居民地区收入差距对居民收入差距的贡献度有多大——以2008年为例的探讨

A Study on the Contribution of Regional Income Gap on Residents' Income Gap—Cased with 2008 Data

居民地区收入差距是居民收入差距的重要组成部分。在居民收入差距的形成中,主要归因于省内差距,这一比例占到74%,其余的26%由省际间地区收入差距解释,省际间地区收入差距的绝大部分又归因于东中西部地区间的收入差距。在省内差距中,城乡间收入差距之于居民收入差距的解释度超过40%,它与省际间地区收入差距一起,解释了居民收入差距的四分之三。目前的居民地区收入差距程度已经过大,这需要政府采取得力措施以应对,在此过程中应重视人口大省的收入分配问题并注重政策制定的差别化。
