中文摘要：

利用2000—2013年江苏省13地市的面板数据考察江苏省出口贸易对城乡收入差距的影响,采用静态面板数据模型和动态面板数据GMM模型实证分析江苏省不同区域的出口贸易、高等教育发展与城乡收入差距之间的关系以及作用机制,研究结果显示：对于整个江苏省以及苏南地区而言,出口贸易、高等教育发展均扩大了城乡收入差距;对于苏中地区而言,出口贸易、高等教育发展扩大了城乡收入差距,且高等教育的中介效应显著;对于苏北地区而言,出口贸易、高等教育发展均为缩小城乡收入差距做出了显著贡献,且高等教育这一中介变量显著缩小了该地区的城乡收入差距;此外,所有地区的城乡收入差距均具有自我强化的作用。

英文摘要：

Using the panel data of thirteen cities in Jiangsu province from 2000 to 2013,this paper studies the effects of the export trade on urban-rural income gap in Jiangsu province. Based on the static panel data model and dynamic panel data of GMM model,this paper makes an empirical analysis on the relationship and mechanisms of export trade,development of higher education and urban-rural income gap in the different regions of Jiangsu province. The findings are as follows： Firstly,for the overall,the south of Jiangsu and the middle of Jiangsu,the export trade and the development of high education have expanded urban-rural income gap. In addition,for the middle of Jiangsu,the higher education has a significant mediating effect.Secondly,for the north of Jiangsu,the export trade and the development of higher education have made significant contributions to narrow the urban-rural income gap,and higher education as a mediating variable significantly narrows the urban-rural income gap. Lastly,the urban-rural income gap has self-reinforcing effect in all regions.
