摘要
我国城镇内部面临收入差距的不断扩大和消费一直不振的双重问题。笔者选取城镇最高20%收入组（高收入群体）和城镇最低20%收入组（低收入群体）作为城镇居民的代表阶层,以这两个阶层之间的收入差距来代表城镇内部居民收入差距。通过建立满足消费最大化的最优收入差距理论模型,利用我国1985年~2009年统计年鉴数据和MATLAB数学软件测算出我国城镇内部最优收入差距路径,为以扩张消费为目的的收入再分配提供有意义的参照系。
The urban areas of our country face the dual problems of widening income gap and continued consumption slump.The authors selected the 20% highest income group（high-income group） and 20% lowest income group（low-income group） in urban areas as the representative classes of urban residents and used the income gap between these two classes to represent the income gap within urban areas.By establishing the optimal income gap theoretical model based on consumption maximization and using the data of 1985-2009 statistical yearbook and MATLAB mathematical software,the authors measured the optimal income gap within the rural areas of our country and provided a significant frame of reference for the income redistribution aiming at expanding consumption.
