Spatiotemporal Pattern of Urban-Rural Income Gap of Prefecture Level Cities or Above in China
分析了2000-2011年中国343个地级及以上城市城乡收入差距的时空格局、空间自相关和影响因素，发现中西部差距大于东部，人力资本投入比、二三产业集聚等扩大差距，而城乡劳动比缩小差距。
Taking the residents income ratio between urban and rural residents as the measuring indicator,this paper analyses the spatiotemporal pattern,global trends,spatial heterogeneities and correlations of income gap of 343prefecture-level cities or above in China from 2000 to 2011 by use of ESDA-GIS,semi-variant function,gravity center migration and trend surface analysis. Spatial lag model is established to estimate the effect of each explanatory variable and analyze the impact factors of urban-rural income gap. The results show as following. The spatial difference of income gap between urban and rural residents is significantly, showing a trend of the middle Chinathe western Chinathe eastern China,and the Centralthe Souththe North. The calculate result of Moran's I shows that the density of urbanrural income gap of prefecture level cities or above in China has a significant and growing global spatial autocorrelation characteristic and spatial cluster,regional disparities trend of income gap is more and more obvious. The gravity center of urban-rural income gap had moved northeast on the whole from 2000 to 2011. The western and northeastern areas are the significantly reduced area in urban-rural income ratio,while the Yellow River basin is the most concentrated areas where the income gap significantly expanded. Cold spot areas of urban- rural income gap have spread markedly,and the spot areas shrink dramatically. Urban- rural human capital inputs ratio,agglomeration of the secondary and tertiary sectors,urbanization rate and spatial lag variable all have positive effects on urban- rural income gap,whereas the urban- rural labor ratio has negative effect on urban-rural income gap.
