# 基于SVAR模型对商品价格波动和居民消费关系的讨论 Discussion Based on the SVAR Model of Commodity Price Volatility and Consumer Relations

This paper tries to analyse the relationship between the retail price index and consumer price index with the structural vector auto regression (SVAR) model when it was 2000 to 2012 monthly. With the VAR model we have the unit root test, in which we get the long-term stable relationship between two variables in the model analysis. With their own pre-impact, the retail price has a significantly positive effect on the consumer price (which affects coefficient of 0.44). On this basis, with the establishment of the impulse response function we make (SVAR) model impulse response function analysis.
