摘要
【目的】为了研究长江经济带城市高质量发展水平与高铁网络发展水平之间的协同发展程度。【方法】利用熵权法测算了2008—2020年长江经济带106个城市的经济高质量发展水平,并结合社会网络分析法,综合测算了高铁网络发展水平。随后,运用耦合协调模型,分析两个系统之间的耦合协调度。并在此基础上,运用莫兰指数研究耦合协调度的空间效应。【结果】结果表明,长江经济带整体的高铁网络发展水平和城市经济高质量发展均逐年提升,两者间的耦合协调度在空间上呈现正相关性,但存在发展不均衡的现象。其中,长江下游地区和A类城市两个系统间的耦合协调度提升相对较快,明显高于其他地区。值得注意的是,在长江经济带的高铁网络中,一些城市具有显著的控制力和影响力,而另一些城市则几乎被边缘化。【结论】长江经济带城市经济与高铁网络协同发展稳步向好,在后续的政策制定中,应确保高铁能够服务到各个重要节点,更好地促进城市间经济的互联互通。
【Objective】In order to explore the degree of synergy between the level of high-quality development of cities in the Yangtze River Economic Belt and the level of high-speed rail networks.【Method】In this paper,the entropy power method was used to measure the level of high-quality economic development of 106 cities in the Yangtze River Economic Belt from 2008 to 2020,and the level of high-speed rail network was comprehensively measured by combining the social network analysis method.Subsequently,the coupling coordination model was applied to analyse the degree of coupling coordination between the two systems.And on this basis,the spatial effect of the degree of coupled coordination was investigated by using the Moran index.【Result】The results show that both the level of high-speed railway network and the high-quality development of urban economy in the Yangtze River Economic Belt as a whole have been improving year by year,and the degree of coupling and coordination between the two shows a positive correlation spatially,but there is a phenomenon of un-balanced development.Among them,the degree of coupling and coordination between the two systems in the lower reaches of the Yangtze River and Class A cities has improved relatively fast and is significantly higher than that in other regions.It is worth noting that some cities have significant control and influence in the HSR network of the Yangtze River Economic Belt,while others are almost marginalised.【Conclusion】The synergistic development of the urban economy and high-speed rail network in the Yangtze River Economic Belt has been steadily improving,and in the subsequent policy formulation,we will try to ensure that the high-speed rail will be able to serve all important nodes,and better promote the economic interconnection between cities.
