中国民用航空网络的中心-外围模式

民用航空网络是航空运输的重要载体.航空运输网络的发展状态决定着民用航空的根本运行效率.本文以中国民用航空网络为研究对象,应用中心-外围理论,对中国民用航空网络的整体结构布局进行了研究.发现中国民用航空网络存在典型的中心-外围模式,中心节点分别是北京、上海、广州,外围节点对中心节点存在距离依赖,且对北京节点的距离依赖最强.中心节点的正影响距离约在500–555 km范围处,其整体影响距离呈现“∽型”变动趋势,可以看作是中国民用航空网络的“脊背”.同时,地区教育水平、经济发展、总人口数量均对节点发展产生正向影响,地理面积和固定资产投资水平对节点发展存在负影响.各节点发展程度还随着年份的递增而增加.

Core-Peripheral Model of Chinese Civil Aviation Network

Civil aviation network is an important carrier of air transport. The development situation of air transport network determines the fundamental operating efficiency of civil aviation. In this paper, the author studies Chinese civil aviation network’s overall structure with the application of core-periphery theory. It is found that there is a typical core-periphery model in Chinese civil aviation network with three central nodes: Beijing, Shanghai and Guangzhou. The peripheral node’s exists distance-dependently on the central nodes, and Beijing has the strongest influence. Core nodes’positive impact distance ranges from 500 to 555 km with the overall "∽ type" fluctuant trend, which can be seen as civil aviation network backbone of China. Meanwhile, the education level, regional economic development and the number of the total population have a positive impact on the development of nodes. There is a negative impact on the node development with geographic area and the level of investment in fixed assets. And the level of development of each node will increase with years.
