空间应用指利用空间资源、空间资产及空间特殊条件，在地面或空间进行直接和间接的技术利用、产品生产、服务供给的总称；经过60多年的发展建设，我国航天事业成就突出，在轨卫星资源超过400颗，但与空间应用密切相关的体系设计、基础数据库和标准建设等方面还不能满足高质量发展的需要。本文面向航天强国建设和航天系统中长期发展需求，在研判国内外发展环境和形势的基础上，总结了我国空间应用产业与技术发展的新态势和新需求，梳理了空间应用领域发展面临的挑战；提出了面向航天强国建设的空间应用发展总体思路、建设目标、顶层体系，论证形成了空间应用发展的重点方向。研究建议，完善政策法规，推动法治航天建设；转变发展理念，推进天、地、用一体化；优化体制机制，大幅提升服务水平，推进形成天、地、用互促发展，标准统一，协调健康的空间应用新格局。

Space application refers to the direct and indirect technology utilization, product production, and service provision on the ground or in space by utilizing space resources, assets, and conditions. After over 60 years of development, the aerospace industry of China has made significant achievements, with over 400 satellites in orbit. However, the system design, basic database, and standards construction that are closely related to space application still cannot satisfy the requirements of high-quality development. Considering the demand for strengthening China's aerospace industry and the medium- and long-term development requirements of the industry, this study reviews the development status of space application in China and abroad, summarizes the new requirements for space application industry and technologies in China, and analyzes the challenges faced by space application. Moreover, the general ideas, development goals, and top-level systems of space application for strengthening China's aerospace industry are proposed. The key directions for the development of space application are explored. Furthermore, we suggest that China should improve policies and regulations associated with the aerospace industry, promote the integration of space, ground, and users, and optimize mechanisms and services of the industry, so as to promote the formation of a coordinated space application pattern that features space-ground-user interactive development and unified standards.
