Progress, Hot Topics, and Development Trends in China's Low-Altitude Economy ResearchBased on Large Language Models and Visual Bibliometric Analysis

Driven by national policies, technological innovation, and expanding market prospects, China's low-altitude economy has entered a golden period of rapid development. There is an urgent need for scientific methods and tools to gain a comprehensive understanding of research and development in this field. In response, the study systematically examines the current status, hot topics, and cutting-edge trends in China's low-altitude economy based on Large Language Model (LLM) and visual bibliometric methods. The findings reveal an explosive growth in research after 2024, mainly concentrated in three thematic areas: concepts and characteristics, technologies and applications, and policies and development. Research hotspots include drones, general aviation, industrial chains, and application scenarios, while future research directions are likely to focus on digital and intelligent transformation, green development, security and privacy protection, international cooperation, and standardization. This study not only offers new ideas for conducting systematic and efficient literature reviews but also provides important references and insights into the research landscape and emerging trends in China's low-altitude economy.
