    Abstract
  • The NSFC-Civil Aviation Joint Research Fund serves national strategic needs, focuses on fundamental research for civil aviation applications, promotes scientific and technological innovation, and supports industry development through its research outcomes. To systematically understand the topic evolution of the NSFC-Civil Aviation Joint Research Fund projects, a text mining method combining word frequency analysis and latent Dirichlet allocation (LDA) topic modeling is applied to analyze the topic selection guidelines and project approvals from 2004 to 2023. The study reveals the keyword characteristics of the guidelines, analyzes research hotspots and their evolutionary trends, and provides the research prospects of civil aviation. The results indicate that: ①The NSFC-Civil Aviation Joint Research Fund exhibits distinct phases and attracts diversified research forces. ②The guidelines are highly consistent with national policies and strategic development directions. Keywords such as civil aviation, airport, aircraft, safety, emergencies, and NextGen have frequently appeared in the guidelines over the past 20 years, while low-altitude operation may emerge as a new hotspot in future. ③The fund mainly focuses on 11 research topics, including aircraft airworthiness, airport construction and operation, air traffic management and optimization, aviation safety and risk management, emergencies and emergency management, green aviation, and so on. ④Four topics including aircraft airworthiness, airport construction and operation, air traffic management and optimization, and aviation safety and risk management have remained hot in the past 20 years. The research hotspots in civil aviation are shifting from traditional infrastructure construction and safety technology fields to emerging fields such as informatization, intelligence, and green development. The trend is also moving from single-discipline dominance to multidisciplinary integration. Looking ahead, the future NSFC-Civil Aviation Joint Research Fund is expected to focus on constructing a digital intelligence ecology, enhancing system-wide safety, and promoting green development. By fostering multifaceted synergistic cross-fertilization and developimg an autonomous knowledge system, it aims to drive the high-quality development of civil aviation.
