chapter two, we described the income disparity objectively and carried on the analysis of different stages . chapter three, we made comparative analysis of the income disparity between urban and rural residents among provinces by using linear regression and correlation analysis from the view of spatial distribution and time series . as to the reasons that made the synchronous and asynchronous income disparity change between provinces and whole country, we also made elementary analysis 第三章,对各省城乡居民收入差距进行了省区间比较的实证分析,采用了回归分析和相关性分析的方法,从空间分布和时间序列变化两个方面对省区间的城乡居民收入差距进行了初步研究,揭示了城乡居民收入差距在空间布局以及时间序列变化上的不同步性;同时,还对形成这种空间不平衡和时间变化不同步的原因进行了初步探讨。
