美國限售晶片,港股科技股暴跌!




美國限制英偉達向中國銷售晶片,港上市科技股下跌

路透社報道,美國政府限制英偉達(Nvidia)向中國銷售H20人工智慧晶片,擔心這些晶片可能被用於超級電腦。英偉達是目前向中國銷售最先進晶片的供應商,這些晶片對於英偉達參與中國蓬勃發展的人工智慧產業至關重要。

中國科技巨頭的股價因此下跌,阿里巴巴(Alibaba)港股下跌4.8%至104.6港元,創下自4月7日以來最大單日跌幅。騰訊(Tencent)下跌2.9%至442.6港元。電動汽車製造商小鵬汽車(Xpeng)港股下跌6.8%,比亞迪(BYD Co)下跌3.7%,蔚來汽車(NIO)下跌4.7%。

此外,送餐服務提供商美團(Meituan)下跌7.6%,電子商務集團京東(JD.com)下跌4.7%,電腦製造商聯想(Lenovo)下跌4.4%,手機製造商小米(Xiaomi)下跌4.1%。

不過,中國晶片製造商的股價卻上漲,華虹半導體(Hua Hong)上漲3.9%,中芯國際(SMIC)微升0.1%。

恒生科技指數下跌3.6%,恒生指數下跌1.9%。

作為編輯,我認為美國限制英偉達向中國銷售晶片的舉動,對中國科技產業的發展可能產生深遠影響。英偉達的晶片對於中國的人工智慧產業至關重要,中國科技巨頭紛紛搶購這些晶片,以滿足對低成本AI模型的需求。美國的限制可能會迫使中國科技公司尋找替代供應商,或自行開發晶片,這可能會增加中國科技產業的自主創新能力。

然而,這也可能對中國科技產業的短期發展產生負面影響,特別是對於那些依賴英偉達晶片的公司。中國政府可能需要採取措施支持國內晶片產業的發展,以減輕美國限制的影響。

此外,這也反映出美國和中國之間的科技競爭日益激烈,雙方都在爭奪人工智慧等戰略性產業的主導權。未來,中國科技產業可能會面臨更多的挑戰和機遇,如何應對這些挑戰,將是中國科技公司和政府需要思考的問題。
