中国三大区域间收入不平等影响因素的实证研究:1952-2008

An Empirical Research on the Influencing Factors of China's Income Inequality among the Three Regions: 1952-2008

区域收入不平等的持续增大,对个人与群体的尊严、国家经济的可持续性发展形成严峻挑战。以往研究局限于经济学视角,只关心某一或某几种因素对收入不平等影响,过于碎片化。本文利用1952-2008年国家统计数据,基于结构主义视角,通过随机效应模型考察了区域间收入不平等背后的因果机制。研究发现:经济增长与区域间收入不平等存在微弱倒"U"关系;结构因素是构筑区域收入不平等的主要力量,解释比例达到69.7%。本文认为,"非均衡发展"是中国经济转型与发展过程中必然的路径选择,区域收入不平等不可避免,并将长期存在。

The continuing enlarging of income inequality among the three regions of China has made a great threat to the dignity of individuals, affecting development of country＇s economy. Previous research only concerns one or some variables＇ influence on income inequality and is limited to economic view. Using annual statistics data for 1952-2008 period published by China Bureau of Statistics and random effect model, based on structural theory, the paper analyzes the cause mechanism of income inequality among different regions. The research shows there is a mild inverted U relation between economy growth and regional income inequality. Structural variables are the main factors causing income inequality and it explains about 69.7% of income inequality. So, the author thinks ＂the Unbalanced Development＂ is a necessary path when China is experiencing a process of economy institution changing and social developing. The inequality is inevitable and will exist for a long time.
