商业航天行业研究系列2：SpaceX，可重复使用运载火箭发射霸主冲向火星

Investment Rating - The report suggests a positive investment outlook for the commercial aerospace industry, particularly focusing on the opportunities presented by SpaceX's monopolistic position in launch services and the monetization path of the Starlink satellite constellation [2]. Core Insights - The core investment logic for the commercial aerospace sector in A-shares is to embrace the explosive growth period of satellite constellation infrastructure and to identify high-barrier component suppliers. China is currently in a phase similar to SpaceX's network-building period from 2018 to 2020. As the G60 and GW networks enter a dense launch phase, satellite manufacturing is transitioning from custom lab designs to mass production akin to automotive assembly lines. The most certain alpha returns in the industry will come from high-value, high-barrier core satellite components and payloads [2]. Summary by Sections 1. SpaceX Overview - SpaceX is not a traditional aerospace manufacturer but a monopolist in space logistics and infrastructure, applying first principles to disrupt conventional beliefs about rocket costs and single-use designs. It has created a self-reinforcing business loop by leveraging the unmatched launch cost advantages of Falcon 9 to build the largest space communications network, Starlink, and using the cash flow generated to fund ambitious projects like Starship [4]. 2. Competitive Advantages - Cost Barriers: SpaceX's reusability model has drastically reduced launch costs, with marginal costs dropping to nearly $15 million per launch, achieving gross margins of around 68% after five reuse cycles. This cost structure provides SpaceX with pricing power against traditional aerospace giants [4]. - Manufacturing Barriers: Over 80% of SpaceX's components are self-developed, allowing for rapid iteration and cost control through vertical integration. This strategy has transformed rocket manufacturing from a craft-based approach to an industrialized process [4]. - Customer Barriers: SpaceX has established a strategic symbiosis with the U.S. government, which has become a significant source of funding for its core R&D through long-term contracts, ensuring a reliable and cost-effective access to space [4]. 3. Growth Curves - SpaceX's value proposition should not be compared to traditional defense contractors but viewed as a combination of three distinct business life cycles: 1. The launch business as a cash cow with high market share and profitability. 2. The exponential growth of Starlink, transitioning from B2B to B2C services, characterized by recurring revenue similar to SaaS models. 3. The disruptive potential of Starship, which could unlock trillion-dollar markets in space tourism, intercontinental transport, and deep-space resource extraction [4]. 4. Financial Trajectory - SpaceX has seen its valuation soar from approximately $27 million at inception to nearly $200 billion, reflecting a growth of nearly 7400 times over two decades. The financing history shows a clear evolution from focusing on cheaper rockets to expanding into satellite internet and ambitious space exploration projects [29][30]. 5. Product Ecosystem - SpaceX's business model is built on a self-reinforcing loop, utilizing its launch market dominance to deploy Starlink satellites at internal marginal costs, thereby increasing competitive pressure on rivals. The combination of stable cash flow from launch services and the growing SaaS revenue from Starlink supports the overarching goal of funding Starship development [31][32].
