摘　　要：辐射域竞争与协同态势,体现了多机场系统内各机场的竞争力。本文基于Lotka-Volterra模型对区域多机场系统内的交叉腹地进行竞争均衡研究,以机场综合实力为影响因子,选择各机场在交叉腹地的市场份额为因变量,求解两机场间的竞争稳定状态及满足条件。以长三角机场群内南京禄口机场、杭州萧山机场的腹地交叉区域为例,对其进行数值仿真。结果表明,当两机场间的综合实力比值均大于腹地交叉区域旅客对相应机场的需求量时,两机场将实现各自在辐射域交叉部分的竞争均衡。这为机场提升自身在区域多机场系统内的竞争力提供了一种理论分析方法。The competition and cooperation of radiation domain reflects the competitiveness of the airports in the multi-airport system.Based on Lotka-Volterra model,this paper studies the competition equilibrium of the cross hinterland for the regional multi-airport system.Taking the comprehensive strength of airports as the influencing factor,the market share of each airport in the cross hinterland is selected as the dependent variable to solve the competitive stable state and the required conditions between the two airports.Taking the cross hinterland of Nanjing Lukou Airport and Hangzhou Xiaoshan Airport in the Yangtze river delta airport group as an example,the numerical simulation is carried out.The results show that when the comprehensive strength ratio of the two airports is greater than the demand of the corresponding airport in the hinterland cross region,the two airports achieve the competition equilibrium in the cross region of the radiation domain.This provides a theoretical analysis method for an airport to improve its competitiveness in a regional multi-airport system.
