國產 AI 晶片產能缺口達四成把簡體中文原文的重點轉成繁體中文讀者更容易閱讀的脈絡。核心在於 China’s AI-chip bottleneck is shifting from design to wafer capacity on SMIC’s N+2 line.
變化在哪裡
目前可核驗的事實包括：Huawei taking about 43% of 2026 N+2 allocation, around 15,000 wafers per month under a five-year agreement, Cambricon at roughly 9% to 11%, estimated annual capacity around 2.6 million domestic AI chips, demand around 4.2 million, and a gap near 1.6 million chips。這些細節讓新聞不只停留在發布會口號。
為什麼重要
A design win is not enough if only one advanced domestic line can manufacture enough usable chips. AI 新聞已經不能只看模型分數，還要看成本、供應、監管與真實工作流程。
接下來看什麼
Allocation rules, yield, packaging choices and new capacity will decide which chip vendors can actually ship. 下一步要看的不是更多宣傳，而是第三方測試、客戶續用與長時間穩定性。
