Abstract:	This research employs the nearest-neighbour index, kernel density estimation, Global Moran's I, and the Geographically and Temporally Weighted Regression (GTWR) model to analyse the spatial characteristics of general aviation tourism products in the Middle Yangtze River Economic Region. The results indicate that (1) the development of aviation tourism products has become increasingly uneven over time; (2) the spatial distribution exhibits a dual-core radiation pattern, with the primary core located in Wuhan, Xiaogan, and Ezhou (Hubei Province), and a secondary core in Jingmen, Yichang, and Jingzhou (Hubei Province); (3) high-high (H-H) and low-high (L-H) clusters are predominantly concentrated in Hubei Province, whereas low-low (L-L) clusters are mainly distributed in Hunan Province, indicating provincial disparities ranked as Hubei > Jiangxi > Hunan. Overall, significant spatiotemporal disparities are observed across the region. Key influencing factors include economic structure, highway accessibility, air quality, the development level of the catering industry, and public market interest. [ABSTRACT FROM AUTHOR]
