中文摘要	区域经济空间结构和区域经济差异历来是国内外学者关注的热点问题。在特定的时间背景下,区域经济差异在空间上就表现为该区域某一时段的经济空间结构,区域差距变化在空间上就表现为区域经济空间结构的演变趋势。运用变差系数和空间自相关模型,以县域为基本空间单元,以人均GDP为衡量指标,对成都都市圈县域经济发展差异和经济空间结构演变的时候特征进行了分析。变差系数分析表明,成都都市圈县域经济差异在研究时段内大致沿"倒U型"的变化轨迹,县域经济差异不断缩小。通过县域人均GDP的全域自相关分析发现,Moran’sI从1999年的0.70下降到2007年的0.66,说明从总体上,成都都市圈经济空间结构的集聚效应是减弱的。局部自相关分析将成都都市圈59个县分为4种县域类型(HH、HL、LL和LH),HH和LL型县域数量在研究时段内有所增加,HH县域绝大部分都集中分布在成都和德阳两市所辖的县域内,而LL型县域分布在距成都较远的区域,表明成都都市圈县域经济空间相关程度有所提高,形成了较为明显的发达地带和边缘贫困地带。
英文摘要	Spatial economic structure and regional economic disparities have always been a hot issue for scholars at home and abroad.In the context of a certain time,change in regional economic disparities can be used to show the evolution of the spatial economic structure of certain region.Coefficient of variation and statistical techniques were applied to analyze the evolution of economic spatial-temporal disparities and spatial economic structure in Chengdu metropolitan region by using county as a spatial unit and per capita GDP as measuring index for the level of regional economic development.The CVs curve for inter-county exhibit an invert U shaped pattern from 1999 to 2007 in Chengdu metropolitan region.From the temporal change of the spatial autocorrelation,we found that the Moran’s I decreased from 0.70 in 1999 to 0.66 in 2007,which demonstrated that the disparity between rich and poor clusters was narrowed in the same periods.Moran’s I scatter plot divided the 59 counties of Chengdu metropolitan region into four types(HH,HL,LL,LH), and the number of HH and LL counties increased from 18 in 1999 to 28 in 2007.By making LISA(Local Indicators of Spatial Association) map,we found all the HH counties located in Chengdu and Deyang,and most of LL counties located far from the economic center of Chengdu metropolitan region.From the whole Chengdu metropolitan region,the clustering effect showed a decreasing trend from 1999 to 2007,but in some areas,polarization effect is increased,and regional disparities were still significant. 更多
