摘　　要：2000年以来西部地区发展的空间格局发生了很大变化,内部分化日益突出。优化发展空间格局是解决西部地区发展不平衡、不充分问题的重要途径。论文采用重心轨迹、Theil指数等方法定量研究了2000—2019年西部地区12个省(区、市)多尺度空间发展格局及区域差异的变化。结果表明:①西部地区发展的空间格局变化具有明显的阶段性。2000—2010年人口和经济重心向偏北移动,西北地区发展总体好于西南地区,西部地区区域发展总体差距不断扩大;2010年之后,人口和经济重心开始向偏南移动,西南地区的发展明显优于西北地区,区域发展总体差距也呈现缩小态势。②西部地区区域发展差异的变化存在显著的空间异质性和多样性。远西部和近西部地区的发展差距虽然较小,但呈现持续扩大的态势;西南与西北的人均GDP差距以及西部地区城乡居民收入差距均呈现先扩大、后缩小的倒“U”型趋势;西北地区内部和西南地区内部的农村居民收入差距均不断缩小,但差距依然较大;而西北和西南地区之间的农村居民收入差距虽有扩大趋势,但差距并不显著。③各省(区、市)的发展态势分化明显,形成4种不同的发展类型。最后,提出了西部地区未来发展空间格局优化策略。Since 2000,great changes have taken place in the spatial pattern of the development in western China,and the internal differentiation has become increasingly prominent.Optimizing the spatial pattern of development is an important way to solve the problem of unbalanced and inadequate development in the western region.This study used the trajectory of gravity center of development and Theil index to examine the change of the spatial pattern of development and regional inequality at different spatial scales in western China from 2000 to 2019.The results show that:1)The change of the spatial pattern of development of the western region showed obvious stages.From 2000 to 2010,the population gravity center and economic gravity center moved northward,and the development in the northwest was better than that in the southwest generally.The overall regional development inequality in the western region had been widening.After 2010,the population and economic gravity centers began to move southward,and the development in the southwest was obviously better than that in the northwest.The overall gap in regional development was also narrowing.2)There was a significant spatial heterogeneity and diversity in the changes of regional development inequality in the western region.Although the economic gap between the far west and the near west was small,it continued to widen since 2005.The per capita GDP gap between the southwest and the northwest and the income gap between urban and rural residents in the west show an inverted U-shaped trend.Although the income gap of rural residents in northwestern China and southwestern China had been narrowing,the gap was still significant.The income gap of rural residents between northwestern and southwestern areas had shown a widening trend,but the gap was not significant.3)The development trend of the provinces showed a clear differentiation,forming four different types of development.Finally,the article put forward the strategy of optimizing the development pattern of the western region in th
