基于复杂网络的西南地区航线网络现状分析

Analysis of Current Situation of Airline Network in Southwest China Based on Complex Network

为更好地服务成渝地区双城经济圈,激发国内航空运输市场活力,利用民航比较优势建设国家综合立体交通网,畅通国内大循环。通过建立西南地区航线网络模型,运用复杂网络等分析方法,对西南地区机场城市的航线网络进行分析研究,为构建成渝世界级机场群以及西南地区网络规划提供参考。结果表明:西南地区虽然增加的航线与通航点较多,但内部离散程度在减小,西南地区航线网络呈现出从无序到有序的过程;西南地区是以四个省会机场城市为枢纽的轴-辐式航空网络;省会机场城市与非省会机场城市航线网络呈现出两级分化。

In this paper, in order to better serve the Chengdu-Chongqing economic circle and stimulate the vitality of the domestic air transportation market, we built the national comprehensive three-dimensional transportation network based on the comparative advantages of civil aviation to smooth the great domestic circulation system. By establishing the airline route network model for the southwest region, and using the complex network analytic method, we looked at the airline network of the airport cities in Southwestern China, which could provide reference for the construction of the Chengdu-Chongqing world-class airport cluster and the network planning in this region. The result of the analysis showed that despite the growing number of airline routes and points in the southwest region, the degree of its internal dispersion was decreasing, and the route network in this region was currently in the process turning from disorder to order;that of the southwest region would be a hub-and-spoke aviation network with four provincial capital airport cities as the hubs;and the route networks of the provincial capital airport cities and non-provincial capital airport cities would be more polarized over time.
