5月3日消息，自中国宣布对7类稀土相关物项实施出口管制后，欧洲镝价已上涨两倍，达到每公斤850美元（约6180.6元人民币），铽价则从每公斤965美 元上涨至3000美元。原本稀土就是战略物资，以后白菜价格真不能再卖了，因为卖一点少一点，几十年后稀土稀缺了甚至用完了，千金难买就欲哭无泪 了。稀土价格虽然翻倍上涨，但依然没有达到它的应有价位，在现有价格上涨五十倍甚至一百倍才是它的应有价值。希望国家加强管控，特别是打击走 私，还稀土的本来面目。 想想以前的碳纤维等，只要我们造不出的国外就是天价卖给你。而我们稀有的东西，由于内卷却变成白菜价，国家真的需要更加觉醒。反正和美国已经脱 钩了，涨个100倍干它千万不要客气，在对方替代之前狠狠涨，对美国限量供应。据说稀土开采、提炼都是毁坏环境高污染的行业，美帝、西方国家一是 不愿干这脏活，二来人家环境保护比较严格，所以这个行业也只有发展中国家全产业链来干了，正因为如此中国的稀土产业链比较完整齐全技术有优势成 本低！ 提炼稀土需要大量电力，有些是铝土矿伴生，也就是冶炼几百吨铝才出几十克稀土，美国不可能为了一点稀土大干电解铝，有了铝美国又没能力消化怎么 弄？所以说目前提炼技术精 ...

资料图 用于高性能磁体的镝和铽的价格在一个月内涨至3倍，均创出历史最高价。中国4月初对7类中重稀土启 动了出口限制措施。一方面，美国已与乌克兰签署资源开发协议，计划展开包括稀土在内的资源开 发…… 中国政府于4月4日宣布，对铽、镝等7种稀土实施出口管制。Argus Media分析："预计这些稀土在管制 发布后几乎立即停止出口"。 稀土即使少量添加，也有望显著提升材料性能，因此广泛用于纯电动汽车和风力发电的电机、航空航天 等高端制造领域，被形容为"工业的维生素"。稀土分为轻稀土和中重稀土，此次被管制的7种属于产量 稀少的中重稀土。这类稀土的开采高度依赖中国，中国在该领域拥有压倒性的存在感。 日本瑞穗银行产业调查部高级分析师佐藤多嘉大指出："这次被限制的稀土，在其他国家实施替代性生 产的难度非常高"。中重稀土价格暴涨直接导致用于纯电动汽车等产品的电机成本上升。东京大学的冈 部彻教授说："若供应受限长期化，电动汽车本身可能面临无法制造的风险"，类似这样的担忧也在浮 现。 版权声明：日本经济新闻社版权所有，未经授权不得转载或部分复制，违者必究。 日经中文网 https://cn.nikkei.com 对于纯电动汽车（ ...

Group 1 - China's announcement on April 4 to impose export controls on seven categories of medium and heavy rare earth elements has led to record-high prices for rare earth metals within weeks [1][3] - As of May 1, the price of dysprosium in Europe has doubled since early April, reaching $850 per kilogram (approximately 6180.6 RMB), while the price of terbium surged from $965 per kilogram (approximately 7016.9 RMB) to $3000 per kilogram (approximately 21814.1 RMB) [1][3] - The price increases for rare earth metals are the largest monthly gains and highest prices recorded since May 2015 [1][3] Group 2 - Over 90% of refined rare earth elements globally come from China, highlighting the country's dominance in this sector [3] - The export controls are viewed as a response to the Trump administration's imposition of "reciprocal tariffs" on China [3] - Rare earth metals are critical for manufacturing advanced products such as electric vehicles, wind turbine motors, and aircraft, with the restricted elements classified as rarer medium and heavy rare earths [3] - Analysts indicate that it is challenging to substitute the restricted rare earth materials with those produced in other countries, which could impact the cost of electric motors used in electric vehicles and other products [3]

Core Viewpoint - The European Court of Auditors (ECA) report indicates that China has become the largest source of mature chip imports for the EU, with the EU's dependency on China reaching a "high-risk" level due to U.S. semiconductor technology export controls [1] Group 1: Market Dependency and Goals - The EU aims to capture 20% of the global chip market by 2030, but currently, it is far from this target [1] - Approximately one-third of the EU's mature chip imports come from China, highlighting the significant reliance on Chinese sources [3] Group 2: Industry Competitiveness - Despite having competitive companies like Infineon in Germany, NXP in the Netherlands, and STMicroelectronics, these firms primarily serve the automotive sector and cannot meet the growing demand within the EU [2][3] - The ECA's 2024 survey reveals a semiconductor trade deficit of €9.8 billion between the EU and China, which may widen as the demand for mature chips, crucial for green and energy-efficient technologies, continues to rise [3]

