Based on the panel data from 148 cities in China's aviation sector spanning the period of 2011-2020,this research explores the influence of air transportation linkage networks on tourism economic devel-opment.The research employs various methodologies,including complex network analysis,non-radial Super-SBM model,spatial Markov chain,and dynamic spatial panel Durbin model,to explore spatial evolu-tion patterns and provide empirical evidence.The findings reveal that air transportation linkage networks ex-hibit a core sub-network characterized by a"diamond"or"overlapping triangle"structure,strengthening net-work balance,stability,and overlapping effect.The community structure demonstrates an"intertwined and overlapping"pattern in the central-eastern region,while the western region features"edge cities in close proximity".The spatial distribution of tourism economic efficiency levels follows an east>southwest>cen-tral>west pattern,the hierarchical solidification of spatial evolution is clearly characterized.Different from the empirical results obtained from previous researches,this research reveals that when a city becomes con-nected to aviation,it immediately benefits from positive tourism factors due to the spillover of aviation ad-vantages from neighboring cities.Finally,to avoid the negative consequences of agglomeration under bal-anced competition,China should promote inter-city tourism capital flows,industry-related division of labor cooperation,and knowledge and technology spillover.
