一、引言库兹涅茨写于1955年的研究收入不均和经济增长之间关系的有创见的论文着重探讨以下两个方面的问题:一,在纯粹经验的水平上,他采用时间数列资料来检验三个国家的收入不均和经济增长的关系。他发现收入不均随着经济增长而得到缓解;二,库兹涅茨提出了一种二部门模型,它含有部门内和部门间两种不同的收入不均。由于劳动力从部门内收入较均衡和平均收入较低的农业部门转向工业部门,在经济增长的过程中,收入不均在初始阶段中恶化,而在恶化达到高峰后,又开始缓解。他用数字实例来表达这种在 I. INTRODUCTION Innovative papers by Kuznets, written in 1955 to study the relationship between income inequality and economic growth, focus on the following two issues: First, at purely empirical levels, he uses time series data To test the relationship between income inequality and economic growth in the three countries. He found that income inequality eased with economic growth. Second, Kuznetsi proposed a two-department model that included two different income inequalities within and among departments. As the labor force shifted from the agricultural sector with more balanced income and lower average income in the sector to the industrial sector, the income inequality deteriorated in the initial stage during the course of economic growth and began to ease after the deterioration peaked. He uses numerical examples to express this
