通达性,是指从一个地方到达另一个地方的容易程度。传统的通达性测算采取空间距离法、拓扑距离法、旅途距离法。基于时间价值理论的机场通达性评价研究,突破传统物理通达的观察角度,关注旅客出行便捷度,利用因子分析从变量群中找出机场通达的隐形影响因子。研究表明,北京首都、广州、上海虹桥综合通达性排名最高,昌都、凯里、阿里等支线城市排名靠后,实证结果客观反映出我国航空网络机场的通达性现状。
Accessibility is the easiness to reach one place from another. The traditional accessibility measures to take space distance method, distance method, travel distance method. Based on the time value theory of airport accessibility research, breaking the traditional perspective of physical access, focusing on passenger travel convenience, the use of factor analysis from the variable group to find out the airport accessibility invisible factors. The research shows that Beijing Capital, Guangzhou and Shanghai Hongqiao have the highest comprehensive accessibility ranking, and the rankings of the sub-cities such as Qamdo, Kaili and Ali are in the lower ranks. The empirical results objectively reflect the current status of the accessibility of China’s aviation network airports.
