【摘要】：在控制消费习惯形成因素基础上,采用OLS和双胞胎组内差分法,就真实的预防性储蓄动机强度的估计以及消费者异质性与预防性储蓄动机的关系提出了一个基本分析思路。从中国国情出发,建立了预防性储蓄动机实证模型,并试图通过微观数据的搜集,分析消费者异质性与预防性储蓄动机强度的关系。通过比较同卵双胞胎数据的组内差分估计、异卵双胞胎数据的组内差分估计与混合OLS的估计结果,得出真实的预防性储蓄动机强度、不可观测的个体储蓄行为导致的预防性储蓄动机强度与消费习惯形成下的预防性储蓄动机强度。
[Abstract]:On the basis of controlling the forming factors of consumption habits, using OLS and the intra-group difference method of twins, this paper puts forward a basic analytical thought on the estimation of real precautionary saving motivation intensity and the relationship between consumer heterogeneity and precautionary saving motivation. Based on the situation of China, this paper establishes an empirical model of precautionary saving motivation, and attempts to analyze the relationship between consumer heterogeneity and the intensity of precautionary savings motivation through the collection of microcosmic data. By comparing within-group difference estimation of identical twins data, intra-group differential estimation of fraternal twins data and mixed OLS estimation results, the true intensity of precautionary saving motivation is obtained. The intensity of precautionary saving motivation caused by unobservable individual saving behavior and the intensity of precautionary saving motivation under the formation of consumption habits.
