本研究以Starlink为例提出预估巨型星座互联网服务需求的方法，发现其用户集中于富裕国家，需求增长慢于轨道容量及非Starlink互联网整体需求，或意味着该市场盈利性低于预期。

商业太空经济的近期增长与近地轨道（LEO）环境的可持续性，取决于大型LEO卫星电信星座（即“巨型星座”）的商业前景。若成功，巨型星座可推动发射服务商间的竞争，或降低发射价格；它们还可能需要轨道可持续性服务，或产生额外碰撞风险，进而影响太空可持续性利益。消费者对巨型星座互联网服务的需求是其商业成功的关键。本分析以SpaceX的Starlink在2021年12月至2023年11月的数据为例，提出一种预估消费者对巨型星座互联网服务需求的方法。该分析发现，Starlink用户高度集中在最富裕国家；还发现，消费者对Starlink的需求增长速度慢于轨道容量的新增速度，也慢于非Starlink互联网的整体需求增长速度。这些趋势的持续或表明，巨型星座互联网市场的盈利性低于此前预测的水平。
英文摘要
The near-term growth of the commercial space economy and sustainability of the low-Earth orbit (LEO) environment depends on the commercial prospects of large LEO satellite telecommunications constellations (``mega-constellations''). If successful, mega-constellations can spur competition between launch providers, which may lead to lower launch prices. They may also demand orbital sustainability services and/or generate additional collision risk, which may in turn affect space sustainability interests. Consumer demand for mega-constellations' internet services is critical to their commercial success. This analysis presents a method to estimate consumer demand for mega-constellations' internet services, using SpaceX's Starlink over December 2021--November 2023 as an example. This analysis finds that Starlink users are highly concentrated in the wealthiest countries. It also finds that consumer demand for Starlink is growing more slowly than orbital capacity is being added and more slowly than demand for non-Starlink internet overall. Continuation of these trends may indicate that the market for mega-constellation internet is less lucrative than previous forecasts have indicated.
