摘要
[目的/意义]全面梳理全球商业航天产业研究现状与趋势,揭示全球商业航天专利技术演变情况,为国内商业航天产业研究与发展提供参考。[方法/过程]基于6493篇Web of Science文献数据和8663件专利数据,运用文献计量分析方法、专利指标法及S曲线法,探讨了全球商业航天研究领域文献发表数量的年度分布、国家分布、机构分布、研究热点及前沿领域等情况,分析了领域内专利技术的生命周期变化情况。[结果/结论]2000年以来,全球商业航天年发文量呈显著上升趋势,美国在商业航天文献发表和合作网络方面领先,中国虽发表量居次,但国际合作有待加强。卫星、近地轨道及远程遥感等关键词成为新的研究热点,深度学习等新兴技术与商业航天正在加速融合。根据专利指标与S曲线分析预测结果,未来5~10年是商业航天高速发展从成长期进入成熟期的关键时期,应把握机遇布局商业卫星和商业火箭专利技术领域,积极拓展通信、导航、遥感应用新场景和开拓卫星应用大众服务领域,加速商业航天领域进入产业化阶段。
[Objective/Significance]To comprehensively review the research status and trend of global commercial space industry,reveal the evolution of global commercial space patent technology,and provide reference for the research and development of domestic commercial space industry.[Method/Process]Based on the data of 6493 Web of Science articles and 8663 patents,this paper used the bibliometric analysis method,patent index method and S-curve method to discuss the annual distribution,country distribution,institution distribution,research hotspots and frontier fields of the global commercial space research.The life cycle changes of patent technology in the field are analyzed.[Results/Conclusions]Since 2000,the annual number of global commercial space publications has shown a significant upward trend.The United States leads in commercial space literature publication and cooperation network,while China ranks second in publication volume,but international cooperation needs to be strengthened.Keywords such as satellites,low-Earth orbit and remote sensing have become new research hotspots,and emerging technologies such as deep learning are merging with commercial space at an accelerating pace.The analysis of patent indicators and S-curve predicts that the next 5-10 years will be a critical period for the rapid development of commercial space from the growth period to the maturity period.We should seize the opportunity to lay out the patent technology fields of commercial satellites and commercial rockets,actively expand new scenarios for the application of communications,navigation,remote sensing,and explore the public service fields of satellite applications,and accelerate the industrialization of commercial space.
