- Abstract
Point-to-point airlines through hub airports constitutes the trunk network system, which plays a key role in the whole air traffic organization. Based on the panel data of 2012 and 2018, this paper constructs a series of indicators set, aiming to explain the impact of airline network on the spatio-temporal distribution of flight delays and forecast its change trend with a seven- year comparison. The results are as follows: ①Airline network is the external basis of spatiotemporal distribution of flight delays, and the cumulative effect and the peak effect of delays are caused by the two components of airlines and airports, respectively. The high delay rate of hub airports cannot be completely attributed to the poor airport construction and air traffic control, which is closely related to the airline network, including the strength and structure of network connection. ②The degree of airline connection in China is more than the degree of aviation demand, and its oversaturation state is obvious and mainly exists between the composite hub airports. The intra-day delay frequency changes from a low value and increases continuously until the end. The overlap of peak hours forms delay contagion and spread, and produces the cumulative effect of flight delay. ③The high node degree and intermediary center of hub airports lead to the low degree of agglomeration and average path length index of the overall route network. The central advantages and bridging functions of hub airports lead to an oligarchic structure of network connection, resulting in the top effect of flight delay. ④The pattern of China's airline network is relatively fixed in the past seven years, and it is still facing great challenges to reduce flight delays. Optimizing air traffic functions and implementing flow regulation are an important direction of airspace reform.
