摘　　要：本文运用空间计量方法,利用31省市2003-2010年的相关数据,对农村正规与非正规金融对城乡收入差距的影响进行了实证分析。首先,通过对Moran’I指数和散点图进行分析,发现城乡收入差距之间存在显著的空间自相关。其次,通过建立SLM、SEM和SDM三种空间计量模型检验了农村正规与非正规金融对城乡收入差距的影响。结果表明,农村正规金融与非正规金融都对缩减城乡收入差距具有积极的促进作用,但是农村非正规金融的影响更为显著;农村正规金融与非正规金融的空间变量对缩减城乡收入差距的影响显著。Based on the relevant data of 31 provinces in China from 2003 to 2010,this paper conducts spatial econometric analysis to the influence of informal and formal rural finance on urban-rural income gap.Firstly,we find significant spatial self-correlation exists in the urban-rural income gap by positively analyzing the Moran’I index and scatter diagram.Then,we verify the influence of informal and formal rural finance on urban-rural income gap by building three kinds of spatial econometric models including SLM、SEM and SDM.The result shows that the informal and formal rural finance has played a positive promoting role in reducing urban-rural income gap.But the informal rural finance has more obvious effect on it.The influence of spatial variables of informal and formal rural finance on reducing urban-rural income disparity is significant.
