我国推进城市改革以来城乡两极分化的演化——基于居民收入的实证分析

Positive Analysis about the Evolution of the Polarity Between Urban and Rural Areas of China since the City Reform

通过对我国城乡居民收入的两极分化演化及发展趋势进行实证分析，1990～2006年期间，我国居民收入两极分化与这一时期的改革历程是基本吻合的，并且总体上在震荡中上升，但上升速度低于收入差距扩大的速度；当前我国居民收入两极分化的程度是比较适度的，并且在一个时期内还将会在震荡中略有上升。在此基础上提出了要减缓或降低收入两极分化上升速度的相关政策建议。

A positive analysis about the evolution and trend of the polarity of urban and rural residents' income from 1990 to 2006 suggests that the income of the residents increased in an oscillation,but the rate of increase is much lower than the rate of the income gap extension.The degree of the income polarity is modest and keeps in pace with the City Reform of China.And the polarity will last for a certain period.Some countermeasures are proposed based on the positive analysis.
