摘　　要：收入由多个来源部分组成,城乡收入差距的变化是收入来源各部分变动的综合反映,透过收入来源的角度可以清晰地判断城乡收入差距产生的根源。本文运用泰尔指数及其分解方法,对2003-2008年甘肃省城乡收入差距大小及其在总区域收入差距中的贡献变化趋势进行测度,并利用要素分解法实证分析了不同收入来源对城乡收入差距的影响,以此揭示甘肃省城乡收入差距产生的原因。研究发现,城乡收入差距在总区域收入差距中的贡献是递增变化的,已经成为影响甘肃省居民收入差距的重要因素;工资性收入是目前拉大城乡收入差距最为重要的原因,而家庭经营性收入则起着缩小差距的作用,转移性收入和财产性收入在总收入中所占比例很小,但转移性收入对城乡收入差距的贡献却不容轻视。基于研究结果,提出了增加农民非农收入、推进农业产业化进程和完善城乡间收入再分配制度等政策建议,以期为欠发达地区缩小城乡收入差距带来一些启示。Income is made up of many kinds of sources. And the change of the sources composing the income results in the change of urban and rural income disparity. Therefore, by analyzing the income sources we can get the essential causes of urban-rural income disparity. In this paper we use the Theil Index and its decomposition method to measure the rural-urban income disparity of Gansu Province and the variation trend of its contribution to the total region＇ s income disparity. Then we use the factor decomposition method to analyze the influences of different income sources on the rural-urban income gap and get the causes of the urban-rural income gap in Gansu Province. We find in our research that the contribution of rural-urban income disparity to the total region＇ s income disparities presents a climbing trend and it has been an important factor in affecting the income disparity of Gansu province. The income mainly from salary is the most important factor in widening the rural-urban income gap, while the income from household operations contributes to narrowing the gap. The proportion of the income from transfer and properties in the total income is very small, but the contribution of transfer income to the rural-urban income gap cannot be ignored. Based on the research results, we put forward some corresponding policy advice, such as increasing the peasant＇s non-agricultural income, promoting agricultural industrialization process, and improving the system of income redistribution between urban and rural areas, and to narrow the rural-urban income gap in those underdeveloped areas.
