Months [详见中文版] — On July 25, China's Ministry of Commerce (MOFCOM) announced the addition of 14 EU entities — including Lafarge Group and others — to its export control list, prohibiting the export of dual-use items to these entities. The action is a direct retaliation against the EU's 21st round of Russia-related sanctions (July 23), which listed 14 Chinese mainland and Hong Kong enterprises. This marks China's third use of its export control law within three months, following April (7 entities over Taiwan) and May (first use of the Anti-Foreign Improper Extraterritorial Jurisdiction Regulation against EU FSR investigations).
