长三角城市交通高质量发展评价及其空间差异

Evaluation of High-quality Urban Traffic Development in Yangtze River Delta and Its Spatial Differences

交通是城市发展的重要推动力之一,交通高质量发展成为各个城市发展的重要支撑。随着长三角一体化国家战略的不断推进,城市交通高质量发展受到学界广泛关注,关于其评价指标以及空间差异尚待深入研究。作者选取长三角41个城市为研究对象,借助熵权法,对2000—2021年交通高质量发展水平进行评价及动态演变分析。研究发现,长三角城市交通高质量发展水平经历了先下降再上升的U形演变过程,并具有进一步提升的趋势;长三角城市交通高质量发展水平空间差异较大,基础设施、交通服务、交通效益在这一过程中发挥了重要推动作用,空间联系的作用尚待加强。本研究提出了相应的提升优化策略,以期为长三角城市交通高质量发展提供参考。

Traffic is one of the important driving forces of urban development,and the high-quality development of traffic has become an important support for the development of cities.With the continuous promotion of the integrated national strategy of the Yangtze River Delta,the high-quality development of urban transportation has attracted extensive attention from academic circles,but its evaluation index and spatial differences need to be further studied.Therefore,41 cities in the Yangtze River Delta are selected as the research objects,and with the help of entropy weight method,the development capacity of high-quality transportation from 2000 to 2021 is evaluated and its dynamic evolution is analyzed.It is found that the development ability of high-quality urban traffic in the Yangtze River Delta is not high as a whole,and the development of high-quality urban traffic has experienced a "U"-shaped evolution process,which has a trend of further improvement.The Yangtze River Delta's high-quality transportation development capacity varies greatly in space,and the overall spatial structure presents a bow-and-arrow shape composed of central cities and coastal and inter-provincial border cities.Infrastructure,transportation services and transportation benefits have played an important role in this process,and the role of spatial links needs to be strengthened.In addition,this paper also puts forward the corresponding promotion and optimization strategies in order to provide reference for the high-quality integrated development of the Yangtze River Delta.
