Advanced logic manufacturing is concentrated in Taiwan to a degree with no parallel, and that concentration is a present structural exposure rather than a scenario. What a Taiwan-specific interruption would do is not documented and is graded as an unconfirmed scenario throughout.
為地緣政治風險與經濟曝險工作撰寫：它追溯的是一項機制，而非市場觀點。
如何解讀等級
- 已證實 有來源記錄其已經發生。
- 合理可信的曝險 Vigil評估為很可能的機制；尚無其已經發生的紀錄。
- 未經證實的情境 因為值得觀察而列出。並非斷言。
一個步驟的等級永遠不能高於它所依賴的步驟：結果的確立程度不能高於其原因。這項規則在本網站建置時強制執行，而非以人工套用 — 違反它的鏈會導致建置失敗，而不會被發布。
- 觸發因素
先進半導體製造目前集中於單一地域，以及這種集中所造成的依賴
- 受影響的資產、路線或地區已證實
臺灣西部平原上的一個產業聚落，生產了世界上絕大多數最先進的邏輯晶片。此一集中是有文件記載的當前事實，但確切的地理占比並非公開數字：可以陳述的是，台積電在2026年第2季的純晶圓代工市場營收中約占73%，而7奈米及以下製程在2026年第1季約占其自身晶圓營收的74%——分別是一家公司在某一市場區隔中的占比，以及一家公司營收中的占比，兩者都無法換算為按地點計算的全球產能占比。此一集中與第二項事實並存：該聚落依賴進口的特殊材料、進口能源、持續的高品質電力，以及暢通的空運與海運。美國、日本與歐洲正在興建產能——台積電的亞利桑那計畫為265十億美元、涵蓋六座邏輯晶圓廠，其中一座自2024年底起已進行N4量產，下一座目標於2027年下半年進行N3量產——同時臺灣本地的先進產能也在平行擴張。多元化是真實的，以年計，但不等於集中程度下降。
有來源記錄其已經發生。
- 營運中斷已證實
此產業聚落已因與海峽無關的原因承受過壓力，而這些事件就是可用的證據。2021年的嚴重乾旱限制了晶圓製造的供水，需要以卡車運水並優先配水。自2022年起的出口管制重組了該產業的貿易地理，使該聚落同時成為數個首都的政策議題。兩者皆非安全事件，但都顯示了此系統對晶片以外的投入有多敏感。
有來源記錄其已經發生。
- 曝險的產業或商品已證實
暴露於風險的各方是與此爭端毫無關聯的產業。汽車、消費電子、工業設備、醫療器材與國防製造業都會因缺少一個零件而停擺，無論該零件價格多少，正是這一機制使半導體供應的傳播速度超過其貿易占比所顯示的程度。2020–2023年的全球短缺——起因於疫情帶來的需求轉移，而非海峽中的任何事情——是這種傳播如何運作的實證紀錄，而它在數月內就波及其他大陸的汽車生產線。
有來源記錄其已經發生。
- 更廣泛的經濟意義未經證實的情境
臺灣特有的供應中斷會造成什麼後果，並無文獻記載，Vigil也不作此斷言。以下列為值得觀察的事項，而非斷言：2020–2023年的短缺源於在供應持續下的需求變化，而來源端的供應中斷將是不同的機制，目前沒有已發表的分析確立兩者如何比較。可作出的觀察範圍較窄，也較為確定 — 多元化在落後製程節點上降低曝險的速度快於先進節點；依賴產業的庫存緩衝以週而非季計；受影響的各方將包括在此政治問題上沒有立場的國家。Vigil不發布任何關於規模、持續時間或成本的估計，此一缺席是刻意的。
因為值得觀察而列出。並非斷言。
曝險的產業與商品
以一般標籤命名，而非受控詞彙，因此這份清單不會與本模組經濟部分已使用的商品名稱產生偏差。
仍然未知的事項
- No defensible public figure was found for the share of world sub-7nm capacity physically located on Taiwan. Company market share and company revenue mix are published and are different measures; this chain states them as such and does not convert them into a geographic share.
- No published analysis establishes how a source interruption would compare to the demand-driven 2020–2023 shortage, which is why the final step is graded as an unconfirmed scenario.
- Site-level capacity, yields, customer allocation and inventory positions are commercially confidential and are not published.
- Estimates of the timeline for meaningful leading-edge diversification vary widely between published assessments and are contested.
- Vigil publishes no magnitude, duration or cost estimate for any interruption scenario, and the absence is deliberate rather than a gap awaiting research.
證據同樣支持的其他解讀
- Diversification investment can be read as reducing global exposure to Taiwan, or as reducing everyone else's dependence while leaving Taiwan's own vulnerability unchanged and diminishing whatever deterrent value the concentration carries. Both are argued seriously and they imply opposite conclusions about whether diversification improves stability.
- The 2020–2023 shortage can be read as evidence of how badly an interruption would propagate, or as a poor analogue because its cause was demand rather than supply. This chain records it as the available evidence while grading the inference from it as unconfirmed.
列出這些解讀，是因為該紀錄本身的評估並非其來源所允許的唯一評估 — 而不是對上述評估的保留。
在臺灣以外實際「投產」的先進製程產能有多少？
Announced, under construction and in volume production are three different figures separated by years, and only the third changes the concentration this chain describes. The checkable milestones are TSMC Arizona fab two on N3, targeted for volume production in the second half of 2027, and fab three on N2 and A16 by the end of the decade — against continued expansion of advanced capacity on Taiwan itself, which is the comparison that matters.
依賴型產業的庫存做法
Buffers grew after the 2020–2023 shortage and have since been trimmed. The trend is the clearest measure of how exposed customers actually are.
任何司法管轄區的出口管制變化
They reorganise the trade geography faster than any factory can be built, and they now originate in several capitals.
對產業聚落的水電分配
The 2021 drought showed these are live constraints in ordinary years.
