摘要
采用非线性定量分析工具——分形分析方法,构建分形维数模型,对1996年—2009年间中国城镇居民收入分布分形维数值进行测算,研究了城镇居民收入差距的演变趋势。研究结果发现:其一,城镇居民收入分布具有明显的分形特征;其二,1996年—2009年间城镇居民收入差距不断扩大,扩大速度因时而异,扩速有放缓趋势;其三,以居民收入为表征的分形双对数曲线呈现不规则移动。最后,就如何控制和缩小城镇居民收入差距提出对策建议,为研究居民收入差距提供了一种新的方法。
Quantitative analysis of the nonlinear tool（method of fractal analysis） is employed to construct the fractal dimension model.Then the model is used to measure the fractal dimensions of urban residents income distribution during 1996-2009 in China,and to study the evolution of urban income gap trend.The results show： first,the distribution of income of urban residents has obvious fractal characteristics;second,during1996-2009 years,the income gap between urban residents expands and the speed varies with time,having a slowing down trend;third,the fractal double logarithm curve characterized by resident income irregularly moves.Finally,some suggestions are made for how to control and reduce the income gap between urban residents.This provides a new approach for studying income gap between urban residents.
