摘　　要：笔者首先界定了收入两极分化的内涵,并使用ER指数测度了全国及各省区市城乡收入两极分化程度,实证结果表明:改革开放以来,我国城乡收入两极分化总体上有所加剧,且全国各省区市城乡收入两极分化程度各异,分布极不平衡,有显著的地域差异。随后,笔者依据人均GDP水平的高低,将全国31个省区市分为发达、较发达、欠发达三类地区,并对全国及各类型地区分别构建省级区域面板协整模型,结果发现:中国城乡收入两极分化与区域经济增长之间存在长期稳定的协整关系,两变量间呈反向变动关系,且经济越发达地区,ER指数对人均GDP的负面影响效果越显著。基于这样的结果,笔者提出了相应的政策建议。This paper defined the connotation of income polarization,and the degree of urban-rural income polarization in China and all provinces was measured using ER index. The empirical results showed that,the degree of urban-rural income polarization in China has increased in general since the reform and opening up,and the degrees of urban-rural income polarization among provinces were different; meanwhile,the distribution was extremely uneven with significant regional differences. Based on Per Capita GDP,all the 31 provincial areas were divided into three regions. Then we built a panelco-integrationmodel at the provincial level fornationaland different regional areas,revealing that there is a long-term stable relationship between Urban-rural Income Polarization and economic growth,and the ER index is negatively associated with the GDP per capita. Correspondingly,the negative effect on economic growth by polarization is more significant in the region at higher level of economic development. Based on this conclusion,this paper throws out some suggestions.
