预防性储蓄的空间探索

Spatial Econometric Exploration of Precautionary Saving An Empirical Study Based on Chinese Urban Residents

本文在假设我国省域居民消费存在空间依赖性的前提下,对原有预防性储蓄模型进行空间计量改造,建立了我国居民预防性储蓄的空间计量模型,并选择面板数据模型进行实证研究。结果表明:①我国城镇居民消费存在显著的空间依赖性;②空间效应的存在可以缓减不确定性、流动性约束以及潜在流动性约束等对居民消费行为的影响,长期来看,可以平和居民一生的消费。

This paper is written on a hypothetical basis that the consuming behaviors of the domestic residents are with spatial dependence.It establishes the spatial panel data model by modifying the previous precautionary saving model.And the result of empirically study shows that： 1.The residents＇ consuming behaviors in China is with significant sptial dependence.2.The spatial effects can mitigate the effect of the consuming uncertainties and liquidity constraints.Therefore,in the long term,the spatial effects can leverage the residents＇ consumption of life.
