摘　　要：高铁发展对城市居民收入差距的影响对推进中国共同富裕进程至关重要。使用1999~2020年城市面板数据研究区域高铁网络增密如何影响城市居民收入差距,同时基于流动人口集聚视角进行机理分析。研究发现:第一,区域高铁网络增密对城市基尼系数存在显著U型影响;第二,流动人口集聚弱化是区域高铁网络低密度增密缩小城市居民收入差距的重要原因,流动人口集聚强化是区域高铁网络高密度增密扩大城市居民收入差距的重要原因;第三,区域高铁网络低密度增密更有利于东部地区、收入差距较大以及非高铁枢纽城市缩小居民收入差距。因此,为缩小城市居民收入差距,政府应加大对高铁网络低密度区域的高铁网络建设力度。The impact of high-speed rail(HSR)development on income inequality among urban residents is crucial for advancing China’s goal of shared common prosperity.Using urban panel data from 1999 to 2020,this study examined how the densification of regional HSR networks affects income disparities among city dwellers,focusing on the mechanism of migrant population aggregation.The research found several key insights.Firstly,the densification of regional HSR networks exhibits a significant U-shaped effect on cities’Gini coefficients,indicating varying impacts depending on network density.Secondly,in regions with low HSR network density,the aggregation of migrant populations helps reduce urban income inequality,whereas in high-density HSR network regions,it tends to exacerbate it.Lastly,low-density densification of the HSR network is particularly beneficial for narrowing income gaps in eastern regions,areas with significant income disparities,and cities not designated as HSR hubs.To effectively diminish urban income inequality,the government should prioritize expanding the HSR network in regions currently lacking density,aiming to enhance infrastructure connectivity and promote socioeconomic integration across regions.
