摘　　要：改革开放以来,我国城乡居民收入差距不断扩大,各区域的城乡收入差距也形成一定的梯度差异。本文利用泰尔指数定量分析了我国东中西部地区城乡收入差距的区域差异,并运用动态因子模型的状态空间形式以及卡尔曼滤波原理,将我国泰尔指数序列分解成共同因子及区域特质因子序列。同时,选取了五个指标来研究城乡收入差距区域特质因子的影响因素,得出了各区域特质因子影响因素的动态系数序列。Since reforming and opening up, the residents＂ income gap between urban and rural is growing and has formed a certain gradient different regional urban - rural income gap. This paper employs the Theil index to measure the regional difference of income gap between urban and rural areas in the east, middle and the west areas and decomposes the Theil index into common factor and the regional idiosyncratic factor based on dynamic factor model in state - space form and the Kalman filter theory. Then the paper selects five indicators to build influencing factors which have impact on idiosyncratic factors of urban - rural income gap and thus working out the coefficient of every factor.
