【摘要】 利用变异系数、基尼系数、GIS空间分析等方法，剖析黄河流域区域经济差异的时空演化格局，并运用多尺度地理加权回归模型(MGWR)对其影响因素的空间异质性进行分析。结果表明：(1)2002—2020年黄河流域不同尺度区域经济绝对与相对差异均较为明显，区域经济差异从大到小依次为地级市、省级、城市群、上中下游。(2)2002—2020年黄河流域区域经济发展水平呈波动上升趋势，呈由东至西递减格局，且尺度越小区域经济异质性越强。(3)各影响因素呈现显著的空间分异格局，对黄河流域区域经济差异的影响具有不同的空间模式和影响范围。其中城镇化、分权化、产业结构对黄河流域地级市经济发展的影响从东至西递减，区域投资水平对黄河流域上游城市经济发展的影响较大，海拔对流域内城市经济发展的负向影响由东至西递增。更多还原

【Abstract】 This study explores the spatial-temporal evolution patterns of regional economic disparity in the Yellow River Basin using coefficient of variation, Gini coefficient, and GIS spatial analysis, and analyzes their influencing factors with the help of multiscale geographically weighted regression model. The results demonstrate that the absolute and relative disparity of regional economy at different scales in the Yellow River Basin are obvious from 2002 to 2020, and the regional economic differences, from large to small, are in the order of prefecture-level cities, provincial-level cities, urban agglomerations, upstream, midstream, and downstream. The regional economic development levels in the Yellow River Basin show an increasing trend from 2002 to 2020 showing a decreasing pattern from east to west, and the smaller the scale, the more obvious the regional economic heterogeneity. Using MGWR model analysis, it is found that the factors show significant spatial heterogeneity patterns and influence ranges on the regional economic disparity in the Yellow River basin. Among them, the influence of urbanization, decentralization, industrial structure and constant terms on the economic development of prefecture-level cities in the Yellow River Basin decreases from east to west. The regional investment level has a greater impact on the economic development of cities in the upper reaches of the Yellow River Basin. The negative impact of development increases from east to west.更多还原
