航空运输业是网络型基础产业,因此航空运输系统具有网络特性,大量经济研究明确了航空运输业的规模经济、范围经济和网络经济的现象和理论范畴,而由于航空运输成本计量方式的复杂性,由此使得对航空运输业网络经济的评估变得十分困难。一方面,作为为旅客提供位移服务的运输产品,在不同的运距、不同的起讫点,甚至不同的时刻上都是 Air transport industry is a network-based industry. Therefore, the air transport system has network characteristics. A large number of economic studies have made clear the phenomenon of scale economy, range economy and network economy of the air transport industry. Due to the complexity of air transport cost measurement methods, , Thus making the assessment of the network economy of the air transport industry very difficult. On the one hand, as a transport product that provides displacement services to passengers at different distances, different origins and even different times
