PPI及货币供应量对CPI的影响

The Impact of PPI and Money Supply on CPI

影响CPI的外因包括广义货币供应量M_2和工业品出厂价格指数PPI两方面.由于这些变量之间可能存在着多重共线性,为了缩小变量的范围,采用计量经济建模工具Eviews软件对影响CPI指标的M_2、PPI及其影响时滞进行线性回归分析,从而得到现行CPI预测指标.

The paper analyzes the impact of external factors of CPI including broad money supply M2,the producer price index PPI.Because many of the variables affect the CPI may exist multicollinearity among them,the paper chooses appropriate variables to minimize the scope,uses econometric modeling tools of software Eviews to conduct linear regression analysis on M2 and PPI which affecting CPI index and the impact delay,and then obtains current CPI index for predictions.
