当前全球商业航天发射领域正在发生深刻的成本重构。成本结构层面，传统火箭以一次性硬件制造为主 导，占比约67%，而新兴商业火箭通过可重复使用设计将硬件成本占比压缩至24%左右，形成"以复用 换成本"的可持续模式。其中火箭层面具体成本拆分，助推器占火箭总成本60%，二级占20%，整流罩 占10%，发射操作本身占10%。成本演化趋势来看，国内外商业航天企业正基于不同的发展路径推进成 本优化。以SpaceX为代表的企业通过十余年技术积累，已形成"复用程度提升—发射频次增长—单位成 本下降"的持续优化模式。与此同时，中国商业航天企业正加速实现技术突破与成本收敛，在自主型号 研发与规模化应用方面取得积极进展，呈现出系统化追赶态势。 全球发射放量直接兑现到发射服务商和整箭制造商，核心可复用部件与高频更换部件间接受益 发射服务商直接从单次发射费用和高频任务中获得现金收入，发射频次越高、单笔合同额越大，发射环 节利润弹性越显著。在发射需求释放背景下，发射服务与整箭交付作为直接面向客户的收费环节，收入 与发射任务数量或呈现对应关系，直接受益于发射放量大背景。此外，一子级和整流罩等高价值部件多 次周转使用，对发动机、主结构、控制系 ...

Investment Rating - The report provides a "Buy" rating for the industry, predicting that the stock price will outperform the Shanghai Composite Index by 15% or more within six months [56]. Core Insights - The global commercial space launch sector is undergoing a profound cost restructuring, shifting from a one-time manufacturing model to a reusable cost model. Traditional rockets have a hardware manufacturing cost share of about 67%, while emerging commercial rockets reduce this to around 24% through reusable designs [3][27]. - The launch market from 2024 to 2025 is expected to exhibit an absolute oligopoly, with launch service providers monopolizing orders and exerting control over the supply chain [5][42]. Summary by Sections 1. Cost Structure of Commercial Rockets - The cost breakdown of rockets shows that the first stage accounts for 60-70% of total costs, with engines being the most significant component, comprising over 50% of the first stage cost [13][27]. - The Falcon 9 rocket's cost structure indicates that the marginal cost of reuse is significantly lower than that of traditional rockets, with costs dropping to approximately $2,720 per kilogram in reusable mode [27][28]. 2. Industry Chain Benefits from Launch Volume - Launch service providers benefit directly from increased launch frequency and larger contracts, with revenue correlating to the number of launch tasks [4][35]. - The demand for reusable components and high-frequency replacement parts is expected to grow, driven by the need for higher reliability and maintenance of reusable systems [36]. 3. Investment Recommendations - Beneficiary stocks include companies involved in rocket manufacturing and space computing, such as Aerospace Power, Superjet, and West Materials, among others [6][52][53].
