由于历史和现实的原因,中国存在着较大的城乡收入差距。如果以城乡居民在收入均值上的差异作为城乡收入差距的一个度量,那么中国的城乡收入差距居于全世界前列。城乡收入差距也是全国范围内收入不均等的重要原因。最新研究成果表明,在纠正收入定义、城乡价格指数、居民结构等因素导致的估计偏差之后,城乡居民收入比率从2002年的2.2倍上升到了2007年的2.9倍,而城乡收入差距对全国收入差距(以泰尔指数为度量)的贡献则从2002年的30%增加到2007年的41%
Due to historical and practical reasons, China has a large income gap between urban and rural areas. If we take the difference between urban and rural residents in the mean of income as a measure of urban-rural income disparity, the income gap between urban and rural areas in China will be among the highest in the world. Income gap between urban and rural areas is also an important reason for income inequality across the country. The latest research results show that the income ratio of urban and rural residents rose 2.9 times from 2.2 times in 2002 to 2.9 times that of 2007 after correcting the estimated deviation caused by the definition of income, urban-rural price index, residential structure and other factors. However, the difference between urban-rural income gap and national income gap (Measured by the Theil index) increased from 30% in 2002 to 41% in 2007
