Abstract: Aviation logistics is an important part of building a powerful civil aviation country. With the increasing uncertainty in the world， aviation logistics has increasingly become an important carrier of highend industrial chain， efficient supply chain and advanced value chain. Airport takeoff and landing sorties and cargo and mail throughput are the key factors affecting the highquality development of aviation logistics industry. Why do airport takeoff and landing sorties affect cargo and mail throughput Which of these factors play a mediating and regulating role Bootstrap moderated mediation model was used to explore it. The results show that: the number of takeoff and landing sorties has a significant positive effect on the cargo and mail throughput of the airport; taking off and landing sorties indirectly improve the cargo and mail throughput of airport through the intermediary role of seasonal flight volume. The area of airport cargo station has a significant regulating effect on the mediating effect of flight volume during the season. Therefore， it is necessary to build firstclass air logistics facilities， improve the air logistics route network system， speed up the resumption of air logistics services such as flights that have been stalled due to the complexity of the environment， improve the service level of the air logistics industry， help the aviation supply chain to extend the chain and strengthen the chain， and promote the construction of China’s civil aviation and logistics power.

摘要： 航空物流是建设民航强国的重要内容。随着世界不确定性加剧，航空物流日益成为高端产业链、高效供应链和高级价值链的重要载体。机场起降架次和货邮吞吐量是影响航空物流业高质量发展的关键因素。使用Bootstrap有调节的中介模型探究机场起降架次何以影响货邮吞吐量，找出起中介作用和调节作用的因素。研究发现，起降架次对机场货邮吞吐量具有显著正向影响，起降架次通过航季航班量的中介作用间接提高机场货邮吞吐量，机场货站面积对航季航班量的中介作用具有显著调节效应。为此，需要建设一流的航空物流设施，完善航空物流航线网络体系，加快恢复因环境复杂性而停滞的航班等航空物流业务，提升航空物流业服务水平，助力航空供应链延链补链强链，推进中国民航强国和物流强国建设。
