特朗普關稅如何衝擊Nvidia中國業務與股價

美國新一輪關稅重擊Nvidia中國業務

美國拜登政府最近宣布,將針對中國的半導體、電動車、電池和其他高科技產品加徵新一輪關稅。這一舉動不單止針對中國的產業,更直接衝擊到美國科技巨頭Nvidia(輝達)——作為全球AI晶片龍頭,Nvidia一直高度依賴中國市場。新一輪關稅政策令Nvidia在中國的業務面臨前所未有的挑戰,也引發了其股價的劇烈波動。

中國市場為Nvidia帶來什麼?

對於Nvidia來說,中國市場舉足輕重。根據過去數年財報顯示,中國市場佔Nvidia總收入約20%至25%,主要來自數據中心和AI晶片的銷售。中國科技公司,包括阿里巴巴、百度、騰訊等,都是Nvidia的主要客戶,廣泛應用其A100、H100等高階AI加速卡,推動雲計算、人工智能、機器學習等領域發展。

美國限制措施如何發酵?

自2022年起,美國政府已經陸續加強對中國出口高階半導體的限制。今年新一輪關稅,令Nvidia向中國出口部分AI晶片的門檻更高,不但要面對更複雜的審批流程,還可能因為成本上升而失去價格競爭力。Nvidia雖然嘗試為中國市場設計「閹割版」AI晶片,但美國商務部的審查亦越來越嚴格,令這些「特供版」產品的市場空間進一步收縮。

股價反應與投資者憂慮

消息一出,Nvidia的股價即時受壓。投資者擔心,若中國市場進一步受限,Nvidia的收入增長會大打折扣。雖然公司管理層強調,AI需求在全球範圍內依然強勁,但現實是,中國市場的空缺未必能即時由其他地區補上。此外,中國企業亦加快自研AI晶片,減少對Nvidia的依賴,這對Nvidia的長遠競爭力構成威脅。

中美科技戰升級,Nvidia何去何從?

Nvidia的困局,正正反映中美科技戰的升級。美國希望透過技術封鎖,限制中國在AI和高端運算領域的發展;中國則加快本土創新,推動半導體國產化。Nvidia夾在兩國之間,一方面要遵守美國政府的出口管制,另一方面又不想失去中國這個龐大市場。未來,Nvidia可能要進一步調整其全球業務策略,包括加強對印度、東南亞、中東等新興市場的開拓,減低對中國的依賴。

編輯評論:Nvidia的「兩難困局」與全球科技新格局

這次Nvidia被關稅「夾擊」,凸顯了全球科技產業鏈的高度政治化。以往,科技巨頭只需要專注技術創新與市場拓展,現在卻要面對地緣政治的博弈。Nvidia的處境不是個別現象,而是整個美國科技業的縮影。

值得關注的是,中國未來未必只是「失去」Nvidia,更可能迫使中國企業加速自立自強,最終培養出本土AI晶片巨頭,對Nvidia構成長遠競爭。對香港和亞洲其他地區來說,這場科技戰既是風險也是機遇——香港作為國際金融與科技樞紐,能否吸納受影響的企業資源,成為新一輪科技產業轉移的受益者?

最後,這場關稅戰不單是商業競爭,更是全球科技格局重塑的前奏。Nvidia如何突圍,將成為全球投資者和行業觀察者的重要參考指標。對於香港的科技企業和投資者,這個案例提醒我們,單靠某一市場、某一技術路線的風險愈來愈大,多元化與靈活應變將是未來的生存之道。
