三重城镇化影响城乡收入差距的空间效应研究——基于不同空间权重矩阵下的动态空间面板模型

Spatial Effect of Triple Urbanization on Urban-rural Income Gap:Based on Dynamic Spatial Panel Models with Different Weight Matrixes

结合我国城镇化特征,构建不同空间权重矩阵下的动态空间面板模型,分析我国内地除西藏以外的30个省份人口、资本和土地三重城镇化对城乡收入差距的影响。结果表明:我国各地区城乡收入差距存在显著的时空双向正相关;人口城镇化和资本城镇化有利于缩小城乡收入差距,而土地城镇化则扩大了城乡收入差距;基于邻接距离和地理距离的空间溢出是各变量影响城乡收入差距产生空间溢出效应的主要渠道。

Based on the characteristics of urbanization in China,dynamic spatial panel models under different spatial weight matrices are constructed to empirically analyze the impact of population,capital and land urbanization on urban-rural income gap.The results show that there is a significant spatial-temporal positive correlation between urban-rural income gaps in different regions.Population urbanization and capital urbanization are conducive to narrowing the urban-rural income gap,while land urbanization widens the urban-rural income gap.Spatial spillover based on proximity distance and geographical distance is the main channel of spatial spillover effect.
