摘　　要：基于中国339个地级及以上城市2002~2014年的城乡收入比重数据,综合运用空间自相关、空间变异函数、克里格插值等方法,分析了近13 a间中国地级及以上城市城乡收入差距的空间分布格局与演变特征。结果表明,2002~2006年中国地级及以上城市城乡收入差距呈不断扩大的趋势;中国城乡收入差距的空间集聚程度明显,西部和中部地区是城乡收入差距较大的热点地区,东部地区为冷点地区,说明中国城乡收入差距地区发展不平衡;中国城乡收入差距存在明显的空间异质性,即各地区城乡收入差距高低的相互作用和联动效应较为显著。Based on the urban-rural residents income ratio data of 339 prefecturelevel cities or above in China from 2002 to 2014, we used the methods of the spatial autocorrelation, the semivariogram function, Kriging spatial interpolation to analyze the spatial pattern and change characteristics of the urban-rural income gap of prefecture-level cities or above in China. The results show that the urban-rural income gap is increase from 2002 to 2006. The urban-rural income gap shows clusters phenomenon obviously. H-H area are sheet distribution in the central and western regions of China, and L-L area are scattered distribution in the eastern regions of China, which indicates a significant non-equilibrium development of the urban-rural income gap in China. The urban-rural income gap has an obvious spatial heterogeneity.
