从发展经济学观点看待库兹涅茨假说──兼论中国收入不平等扩大的原因

Kuznets Hypothesis Viewed from the Theory of Economics of Development: On the Causes for the Enlargement of Income Inequality in China

关于描述经济增长与收入分配关系的库兹涅茨假说是否存在在学术界长期争论不休。本文把人类发展指数作为发展水平的指标，得出了库兹涅茨倒Ｕ型曲线，并用发展经济学的观点从理论上支持了这一假说。本文认为，库兹涅茨假说在中国也存在冲国收入分配不平等的扩大主要是由经济不平衡发展引起的。结论是，收入分配不平等的扩大是一个低收入国家快速经济增长和结构转变的必经阶段。

It is a long and endless academic contention whether Kuznets Hypothesis can be verified that describes the relationship between economic growth and income distribution. In this article, we, taking the exponent of human development as the index of the growth level, have succeeded in drawing the inverted U - shape curve of Kuznets Hypothesis, and in, theoretically, supporting this hypothesis by the use of economics of development. This hypothesis, we think, has been also proved here in China- the widening inequality in income distribution in China is sparked off mainly by the imbalance in economic growth. Our conclusion: the enlargement of income distribution is a phase that can not be leaped over in a low income country with rapid economic growth and in transit of system.
