城市群功能分工的时序演变与区域差异

The Sequential Evolution and Regional Differences among The Functional Division of Urban Agglomerations

运用空间功能分工指数对中国城市群功能分工进行了测度,并对其时序演变与区域差异进行了分析。结果显示:2003—2011年,城市群功能分工水平总体相对较低且呈现出金字塔式分布特征,东部地区城市群功能分工程度远远高于东北地区和中西部地区。从城市群功能分工区域差异来看,四大区域呈现出明显的空间分异特征,中西部城市群基本上呈现出波动中上升的态势,而东部城市群则呈现出波动中持续下降的趋势。从城市群功能分工时序演变特征来看,城市群功能分工演变态势大体上以2010年为拐点,出现了整体上由波动中上升向迅速下降的转变。

This paper measures the functional division of Chinese urban agglomeration by the index of space function division and analyzes its sequential evolution and regional differences. The results show that from 2003 to 2011, the overall level of urban agglomemtions functional division is relatively low, presenting a pyramid dis- tribution. And the level of urban agglomerations functional division of the eastern region is much higher than that of the Northeast and Midwest. From the regional differences of the functional division in urban agglomerations, the four major regions show significant regional differences. Midwestem cities basically show increase tendency in fluctuation while eastern cities a dechning tendency in volatility. From the sequential evolution of the functional division of urban agglomerations, the year 2010 is the turning point. Before 2010 there is a increase in fluctuation while it deehnes rapidly after 2010.
