摘　　要：ER型指数测算表明,中部地区88个地市(州)城乡居民收入两极分化程度存在明显的时空变化和地区分异;根据2000年、2009年各地市ER指数值,分别将88个地市分为四大类型区,根据2000—2009年各地市ER指数值的变化情况,将88个地市又分为三类地市,综合分析2000—2009年中部地区城乡收入两极分化程度的时空特征变化。分析结果显示:2000—2009年,中部地区城乡收入两极分化程度越来越严重,绝大多数地市的城乡收入极化程度变化呈现出加速上升或一般化上升趋势,各省城乡居民收入两极分化程度也有很大差别;城乡收入极化程度各类型区的空间分布情况发生了明显的变化,各省收入极化程度变化不同类型区的分布存在明显的差异。Income distribution inequality has always received concerns from all sectors of the society. Recent- ly, income polarization began to receive attention of researchers. The degree of urban-rural income polariza- tion changes with eonomic growth. For the need of comprehensive analysis on the temporal-spatial character- istics of the degree change of urban-rural income polarization in 2000-2009, the authors use the data of 2000 and 2009 and the measure method of degree of income polarization to calculate ER index for all 88 prefec- ture-level cities firstly. Then the authors divided those 88 cities into four categorical regions based on the re- suits of the degree of urban-rural income polarization in 2000 and 2009 separately, includes serious region, relatively serious region, general region and not obvious region, and divided 88 cities into three categorical regions based on the degree change of urban-rural income polarization, includes accelerated upward trend re- gion, general upward trend region and moderate weakening region. The analyzed results show that the degree of ubran-rural income polarization become more serious in the period of 2000-2009 and there is an accelerat- ed upward trend or general upward trend for the degree change of urban-rural income polarization in most cities. The number of the most serious region is much larger than the number of the general region and not obvious region. Based on the analysis on the spatial distribution of four categorical regions with different de- gree of polarization in 2000 and 2009 separatively, it is can be seen that there is a significant change about the overall spatial distribution.
