中文摘要：

本文运用空间功能分工指数对中国城市群的功能分工水平进行了测度与比较。结果显示：2003--2010年，中国城市群功能分工水平总体相对较低并呈现出波动中持续下降的趋势，但2008年之后呈现出一定程度的上升态势：城市群功能分工存在明显的区域差异，东部城市群高于中西部城市群且差距逐渐拉大。从城市群中心城市与外围城市的比较来看，中心城市远远高于外围城市且二者差距不断扩大，但中心城市自身则呈现出下降趋势。从城市等级角度比较来看，城市功能分工水平与城市等级高低有关，不同等级的城市呈现出明显的级差特征。

英文摘要：

The paper measures and analysis the degree of functional urban specialization of Chinese urban agglomeration. The results show that, the functional urban specialization of Chinese urban agglomeration has been decreasing annually from 2003 to 2010 on the whole, hut it shows the trend of increasing since 2008. There is the regional difference between areas. The eastern areas are higher than the middle and western areas, and its gap is gradually expanding. The functional urban specialization of core cities is higher than the periphery cities and its gap is gradually expanding, but the index of core cities is decreasing by itself. Also, the more high the urban hierarchy, the more high the functional urban specialization, and there is differential characteristics between different urban hierarchies.
