家庭债务对收入不平等与消费不平等间关系的调节效应:2004—2012

The Moderating Effects of Household Debt on Income Inequality and Consumption Inequality: 2004- 2012

采用2004—2012年31个省市自治区的面板数据,构建主效应模型和调节效应模型,验证了收入不平等对消费不平等影响的主效应,以及家庭债务等变量对收入不平等与消费不平等间关系的调节效应。结果表明:从全国层面来看,收入不平等与消费不平等具有显著的正相关关系,但收入不平等程度低于消费不平等程度。家庭债务对收入不平等与消费不平等之间的关系具有较强的调节作用,在一定程度上缩小了收入不平等与消费不平等之间的差距;从区域层面来看,高债务地区的收入不平等低于消费不平等,低债务地区的收入不平等高于消费不平等。

Based on the 2004- 2012 provincial panel data,we establish the main effect model and the moderating effect model to examine the relationship between income inequality,household debt and consumption inequality. The results show that： from the national level,there is a significant positive correlation between income inequality and consumption inequality,but income inequality is lower than consumption inequality. Household debt has a significant moderating effect on income inequality and consumption inequality,narrowing the gap between income inequality and consumption inequality. From the regional level,income inequality is lower than consumption inequality in the high debt region while higher than consumption inequality in the low debt region.
