中国城镇家庭消费不平等分布测度研究

Study on the Distribution Measurement of Urban Households' Consumption Inequality in China

文章基于中国跨省区城镇家庭调查数据,本文对我国城镇家庭消费与收入进行了不平等指数测度;采用适应性核密度估计与相对分布法模拟了两阶段城镇家庭消费的分布情况与变动趋势。研究结果表明,我国城镇家庭消费不平等与收入不平等的变化趋势具有一致性,消费不平等程度高于收入不平等;随着我国经济的发展,我国城镇家庭消费的整体水平得到提高,中高消费水平家庭比重不断增加,其中高消费家庭的比例增加更为显著,消费不平等呈现逐渐增加的趋势。

This paper aims to measure the distribution of China＇s urban household consumption inequality. First, based on the survey data about China＇s inter-provincial urban household, the paper measures inequality indexes of urban households＇ consumption and income in China. Second, the paper uses adaptive kernel density estimation and relative distribution methods to simulate distribution and trend of urban households in two stages. The paper shows that urban households＇ consumption inequality is more than income inequality; with the development of China＇s economy, overall level of China＇s urban households＇ consumption has been improved, the proportion of households in middle and high consumption level gradually increase, especially, the proportion of high- spending households increases more significantly, and consumption inequality is showing a growing trend.
