Outline
This paper systematically analyzes the global development trend of low−cost and efficient space access capabilities and their profound impacts on the aerospace industry landscape, space security, and the future space economy, with a focus on the cost revolution driven by reusable launch vehicle technologies. By evaluating the technical paths, economic efficiency, and strategic deployment of leading international companies such as SpaceX, it identifies that the United States has established a generational advantage in this field, forming a virtuous cycle of "order−of−magnitude reduction in launch cost—enhanced market dominance—industrial chain restructuring." In contrast, China faces significant challenges in talent, technological reserves, and commercialization pathways, particularly in the areas of heavy−lift rockets and reusable technologies. The paper further assesses the current development status of China's commercial launch vehicles and concludes that although small− and medium−sized rockets are developing rapidly, they have yet to achieve breakthroughs in cost structure and technological models, making it difficult to support the high−frequency launch demands of satellite constellations and future space industries. Based on these findings, the paper proposes four policy recommendations: leveraging China’s unique national system, promoting coordinated innovation between state−owned and private enterprises, planning ahead for next−generation space transportation systems, and expanding international space information service exports. These aim to build a globally competitive space access capability framework.
