中文摘要：

由于居民消费活动存在示范效应和收入效应，个体的跨期消费选择受到群体消费流动性的影响。为了在既定消费流动性的约束下讨论城镇家庭的跨期消费选择行为，本文首先结合中国家庭的消费特点改进了嵌套的跨期消费选择模型，分别讨论了暂时性收入冲击和持久性收入冲击对消费的拉动效果；其次，讨论了估计模型的模拟估计方法。最后，实证分析发现我国城镇居民的消费流动性与最终消费对经济增长的贡献率具有共变性、当期暂时性收入冲击拉动当期消费的效果明显大于前期该冲击的替代效应、以及持久性收入冲击拉动消费的效果低于暂时性收入冲击。

英文摘要：

Because of the demonstration and income effect of resident consumption activities, the individual＇s intertemporal consumption choice is impacted by the cohort consumption mobility. In order to discuss the intertemporal consumption Choice behavior of the urban households under the restraint of given consumption mobility, this paper takes into account characters of Chinese household consumption and improves the nested model of intertemporal consumption choice, discusses effects of transient and persistence income shocks on consumption respectively. Secondly, this paper discusses the simulation estimation methods of the model. Finally, by the empirical analysis we find that the consumption liquidity of urban residents have the same variability with the contribution rate of final consumption to economic growth, the effect of current consumption drove by current temporary income shocks is significantly greater than the substitution effect of shocks in the early, and the effect of consumption drove by persistent income shocks is lower than the temporary income shocks.
