| 摘 要： 在数理分析的基础上，运用2004—2014年面板数据实证研究城镇化对城乡收入差距影响的金融门槛效应和非线性特征。结果表明，城镇化有效抑制了城乡收入差距的扩大，且这一抑制作用随金融的不断发展呈现拉平的“S”型趋势；在金融发展水平低于阈值3.90时，城镇化对城乡收入差距扩大的抑制作用较强，高于该阈值时，抑制作用相对较弱；在金融发展水平相对较低的地区，城镇化发展对城乡收入差距扩大的抑制作用较金融发达地区而言更为显著。 |

| Abstract: Based on mathematical analysis, and employing the panel data from 2004 to 2014 years, the present essay investigates the non-linear characteristics and regional differences of the impact of urbanization on the urban-rural income gap at different stages of financial development. Research shows that urbanization inhibits the expansion of urban-rural income gap effectively, and this inhibition with evolving of finance presents the trend of flattened “S” type. When the level of the financial development is below the threshold of 3.90, the inhibitory effect of urbanization on the urban-rural income gap is strong, while above this threshold, the inhibitory effect is relatively weak. Especially in the regions where the level of financial development is relatively low, the inhibition of the development of urbanization to the expansion of the income gap is more significant compared with that in the financially developed regions. |
