满足消费最大化的最优居民收入差距研究

本文运用中国20年来的数据,估算了使居民消费最大化的城乡、城镇内部收入差距的最优路径.研究发现我国实际城乡、城镇内部收入差距不仅高于最优路径,而且偏离最优路径的程度正在扩大.城镇内部收入差距对最优路径的偏离超过了城乡收入差距对最优路径的偏离,而且城镇内部收入差距正在以更快的速度偏离最优路径,这说明城镇内部收入差距抑制消费需求的强度更大.要扩张居民消费,就必须采取措施缩小居民收入差距,尤其是缩小城镇内部收入差距.本文的实证分析为缩小居民收入差距的方向和力度提供了一个客观的、可操作的参照系.

Researches on the optimal resident income gap for maximizing the consumption

Given the data of twenty years in China, this article estimates the optimal path for the income gap inside the urban areas as well as between the urban and rural areas so as to maximize the resident consumption. The results show that the real gap is larger than the optimal level and the deviation from the optimal path is expanding. The situation inside the urban areas, with a faster pace, seems worse than that between the urban and rural areas, which indicates that the income gap inside the urban areas constrains consumption in a greater extent. Increasing resident consumption needs shortening the income gap, especially the gap inside the urban areas. The empirical analysis in this article provides an objective and practical reference for the task.
