不同的收入来源对区域间城乡收入差距具有不同的影响。基于收入来源结构的分析发现,三大区域工资性收入差距对城乡总体收入的贡献率最高,是影响城乡收入差距扩大的主要收入来源,东部地区工资性收入差距的贡献率高于中部和西部地区。经营性收入差距具有缩小城乡收入差距的作用,但其在总收入中所占比重较小,对缩小城乡居民收入差距的作用不断降低,西部地区经营性收入对缩小城乡居民收入差距的作用相对较小。财产性收入在城乡居民收入中所占比重较小,其对城乡居民收入差距的贡献率并不明显。转移性收入差距在扩大城乡收入差距方面发挥了重要作用,在东部地区尤为显著。
Different sources of income have different impacts on the income gap between urban and rural areas in the region. Based on the analysis of income source structure, it is found that the wage disparity in the three regions has the highest contribution rate to urban and rural overall income, which is the main source of income that affects the widening income gap between urban and rural areas. The contribution rate of wage disparity in eastern regions is higher than that in central and western regions . The operating income gap has the effect of narrowing the income gap between urban and rural areas, but its proportion in the total income is small, and its role in narrowing the income gap between urban and rural residents is declining. The operating income in western China has a relatively smaller effect on narrowing the income gap between urban and rural residents small. The share of property income in the income of urban and rural residents is small, and its contribution rate to the income gap between urban and rural residents is not obvious. The transfer income gap has played an important role in widening the income gap between urban and rural areas, especially in the eastern region.
