长三角城市群高铁网络与经济联系网络的演进与比较研究

The Evolution and Comparative Study of the High Speed Rail Network and Economic Connection Network in the Yangtze River Delta Urban Agglomeration

采用引力模型构建长三角经济联系网络,通过长三角高铁线路构建高铁网络,分析两种网络的演进过程,同时比较两种网络在演进过程中的相同点与差异,结果表明:1) 长三角城市群高铁网络与经济联系网络都形成了上海、南京、杭州三个增长极点,以及若干个次增长极点,并一起构成了两条横向的发展轴线。2) 长三角城市群高铁网络与经济联系网络在演进过程中出现了个体的差异性,这种差异分为两种类型,第一种类型是城市较早融入高铁网络,但其经济联系并没有得到显著提升;第二种类型是城市经济联系强度较高,但高铁建设水平较低,对其经济联系的支持作用有限。

The gravity model is used to build the Yangtze River Delta economic connection network, and the high-speed rail network is built through the Yangtze River Delta high-speed rail line. The evolution process of the two networks is analyzed, and the similarities and differences between the two networks in the evolution process are compared. The results show that: 1) The high-speed rail network and the economic connection network of the Yangtze River Delta urban agglomeration have formed three growth poles of Shanghai, Nanjing and Hangzhou, as well as several sub-growth poles, which together constitute two horizontal development axes. 2) There are individual differences in the evolution of high-speed rail network and economic connection network in the Yangtze River Delta urban agglomerations, which can be divided into two types. The first type is that cities integrated into high-speed rail network earlier, but their economic connection has not been significantly improved;The second type is that the intensity of urban economic ties is high, but the level of high-speed rail construction is low, and the support for its economic ties is limited.
