【摘要】：通过将习惯偏好引入传统的AIDS模型,进一步纳入退休冲击变量,构建了拓展的动态LA/AIDS模型。随后按照各省城镇居民可支配收入将全国分为高收入、中等收入和低收入地区,基于2003—2014年中国26个省城镇居民面板数据,利用系统广义矩估计方法,实证分析了习惯形成、退休冲击对中国不同收入等级地区城镇居民消费结构的影响;同时用FE-IV估计法对相应的静态模型进行估计。实证结果表明:(1)各收入地区城镇居民消费支出均显示出了显著的习惯形成特征,惯性最强的是食品消费支出份额,惯性最小的是家庭设备。(2)退休冲击对城镇居民消费结构的影响在中等收入地区和高收入地区显著,而在低收入地区不显著。在控制了习惯形成效应后,退休冲击对消费支出份额的影响程度均变小了。
[Abstract]:By introducing habit preference into the traditional AIDS model and further incorporating the retirement impact variable, the extended dynamic LA/AIDS model is constructed. Then, according to the disposable income of urban residents in each province, the whole country is divided into high income, middle income and low income regions. Based on the panel data of urban residents in 26 provinces of China from 2003 to 2014, this paper empirically analyzes the influence of habit formation and retirement impact on the consumption structure of urban residents in different income levels in China by using the method of system generalized moment estimation. At the same time, the FE-IV estimation method is used to estimate the corresponding static model. The empirical results show that the consumption expenditure of urban residents in different income regions shows significant habit forming characteristics, the most inertia of which is the share of food consumption expenditure. The least inertia is that the impact of retirement shock on the consumption structure of urban residents is significant in the middle and high income areas, but not in the low income areas. The impact of retirement shocks on the share of consumer spending has become smaller.
