五分鐘學英文-美國關稅新戰場：台積電如何影響全球科技？

美國總統川普近期揚言對台積電等台灣半導體企業加徵關稅，這一政策可能對全球半導體供應鏈造成重大影響。台積電作為全球晶圓代工龍頭，其產品被廣泛應用於AI運算、智慧型手機、雲端運算等領域。若美國落實關稅政策，不僅台灣科技業將受到波及，美國本土的科技企業與全球供應鏈也將受到影響。
U.S. President Donald Trump has recently threatened to impose additional tariffs on Taiwan’s semiconductor companies, including TSMC. This policy could have a significant impact on the global semiconductor supply chain. As the world’s leading foundry, TSMC’s products are widely used in AI computing, smartphones, and cloud computing. If the U.S. implements tariff policies, not only will Taiwan’s tech industry be affected, but American technology firms and the global supply chain will also face disruptions.

美國對台積電的關稅政策，如何影響全球市場？How Will U.S. Tariffs on TSMC Affect the Global Market?

台積電的重要性與美國企業的依賴The Importance of TSMC and U.S. Companies’ Dependence

台積電（TSMC）是全球最大的晶圓代工廠，掌握約60%的市場份額，特別是在5奈米及以下的先進製程技術方面擁有無可取代的地位。許多美國科技巨頭依賴台積電，包括：
TSMC is the world’s largest semiconductor foundry, holding about 60% of the market share, particularly dominating 5nm and below advanced process technology. Many U.S. tech giants rely on TSMC, including:

• Apple（蘋果）——iPhone、Mac等設備的核心處理器（A系列、M系列晶片）。
  Apple – Core processors (A-series and M-series chips) for iPhone and Mac.
• NVIDIA（輝達）——AI加速晶片與GPU領域的關鍵供應商。
  NVIDIA – Key supplier of AI accelerator chips and GPUs.
• AMD（超微半導體）——x86處理器的主要競爭者。
  AMD – A major competitor in x86 processors.
• Qualcomm（高通）——全球手機晶片主要製造商之一。
  Qualcomm – A leading global supplier of mobile phone chips.

如果美國加徵關稅，這些企業的營運成本將上升，進一步影響消費電子產品、AI運算及伺服器市場。
If the U.S. imposes tariffs, these companies will face increased operational costs, which could affect consumer electronics, AI computing, and server markets.

高額關稅對美國市場的影響Impact of High Tariffs on the U.S. Market

根據分析，如果美國對台灣晶片徵收100%關稅，將帶來以下影響：
According to analysis, if the U.S. imposes 100% tariffs on Taiwanese chips, several major impacts may occur:

1. 晶片成本大幅上升——若關稅提高至100%，美國企業的晶片成本將增加59%，影響AI伺服器、智慧手機及高效能運算（HPC）等市場。
   Significant Increase in Chip Costs – Reports suggest that if tariffs rise to 100%, U.S. companies’ chip costs will increase by 59%, affecting AI servers, smartphones, and high-performance computing (HPC).
2. 美國企業競爭力受損——蘋果、NVIDIA、AMD等企業的產品成本提高，可能導致終端產品（如iPhone、MacBook、AI伺服器）售價上升，進而影響全球銷售。
   Weakened Competitiveness of U.S. Tech Firms – Companies like Apple, NVIDIA, and AMD may have to raise product prices (iPhone, MacBook, AI servers), reducing global demand.
3. 科技股市場震盪——半導體產業是美股的重要支撐，若關稅政策落地，可能造成美股短期大幅震盪。
   Stock Market Volatility – The semiconductor industry is a crucial pillar of the U.S. stock market. If tariffs are imposed, it may cause significant short-term market fluctuations.

目前，美國本土半導體產能無法取代台積電。Intel的代工業務尚未成熟，製程技術落後台積電至少2至3個世代，而台積電與三星在美國的新工廠短期內無法滿足市場需求。
Currently, U.S. domestic semiconductor production cannot replace TSMC. Intel’s foundry business remains underdeveloped and lags TSMC by 2-3 generations, while new plants by TSMC and Samsung in the U.S. will take time to ramp up production.

供應鏈重組的趨勢，哪些企業將受影響？Supply Chain Restructuring: Which Companies Will Be Affected?

台灣科技企業的應對策略Taiwan’s Tech Industry Response

面對潛在的關稅衝擊，台灣半導體與電子業者開始積極調整供應鏈：
In response to potential tariff impacts, Taiwan’s semiconductor and electronics industry has started actively restructuring its supply chain:

台積電加速海外擴張TSMC Accelerates Overseas Expansion

• 美國亞利桑那州晶圓廠（2024年開始投產，主要生產4奈米和3奈米製程）。
  Arizona Fab in the U.S. (Set to start production in 2024, focusing on 4nm and 3nm processes).
• 德國、日本的投資計劃，減少對單一市場的依賴。
  Investment plans in Germany and Japan to reduce reliance on a single market.
• 增加美國本地生產以規避關稅，降低風險。
  Increasing local production in the U.S. to avoid tariffs and mitigate risks.

聯發科（MediaTek）等公司啟動風險評估MediaTek and Other Companies Assessing Risks

聯發科正在進行內部供應鏈模擬測試，評估美國關稅影響，並考慮轉向台積電美國工廠生產部分晶片，以確保產品成本維持競爭力。
MediaTek is conducting internal supply chain simulations to assess the impact of U.S. tariffs and is considering shifting part of its production to TSMC’s U.S. fab to maintain cost competitiveness.

其他台灣科技公司重新配置供應鏈Other Taiwanese Tech Companies Restructuring Their Supply Chain

• 鴻海（Foxconn）、和碩（Pegatron）等組裝廠加快印度與越南的投資，以分散風險，減少對中國與美國市場的依賴。
  Foxconn, Pegatron, and other assembly manufacturers are accelerating investments in India and Vietnam to diversify risks and reduce dependence on the Chinese and U.S. markets.

美國科技業的挑戰 Challenges for the U.S. Tech Industry

美國企業若要擺脫對台積電的依賴，可能會面臨以下問題：
If U.S. companies want to reduce their reliance on TSMC, they may face the following challenges:

1. 美國本土晶片製造能力不足：目前美國的代工能力仍以Intel和GlobalFoundries為主，但其技術落後於台積電至少2至3個世代，短期內無法完全替代。
   Insufficient Domestic Semiconductor Manufacturing Capacity: Currently, the U.S. relies on Intel and GlobalFoundries for foundry services, but their technology lags behind TSMC by at least 2 to 3 generations, making it impossible to fully replace TSMC in the short term.
2. 美國半導體製造成本過高：台積電雖在亞利桑那州設廠，但因美國的勞工與基礎建設成本較高，晶片成本可能上升30%以上，這將進一步推高美國企業的成本。
   High Semiconductor Manufacturing Costs in the U.S.: Although TSMC has established a fab in Arizona, the high labor and infrastructure costs in the U.S. may increase chip production costs by more than 30%, further raising expenses for U.S. companies.
