本文在文献综述的基础上,指出了现有研究中的不足,即缺少不同收入阶层的消费过度敏感性的分析以及由于样本容量的不足导致模型拟合及预测能力不强。本文主要利用panel data模型分析了我国城镇不同收入阶层居民消费的过度敏感性,验证出各阶层都存在着过度敏感性,且过度敏感性的大小在各阶层中呈现倒“草帽”型分布。 Based on the literature review, this paper points out the shortcomings of the existing research, namely, the lack of analysis of excessive consumption sensitivities of different income groups and the weak ability of model fitting and forecasting due to the lack of sample capacity. This paper mainly uses the panel data model to analyze the over-sensitivities of residents in different income groups in urban China. It verifies that all classes are over-sensitive and the size of over-sensitivity shows “straw hat” distribution in all classes .
