基于2002-2008年间我国181个地级及以上城市的面板数据，通过构建人口城市化和土地城市化指标，采用动态面板模型探讨了城市化进程对城乡居民收入差距的影响效应。从全国总体样本来看，人口城市化进程和土地城市化进程均对降低城乡居民收入差距有显著作用，人口城市化进程的作用是土地城市化进程的近2倍。在分区域研究后发现，人口城市化指标对缩小城乡居民收入差距的作用在东中西部依然显著，且呈现出逐渐增大的趋势；而土地城市化指标的作用则在中部和西部地区显著为负，在东部地区并不显著，且从数值上也比人口城市化指标小得多。这说明人口城市化水平的提高是缩小城乡居民收入差距的重要因素，新型城市化的核心应是人口城市化。
基于2002-2008年間我國181箇地級及以上城市的麵闆數據，通過構建人口城市化和土地城市化指標，採用動態麵闆模型探討瞭城市化進程對城鄉居民收入差距的影響效應。從全國總體樣本來看，人口城市化進程和土地城市化進程均對降低城鄉居民收入差距有顯著作用，人口城市化進程的作用是土地城市化進程的近2倍。在分區域研究後髮現，人口城市化指標對縮小城鄉居民收入差距的作用在東中西部依然顯著，且呈現齣逐漸增大的趨勢；而土地城市化指標的作用則在中部和西部地區顯著為負，在東部地區併不顯著，且從數值上也比人口城市化指標小得多。這說明人口城市化水平的提高是縮小城鄉居民收入差距的重要因素，新型城市化的覈心應是人口城市化。

Based on the panel data consisting of 181 prefecture - level cities of China from 2002 to 2008, this essay constructs population urbanization indicators and land urbaniza- tion indicators, and investigates the effect of urbanization on ur- ban- rural residents＇ income gap by the dynamic panel data method. From the view of the overall sample, the process of population urbanization and land urbanization both reduce urban -rural residents＇ income gap and have a significant role, the role of population urbanization process is much larger than the role of the land urbanization, nearly two times of it. Through sub -regional research, it is found that it remains significant that population urbanization indicators reduce urban - rural resi- dents＇ income gap in the eastern, central and western areas, and present a gradually increasing trend. Land urbanization in- dexes remain negative and significantly only in the central and western regions while in the eastern region it is not significant, and has smaller effects on urban - rural residents＇ income gap. This shows that the improvement of population urbanization level is indeed one of the important factors to narrow urban - rural res- idents＇ income gap, and the key point of the new type of urbani- zation is population urbanization.
