我国航天事业因历史原因和投入限制，在初期以空间技术、空间应用为主，对空间科学重视不足，空间科学、空间技术、空间应用基本上是独立发展的；着眼新时期航天强国建设，需要将空间技术的发展深度融合到空间科学、空间应用中去，从而创造新的机遇和成就。本文剖析了空间科学、空间技术、空间应用的基本内涵并明确三者的相互关系，在系统分析国际空间科学、空间技术、空间应用的整体态势，细致梳理我国相关领域发展情况的基础上，论证了统筹我国空间科学、空间技术、空间应用协调发展的必要性，凝练了三者协调发展面临的主要问题。空间科学、空间技术、空间应用之间既有需求交叉，又可互促带动，应在规划、部署、实施的全过程中进行统筹考虑：发挥新型举国体制优势，在统一管理下做好顶层规划；坚持创新驱动发展战略，以技术进步抢占国际航天制高点；支持空间领域基础研究，培育高水平的科学家和工程师队伍；加强资源统筹协调，促进空间应用数据的合理开放和充分利用。

Owing to historical reasons and investment restrictions, China's aerospace industry initially focused on space technology and application, with insufficient emphasis on space science; therefore, space science, technology, and application developed independently. The development of space technology should be deeply integrated into space science and application, thus to strengthen China's aerospace industry and create new opportunities and achievements. This study explores the implications of space science, space technology, and space application and clarifies their interrelationships. Moreover, it systematically analyzes the development trend in space science, technology, and application worldwide and reviews the development situation of space-related fields in China. Based on this, it examines the necessity for coordinating the development of space science, technology, and application in China and summarizes the major challenges. Considering their overlapping needs and mutual promotion, space science, technology, and application should be coordinated throughout the process of planning, deployment, and implementation. First, the advantages of the new national system should be exploited to conduct top-level planning under unified management. Second, the innovation-driven development strategy should be insisted to promote the international competitiveness of China's aerospace industry through technological progress. Third, basic research in the space field should be strengthened and high-level scientists and engineers should be cultivated. Lastly, resource planning and coordination should be strengthened to promote the rational opening and full utilization of space application data.
