Research on the Influencing Effect between CHVA and CPI in China Based on VAR Models

The cointegration test, granger causality test, VAR model, impulse response function and other econometric methods are used in this paper to analyze the influencing effect between commercial housing vacancy rate and CPI and its delay impact. The results show that there is a long-term equilibrium relationship between commercial housing vacancy rate and CPI in China. There are at least one cointegration relationship between CHVR and CPI. The past values of the CPI appear to contain information which is useful for forecasting changes in the CHVR. CPI has a significant effect on CHVR and CPI rising drives CHVR.
