中国农村居民收入增长及空间差异演变

考虑到惯用的可分解组合的锡尔系数的缺点，故用独立锡尔系数对中国改革开放以来不同地理空间单元的农民收入差异情况进行测度。研究认为：农民收入差异在拉大，大部分省域农民收入水平都低于全国平均值，农民收入水平从东向西呈阶梯状分布；1995年以来．不同地理空间范围内的农民收入差异具有分层现象，差异程度由高到低依次是东西部、南部、全国、北部、东中部、东部、中西部、西部、中部；中部、西部、中西部的省际差异不大，其余层次的省际差异突出。全国、南部、北部、东部、东中部、东西部省际差异的演变轨迹高度相关，它们与中部、西部、中西部省际差异的演化轨迹负相关。

The Growth of Rural Peasants' Income and Its Spatial Evolution in China

Use independent Theil index to study the gaps of rural Peasants＇ income in different geographical units in China since 1978. The results indicate that the gaps are large between high income and low income. The inequality degree of eastern and western regions,southern regions, nationwide, northern regions, eastern and central regions, eastern regions, central and western regions, western regions, central regions are successive reduction. The provincial gaps of rural Peasants＇ income are small in central and western regions, western regions,central regions. But, in other regions, the gaps are large. There is a strong linear relation among eastern and western regions, southern regions, nationwide, northern regions, eastern and central regions, eastern regions in the evolution track of Theil index, but they have negative linear relation with the evolution track of central and western regions,western regions, central regions.
