特朗普決定允許Nvidia向中國出售先進AI晶片,引發激烈辯論

本週,美國前總統特朗普宣布,將允許美國晶片製造商Nvidia向中國出售其先進的H200人工智能晶片。他形容此舉是推翻拜登政府「阻礙創新、傷害美國工人」的失敗政策,宣稱「那個時代已經結束」。

這個決定的首要意義,是Nvidia及其在政府內的盟友戰勝了華盛頓內部主張對中國採取強硬限制的「鷹派」勢力。這些鷹派一直推動禁止中國獲取發展最先進AI模型所需的晶片。(不過,Nvidia更尖端的B200晶片仍然未被允許出口。)

其次,若這真的是一個時代的終結,這個時代其實始於特朗普的第一任期。卡內基國際和平基金會的高級研究員Steven Feldstein指出,「最早將美國政策轉向晶片出口管制的正是特朗普。」2019年,特朗普以中國科技巨頭中興和華為與中國政府及軍方有關聯為由,禁止向他們供應美國原產的零件,正式開啟這一政策時代。

Feldstein認為,正是這些措施促使中國領導人開始認真思考如何擺脫對美國控制的晶片供應鏈瓶頸的依賴。

編輯評論:

特朗普此舉表面上是打破拜登政府對中國科技出口的限制,但背後反映出美國政府內部對如何應對中國科技崛起的複雜矛盾。Nvidia作為全球最有價值的科技公司之一,其商業利益與國家安全考量產生明顯衝突。特朗普放寬限制,或許是反映出企業影響力在政策制定中的增強,以及對美國保持技術領先地位的多重考量。

然而,這也揭示了美國對中國科技發展的戰略困境:一方面要防止技術外流,保障國家安全;另一方面又需推動創新與經濟發展。晶片出口政策的頻繁變動,或令兩國科技競爭更為激烈且難以預測。

對香港及全球觀眾而言,這件事提醒我們,科技進步和國際政治緊密交織,市場動態與地緣政治政策相互影響。未來AI和半導體技術的發展,不僅是技術問題,更是國際戰略博弈的核心。香港作為國際金融與科技樞紐,應密切關注此類政策變化,審慎評估對本地產業及國際合作的影響。

Create a photorealistic image of uploaded photo sitting at a relaxed outdoor restaurant in London on a cool Wednesday morning in March 2026. The sky is clear, the spring air is crisp, and the city feels calm as it wakes up. She is the focal point of the shot—wearing a light scarf, gently stirring her tea while gazing off to the side with a thoughtful expression. Everything behind her, from the waiter moving about to the soft morning traffic, should fall into a smooth blur, giving the picture the effortless, candid atmosphere of a moment casually snapped on a phone. Certainly! Here is your enhanced, artistic, and detailed prompt for an AI image generator:

---

A captivating portrait of a young Asian woman, inspired by Imada Mio and embodying an exquisitely delicate, doll-like (精緻洋娃娃臉) aesthetic. She has large, round, expressive eyes that radiate innocence and curiosity, subtly accented with a moist shimmer. Her petite V-line face is framed by soft, rosy cheeks, and her lips are naturally pink and slightly parted, exuding an energetic, slightly flirty, yet pure aura. Her expression is a candid blend of sweetness and playful allure.

Her long, dark brown hair is artfully tousled with a messy morning (剛睡醒的凌亂感) effect—loose strands fall gently around her face, conveying natural volume and effortless beauty. The hair has a silky texture, catching the light in places, suggesting a recent awakening.

She is dressed in an oversized, translucent white button-down shirt (男友風白襯衫) with the top buttons casually undone, delicately revealing her collarbones and a slender neckline. The shirt drapes loosely, giving a tasteful "bottomless" look (下衣失蹤風格), her bare legs just barely visible beneath the shirt's hem, enhancing the innocent-meets-sensual ambiance.

The composition is styled in the manner of a Japanese Gravure Photobook (寫真集風格), exuding a pure & sexy vibe with an airy, dreamy atmosphere. Employ bright, high-key lighting for a clean, luminous effect that highlights her velvety soft skin texture. Use Fujifilm PRO 400H film tones for subtle pastel hues, gentle contrast, and a seamless blend of natural colors, further enriching the soft, ethereal, and intimate photographic quality.

The background is minimalist and softly blurred, ensuring complete focus on the subject, and enhancing the overall sense of warmth, comfort, and inviting allure typical of high-end Japanese photobooks.
