摘要：
Aviation network traffic has increased day by day, and operations between airports are closely coupled. Airport risk diffusion has grown to be a major issue that affects their ability to operate safely and effectively. However, the spread mechanism of airport risk at the network level has not yet been fully understood. This paper first proposes an airport risk coupling quantification method based on clustering algorithm and taking into account multiple risk factors, then constructs risk time series and applies causality testing methods to construct airport risk propagation network in order to better study the mechanism of airport risk propagation at the network level. By comparing the performance of different types of networks, analyzing the characteristics of risk propagation networks, and studying the overall characteristics and laws of risk propagation. The findings demonstrate that the degree distribution of the risk propagation network meets the requirements for dual-zone logarithmic distribution, exhibits small-world properties, has a small network width and high community, and can be separated into a number of densely connected areas. The low network efficiency of the risk propagation network indicates that it is more difficult for the risk to spread globally. © 2023 Beijing University of Aeronautics and Astronautics (BUAA).
