新时期沿黄省会城市商业空间结构及其空间服务能力

在“黄河战略”和推动供给侧结构性改革的双重背景下,考察沿黄城市商业空间格局对推动黄河流域城市经济高质量发展意义重大。以沿黄省会城市为例,通过核密度估计、标准差椭圆方法分析其商业空间结构,进而通过叠加分析方法探讨等级商业空间服务能力。结果表明：（1）市区人均社会消费品零售总额自黄河上游到下游总体呈现递增趋势,济南是典型的积极消费型城市;（2）沿黄省会城市商业空间格局呈现出串珠型、单核心型、基础网络型、成熟网络型;（3）城市商业空间结构越成熟,空间服务能力越强,济南市等级商业空间服务能力显著,郑州市最差。研究结果能够为新时期黄河流域高质量发展与国土空间规划提供科学参考。

Research on commercial spatial structure and spatial service capability of provincial capital cities along the Yellow River in the new period

Under the dual background of the"Yellow River Strategy"and the promotion of supply-side structural reform,it is important to investigate spatial structure of urban commerce of capital cities along the Yellow River so as to promote the high-quality development of the Yellow River Basin’s urban economy.This paper takes the provincial capital cities along the Yellow River as an example,analyzes their commercial space structure through the kernel density estimation and the standard deviation ellipse method,and explores the level of commercial space service capabilities through overlay analysis.The results show that:(1)The total sales of social retail products per capita in the urban area shows an increasing trend from the upper to the lower reaches of the Yellow River Basin.Along the river,Jinan is a typical active consumer city.(2)The commercial spatial structure of the capital cities along the Yellow River shows beaded type,single core type,basic network type and mature network type.(3)The more mature the urban commercial spatial structure becomes,the stronger its spatial service capability is.Jinan has the most significant commercial spatial service capacity,and Zhengzhou has the worst.The research results can provide a scientific reference for the highquality development of the Yellow River Basin and land spatial planning in the new period.
