对口支援政策对收入分配公平的效应分析——来自新疆的检验

Analysis on the Effect of Counterpart Support Policy on Income Distribution Equity——A Test from Xinjiang

本文运用二嵌套Theil指数分解方法,以新疆14个地州2005年—2015年的数据为基础,研究新疆居民收入差距的变动状况及形成原因,并在此基础上检验了对口支援政策对新疆居民收入分配的公平效应。结果显示:对口支援后,新疆居民收入总体差距有较大幅度降低,城乡居民收入差距是引起居民收入总体差距变动的主要因素,地区内部收入差距和地区间收入差距对总体收入差距的影响相对有限。实证检验发现,对口支援政策实施能够显著缩减新疆居民收入总体差距,收入分配公平效应显著,特别是有助于改善城乡居民收入分配公平状况。因此,本文建议今后对口援助重点应向受援的农村地区倾斜,提高受援地区农村居民"造血型"收入的能力。

This paper uses the two-nested Theil index decomposition method to study the changing conditions and formation mechanism of income inequality in Xinjiang based on the data of 14 regions and prefectures in Xinjiang from 2005 to 2015,and it tests the effect of pairing assistance policy on income inequality.The results show that the overall income gap in Xinjiang has been greatly reduced after the counterpart support.The income gap between urban and rural areas is the dominant factor causing the overall income gap.The internal and external regional income disparity has relatively limited impact on the overall income gap.the empirical test found that the implementation of counterpart support policies could significantly reduce the overall income gap in Xinjiang,especially to help shrink the income gap between urban and rural areas,income distribution fair effect was significant,but it would significantly widen the income gap between regions,and had been no significant impact on the internal income gap.
