一、经济增长与收入差距关系的理论分析美国经济学家库兹涅兹通过实证研究,以人均财富增长为横坐标,以人均财富分配为纵坐标,建立坐标系得到如下曲线。库兹涅兹认为,在处于经济起步阶段的农业社会,收入分配相当均等。工业化开始后,经济快速增长,人均财富分配不平衡明显加剧,曲线上扬。之后的一段时间内,工业化完成之后,收入分配不平衡缩小,曲线下降,从而形成倒U形。库兹涅兹曲线的核心观点是:经济增长对收入分配的影响必然 First, the theoretical analysis of the relationship between economic growth and income gap The United States economist Kuznets through empirical research, with per capita wealth growth as abscissa, the per capita wealth distribution as the ordinate, the establishment of coordinate system to get the following curve. Kuznets believes that in the agricultural economy in its infancy, income distribution is fairly equal. After the industrialization started, the economy grew rapidly and the imbalance in the distribution of wealth per capita increased apparently and the curve went up. After a period of time, after the industrialization was completed, the imbalance in income distribution narrowed and the curve declined, thus forming an inverted U-shape. The core point of the Kuznets Curve is that the impact of economic growth on income distribution is inevitable
