中国城市竞争力区域差异的空间分析

Spatial Analysis on Regional Dif ference in Urban Competitive Powerin China

中国地级市及以上级别城市竞争力在东西向呈现出“高—低—高—低”四元结构的区域差异的特征,在南北向表现为北方沿边、沿江、沿南昆线3个高水平带及与其之间低谷带的相间分布;在区域及更小尺度上,存在由大城市向边缘其它城市逐步递减的“凸”字形空间格局;城市竞争力较高的城市集中于沿海、江、线、边地带。

The regional difference in competitive power for cities at and above prefecture level in China is characterized by the four-fold structure of 'high-low-high-low'.It is characterized by three high level areas of border-shore,river-shore and area bordering Nanning-Kunming Railway line in the south-north direction to the north and the alterna- tive distribution in the valley zones among them.At regional or smaller scale,a gradual degressive spa- tial pattern of ' 凸 'shape is formed for big city ex- pansion into the fringe area.Those cities with higher competitive power are centered along the sea-shore areas,river-shore areas,railway line-shore area and border-shore areas.
