江苏多尺度下城乡收入差距时空演变及影响因素

采用变异系数、泰尔指数、探索性空间分析和空间计量回归等方法,从市级、县级两个尺度分析2010—2020年江苏省城乡收入差距时空演变特征及影响因素。结果显示：2010—2020年江苏省两尺度下城乡收入差距呈缩小趋势,空间上呈现“南高北低”分布特征;县级尺度空间集聚特征明显,局部空间关联以“L-L（低-低）”和“H-H（高-高）”占主导,且空间集聚程度逐步增强;农业现代化、公共服务、居民生活水平、对外开放程度是影响江苏县域城乡收入差距的重要因素。

The Spatio-temporal Evolution and Influencing Factors of Urban-rural Income Gap in Jiangsu Province at Different Scales

Based on the method of coefficient of variation, Theil index, exploratory spatial data analysis and spatial econometric regression, the spatio-temporal evolution characteristics and the influencing factors of the urban-rural income gap in Jiangsu Province from 2010 to 2020 are analyzed. The results reveal that the urban-rural income gap in Jiangsu Province is narrowing on different scales, with the spatial evolution characteristic being "high in the south and low in the north". The characteristics of spatial agglomeration are obvious at county level, in which case the local spatial correlation is featured by "L-L(low-low)" and "H-H(high-high)" structure, and the degree of spatial agglomeration becomes enhanced gradually. Agricultural modernization, public services, living standard and the level of opening to the outside world play important roles in affecting the urban-rural income gap in Jiangsu Province.
