基于面板结构突变的居民消费结构实证分析

Empirical Analysis of the Consumption Structure of Residents Using Structural Break

摘要


居民消费结构是否稳定历来都是宏观经济调控者研究的重点和热点之一,当重大的经济变量遭受冲击后,居民的消费结构可能会发生改变,从而研究居民消费结构是否因收入差距扩大或金融危机等重大冲击的影响有重要的理论和实际意义。本文基于面板回归模型对中国城乡居民2003到2011年的收入消费季度数据进行了实证分析,并引入了结构突变理论对居民的消费行为稳定性进行研究,结果显示2008年居民消费结构发生了结构突变。更进一步分析得出重大的经济环境改变会影响居民消费行为,城乡居民消费结构在突变前后呈现三大特征:城镇居民改变消费行为的时间晚于农村居民;中等消费水平的居民改变消费习惯的时间早于其他居民;突变前后城乡居民自发消费水平和边际消费倾向都有所改变。因而在制定居民消费政策时,要考虑到城乡居民消费行为的差异制定不同的消费政策,提高农村居民收入,才能扩大消费和拉动经济增长。

This paper considers problems related to panel regression using structural break in consumption behaviors of stability for urban and rural residents. We draw conclusion that consumption behaviors were changed by the economic environment, the impact of break to the date occurred around 2008. The stability of rural residents' consumptions are weaker than urban residents, median consumption group adjust the consumption habits are faster than others. After break, self-consumption expenditure and the marginal propensity to consume of the urban and rural residents has to change. Our findings have important policy implications since they reveals that we should pursue differentiated consumption policies for different residents respectively.
