摘要基于多尺度分析视角,综合运用差异指数、尺度方差、空间关联及回归模型等方法,从省级、地级、县级3个空间尺度分析了2003-2016年东北地区城乡收入差距时空演变特征及影响因素。结果显示:①城乡收入差距绝对和相对差异、尺度方差及构成均呈现县级>地级>省级的尺度发展格局,各尺度变化趋势大体一致,表明空间尺度越小,区域差异越大。②城乡收入差距空间分异特征明显,地级和县级尺度分别以中等和较低城乡收入差距为主要发展类型;城乡收入差距空间集聚特征明显,地级尺度关联性较强,县级尺度差异性较强;各尺度局部空间关联以显著正相关为主且LL型占据主导地位,各尺度冷热点集聚格局总体保持一致。③自然基础与区位、经济发展与支撑、社会发展与支撑、发展战略与政策共同推动各尺度城乡收入差距时空分异格局的形成及演化。④更加关注多尺度的实体区域研究、更加区分多指标体系与多因素分析、更加关注定性与定量方法有效结合是今后研究城乡收入差距的发展方向。 Based on multi scale analysis perspective,this paper comprehensively used a variety of methods,such as the difference index,the scale variance,the spatial correlation and the regression model,based on three scales of provincial,prefectural,county,to analyze the temporal and spatial evolution characteristics and the influencing factors of the urban-rural income gap in the Northeast of the 2003-2016.The results indicated that:①The absolute and relative differences,scale variance and composition of the urban-rural income gap showed a scale development pattern of county-level > prefecture-level > provincial-level,the trend of changes in each scale was generally consistent,indicating that the smaller the spatial scale,the greater the regional differences.②The spatial differentiation of urban-rural income gap was obvious,and the middle and low income gap was the main development type at the prefecture level and county level.The spatial agglomeration characteristics of urban-rural income gap were obvious,and the correlation was strong at the prefecture level,and the difference was strong at the county level;The local spatial correlation and significant type of each scale were all positively correlated,and the LL type takes the lead.The overall development pattern of cold and hot spots on each scale remained consistent.③Natural basis and location,economic development and support,social development and support,development strategies and policies jointly promote the formation and evolution of spatial and temporal patterns of urban-rural income disparity.④More attention is paid to the multi scale entity regional research,the more distinguishing multi index system and the multi factor analysis,and more attention to the effective combination of qualitative and quantitative methods,which was the direction for the future research of urban-rural income diffraction.
