基于产品异质的汽车需求理论分析与实证检验

从产品异质的角度分析中圆人均收入水平与人均汽车拥有量之睫的荧系，结果表明：实际人均GDP与人均民用载客汽车拥有量都是囝阶平稳的时间序列，两者之阃存在协整荚系，实际人均GDP对人均民用载客汽车拥有量存在Granger因果性。人均汽车拥有量的收入弹性大，弦与理论分析中关于收入分布参数的假设一致。

Theoretical Analysis and Empirical Test on Automobile Demand Based on Product Heterogeneity

This paper studies the relationship between per capita income and per capita automobile possession in China from the perspective of product heterogeneity.The results of the study show that the time sery of real GDP per capita has the same unit roots with passenger automobile possession per capita.There is a co-integration relationship between the two time series.The real GDP per capita has Granger causal effect on passenger automobile possession per capita.The numerical value of the income elasticity of automobile possession per capita agrees with the hypothesis on the parameter in income contribution.
