當世界越不安全，國家就越願意花錢買安全。

根據斯德哥爾摩國際和平研究所最新報告，2025年全球軍事支出已達約2.89兆美元，創下歷史新高，並連續第11年成長。

這筆龐大開支相當於全球GDP的2.5%，也是自2009年以來最高水準，顯示全球安全環境正快速惡化。

從區域來看，「歐洲」成為推升軍費的最大動力之一。在俄烏戰爭持續影響下，歐洲軍費大幅成長約14%；同時亞洲與大洋洲也增加超過8%，反映區域緊張情勢升溫。

值得注意的是，美國軍費反而出現7.5%下降，主因是對烏克蘭軍援暫停，但整體全球支出仍持續上升，顯示軍備競賽已不再由單一國家主導。

目前全球前三大軍費支出國——美國、中國與俄羅斯——合計占全球支出的51%，仍是影響軍事格局的核心力量。

專家指出，全球軍費上升背後的關鍵原因，是多重危機同時發生：包括俄烏戰爭、中東衝突，以及印太地區緊張局勢，使各國加速「再武裝化」。

這意味著，世界正在進入一個長期的「高軍費時代」。

三個觀察重點

1️⃣ 全球進入長期軍備競賽，台灣無法置身事外
軍費連續11年上升，代表安全環境已結構性惡化，台灣必須持續強化防衛能力。

2️⃣ 歐洲經驗顯示「威脅出現＝軍費暴增」
俄烏戰爭讓歐洲迅速擴軍，對台灣而言，台海風險同樣可能帶來類似壓力。

3️⃣ 不只是武器，而是整體國力競爭
軍費背後包含產業、科技與供應鏈，台灣應結合半導體與AI優勢，打造國防韌性。

Global Military Spending Hits Record High: A World Investing More in War Than Ever

As global insecurity rises, nations are spending more than ever on defense.

According to the Stockholm International Peace Research Institute, global military expenditure reached approximately $2.89 trillion in 2025, marking a record high and the 11th consecutive year of growth. 

This accounts for 2.5% of global GDP, the highest level since 2009, reflecting a rapidly deteriorating global security environment. 

Europe has been a key driver of this surge, with spending rising by around 14%, largely due to the ongoing Russia-Ukraine war. Meanwhile, Asia and Oceania increased spending by over 8%, highlighting growing regional tensions. 

Interestingly, U.S. military spending declined by 7.5%, mainly due to a pause in aid to Ukraine. However, global spending still increased, indicating that the arms race is no longer driven by a single country. 

The top three spenders—the United States, China, and Russia—account for 51% of global military expenditure, continuing to dominate the global defense landscape. 

Experts point to multiple overlapping crises—Ukraine, the Middle East, and Indo-Pacific tensions—as key drivers behind the surge, signaling a broader global rearmament trend. 

The world is entering a prolonged era of high military spending.

Key Takeaways

1️⃣ A long-term global arms race is underway
Rising military budgets reflect structural changes in global security.

2️⃣ Threat perception directly drives spending
Europe’s surge shows how quickly defense budgets can rise under pressure.

3️⃣ Beyond weapons: competition of national strength
Military spending increasingly includes technology, industry, and supply chains.
