摘要
本文利用1985-2007年各行业人员平均收入和各年人均GDP数据,根据我国行业收入差距的现状计算并度量了行业收入差距的基尼系数,并由计算的基尼系数和我国实际人均GDP的变动特征建立了我国行业收入差距与经济增长的协整模型,实证研究结果表明,我国行业收入差距与经济增长存在长期稳定关系,且行业收入差距对经济增长的长期效应取决于行业收入差距水平和经济发展阶段。我国改革开放初期的行业收入差距对经济增长具有促进作用,而现阶段行业收入差距的扩大对经济的长期增长产生阻滞作用。研究进一步估计和分析误差修正模型,表明了我国行业收入差距与经济增长的长期稳定关系对短期经济增长没有显著影响。并提出缩小行业收入差距的相应政策建议。
This paper studies the stage effects of Chinese income disparity between industries. We measure the Gini coefficient index and specify a cointegration model with respect of income disparity and economic growth. The results of cointegration model indicate that there is a long-term eointegration relationship between income disparity and its economic growth. And it depends on the level of income disparity and the economic stage. The cointegration implies that the effect of income disparity to economic growth is positive at the beginning of Chinese reform. However, the effect is negative at pre- sent. We estimate and analyze the ECM. The result shows that the widening of income disparity doesn＇t effect the economic growth in the short term. Therefore, we should take measures to reduce income disparity.
