中国城乡收入差距的动态变化及影响因素研究

Research the Dynamic Fluctuation and Influence Factors of Urban-rural Income Gap in China

在新古典二元经济理论框架下度量中国城乡收入差距,按照产业的耦合程度将我国30个省划分为4个综合经济区,并采用灵活性傅立叶函数对我国省际城乡收入差距的收敛性进行检验。研究发现我国大西南综合经济区的城乡收入差距具有稳定收敛的特点,二元结构发展模式弱化,符合中国城镇化进程中的发展特点。而大西北、中南(未含广东和海南)和中北综合经济区(未含陕西)的城乡收入差距均表现为发散的趋势,二元经济结构特征明显。

This paper combines new classical dual economic theory to measure urban-rural income gap, dividing the 30 provinces （municipalities and autonomous regions） into four integrated economic areas. We use flexible Fourier function proposed by Enders and Lee （2012） to test the stability of inter-provincial urban-rural income gap. The empirical results show that the income gap between urban and rural is obviously heterogeneity in China; the income gap of Southwest integrated economic area is convergence and stable. The income gap of Northwest integrated economic area, South integrated economic area （except for Guangdong and Hainan） and North integrated economic area （except Shaanxi） show diverging trends, indicating that the diverging areas fit the dual economic structural theory.
