摘要
选取2010—2019年中国运输机场货邮吞吐量数据,运用核密度分析、标准差椭圆和标准距离方法,研究航空货运市场时空演变特征。结果表明,1)2010—2019年我国机场数量增长显著,东西部差距较为明显,但中西部地区新增机场数量显著增多,机场分布逐渐趋向均衡化发展。2)航空货运市场呈现“3+1核心”的发展格局,中西部地区货运增长较快,市场集聚程度逐渐降低。3)航空货运市场重心由东向西偏移,2010—2013年向西北方向偏移,2013—2019年向西南方向转移。通过对我国航空货运市场时空演变特征的研究,能够为优化我国航空货运市场布局和制定货运发展政策提供理论依据。
Based on the air cargo volume of China's airports from 2010 to 2019,the spatial-temporal evolution characteristics of China's air cargo market were studied using kernel density analysis,standard deviation ellipse and standard distance method.The results showed as follows:1)The number of airports increased significantly from 2010 to 2019,with a significant gap between the east and west,but the number of new airports increased significantly in the central and western regions.The distribution of airports gradually forms a balanced development trend.2)China's air cargo market presents a pattern of"3+1 core".Due to the rapid growth of freight in the central and western regions,the degree of market agglomeration decreases gradually.3)The gravity center of air cargo market shifts from east to west,shifting to northwest during 2010-2013,and shifting to southwest during 2013-2019.The study of spatial-temporal evolution of Chinese air cargo market provides theoretical basis for optimizing Chinese air cargo market distribution and formulating policies for cargo development.