更关键的是控制系统。稀土基传感器能够以毫秒级的响应速度捕捉运动部件的空间位置、速度及加速度变化，并将这些数据实时反馈给中央处理器。正是这 种近乎完美的闭环控制，才赋予了"擎天柱"类人般的协调性和稳定性。 今年4月4日，中国商务部的一纸公告在全球市场掀起轩然大波。对钐、钆、铽等7类中重稀土的出口管制措施，不仅是一纸行政命令，更是一份战略宣言。 官方明确表示，这是为了"维护国家安全和利益，履行防扩散等国际义务"，但背后的战略考量显然更为深远。 中国在全球稀土供应链中的地位堪称"定海神针"。数据显示，中国稀土储量占全球三分之一以上，却供应着全球90%以上的市场需求。这种不对称的供需关 系，使得中国的每一个政策调整都会在国际市场引发连锁反应。 值得注意的是，这次管制并非无差别打击。中国采取了精准的"外科手术式"管控，重点针对可能用于军事用途的中重稀土。韩国媒体曝光的商务部信函显 示，中方特别要求韩企不得将含中国稀土的产品转售美国军工企业。这种有的放矢的做法，既维护了正常的国际贸易秩序，又有效防范了战略资源的外流风 险。 据央视新闻报道，特斯拉CEO埃隆·马斯克公开表示，中国对稀土的出口管制已经严重影响了人形机器人"擎 ...

4月30日，三星电子发布了2025年第一季度财报，报告显示，该公司DS部门（半导体事业部）一季度营 业利润环比下降62.1%至1.1万亿韩元（约合人民币56.0亿元），营收25.1万亿韩元（约合人民币1277.6 亿元），环比下降17%，但同比上升9%。 三星在财报中指出，由于平均销售价格的下降，以及部分由于人工智能芯片的出口管制导致的高带宽芯 片（HBM）销量下降，其整体盈利能力受到冲击。 据《日经亚洲》报道，三星电子表示，美国对华先进芯片出口管制正在损害其在中国的业务。 三星位于西安的NAND闪存制造子公司——三星中国半导体有限公司去年的销售额为11.2万亿韩元（约 合人民币570.1亿元），而一年前为8.7万亿韩元（约合人民币442.8亿元）；三星的销售子公司上海三星 半导体2024年的销售额为30.1万亿韩元（约合人民币1532.1亿元），比前一年的15.6万亿韩元（约合人 民币794.0亿元）增长了近一倍。 此前拜登政府针对中国芯片产业发布了三轮出口管制规则，涉及从禁止销售特定类型半导体到限制芯片 制造设备出口等多项措施。 不过，三星的设备体验部门（包括视觉显示、家电、智能手机等业务）表现良好，一季 ...

国芯网[原:中国半导体论坛] 振兴国产半导体产业！ 不拘中国、 放眼世界 ！ 关注 世界半导体论坛 ↓ ↓ ↓ 4月30日消息，三星发布Q1财报， 由于 美国出口管制导致高端芯片销量下滑，三星半导体利润暴跌42%！ 财报显示，三星电子Q1营收为79.1万亿韩元，同比增长10%，分析师预测为78.1万亿韩元，刷新了单季销 售额记录；营业利润为6.7万亿韩元，同比增长1.5%，分析师预测为6.4万亿韩元；净利润同比增长22%， 为8.2万亿韩元。 分部门业务来看，负责芯片业务的设备解决方案（DS）部门，Q1销售额为25.1万亿韩元，营业利润为1.1 万亿韩元，同比下降42%。 三星电子称，芯片部门营业利润下降主要因为平均售价下降，并且美国出口管制导致高带宽存储芯片 （HBM）销量下滑；同时，一些客户推迟了订单，以等待即将推出的增强型HBM3E产品。 三星电子表示，"由于最近全球贸易环境恶化和宏观经济的不确定性增加，例如经济增长放缓，很难预测 未来的表现"，并补充说，"我们计划继续采取各种措施来确保增长。 三星内存计划通过满足对 HBM3E 12 层改进产品的初始需求，并运营以服务器大容量产品为中心的业务， 加强其 ...

来源：内容编译自路透社 ，谢谢。 三位知情人士称，特朗普政府正在研究修改拜登时代的一项规则，该规则将限制全球获取人工智能 芯片的权限，包括可能取消将世界划分为多个层级以确定一个国家可以获得多少先进半导体的规 定。 消息人士称，该计划仍在讨论中，并警告称可能会有所调整。但如果该计划得以实施，取消这些分 级制度可能会为美国芯片在贸易谈判中成为更强有力的谈判工具打开大门。 该法规于今年 1 月发布，旨在划分最先进人工智能芯片的使用权，并控制某些模型权重，以便将 最先进的计算能力保留在美国及其盟友手中，远离令人担忧的国家。 这项名为《人工智能扩散框架》的规定由美国商务部于今年1月发布，当时距离前总统乔·拜登执政 结束还有一周。自5月15日起，企业必须遵守该框架的限制规定。 目前，该规则将世界划分为三个等级。第一等级的17个国家及台湾可以获得无限量的芯片。其他 约120个国家/地区属于第二等级，这意味着它们获得的人工智能芯片数量受到限制。而第三等级的 包括俄罗斯、伊朗和朝鲜等值得关注的国家/地区则被禁止获得芯片。 但消息人士称，特朗普政府官员正在考虑放弃该规则中的分级准入方式，代之以政府间协议的全球 许可制度。 几个月 ...
