摘　　要：本文以县域为研究单元,以人均GDP为测度指标,采用统计分析与EDSA相结合的方法,探索了1991年-2009年甘肃省县域经济发展差异的时间特征、空间格局及其演变过程。结果表明:甘肃省县域经济总体差异呈现扩大趋势,陇中、河西、陇东、陇南和南部民族地区5大经济区之间的差异及河西经济区内部差异是甘肃县域经济整体差异的主要贡献者;经济发展水平相似县域的空间集聚性不断增强,形成了发达的河西经济区及欠发达的陇南经济区和南部民族地区,而发达地区经济发展极化作用占主导且极化趋势在进一步加深,经济发展空间二元结构明显。Temporal feature, spatial pattern and its evolution process of economic development in Gan- su Province during 1991-2009 were probed into by the method of combining EDSA and Statistic analysis in the paper. The study was done on the base of county level and measured by the index of per capita GDP. The conclusions were found as follows, the total economic disparities of county level in Gansu Province en- larges, the integral economic disparities of county level in Gansu Province were bred by the disparity a- mong Central Gansu, Hexi, East Gansu, North Gansu and South Gansu ethnic areas and by the disparities inside West Gansu. The county with a similar level of economic development continuously enhances its spatial agglomeration, which produced the developed regions formed in Hexi, and the backward areas were mainly in the North Gansu, Central Gansu and South Gansu ethnic areas. Polarized function of economy in the developed regions played a leading role and the polarized tendency had further deepened in the economic development of Gansu province, and then the dualistic structures were significant.
