德国约6000亿欧元（约6870亿美元）的国防支出计划构成自冷战以来最大规模军事转型，并作为经济刺激源扩散。该支出不受严格财政规则约束，规模可能超过5000亿欧元的基础设施计划。政策推动下，国防订单向本土集中，约85%合同留在国内或欧洲区域，显著改变此前对外采购预期，并通过信贷扩张与快速审批机制加速资金流动。

宏观与行业指标显示明显增长效应。瑞银估计国防将在2028年前贡献约0.5个百分点GDP增长；制造业订单在11月至次年1月间增长7.4%。企业层面，Hensoldt订单增长62%，Rheinmetall自2025年初股价上涨超过160%，并在仅15个月内建成新弹药工厂，显示产能扩张速度显著提升。新创企业亦快速进入市场，例如成立于2023年的公司完成3000万欧元融资并扩大多国生产布局。

结构性变化体现在产业链重构与资本配置转向。汽车等传统制造业向军工供应链转移，银行体系（如专门融资团队）提高资金可得性。需求端受多重冲突驱动，包括中东局势带来的短期订单增加。尽管存在产能瓶颈与外部竞争风险，当前趋势显示从“政策意图”向“执行规模化”的转变，形成持续的订单、投资与技术扩散循环。

Germany’s €600 billion ($687 billion) defense program marks its largest military transformation since the Cold War and acts as a macroeconomic stimulus. The spending is exempt from strict fiscal limits and may exceed the €500 billion infrastructure plan. Policy shifts concentrate procurement domestically, with about 85% of contracts allocated within Germany or Europe, reversing prior expectations of foreign sourcing and accelerating capital deployment through credit expansion and faster approvals.

Macro and sector data indicate measurable growth effects. UBS estimates defense will add about 0.5 percentage points to GDP by 2028, while manufacturing orders rose 7.4% between November and January. At the firm level, Hensoldt orders increased 62%, Rheinmetall shares surged over 160% since early 2025, and it built a new ammunition plant in just 15 months, highlighting rapid capacity scaling. Startups are expanding quickly, including a 2023-founded company securing €30 million and scaling production across multiple countries.

Structural shifts are visible in supply chains and capital allocation. Traditional sectors such as automotive are pivoting into defense supply, while banks increase financing access via dedicated teams. Demand is reinforced by multiple conflicts, including short-term boosts from Middle East tensions. Despite risks of capacity constraints and external competition, the trajectory shows a transition from “policy intent” to “scaled execution,” creating a reinforcing cycle of orders, investment, and technological spillovers.
