- Abstract
The Consumer Price Index (CPI) is an important indicator to measure the level of inflation in our country. It reflects the impact of commodity price changes on the daily lives of residents. It is an important basis for governments at all levels to carry out fiscal policies and the central bank to formulate monetary policies. CPI data reflecting economic phenomena have obvious seasonal time series characteristics. By extracting a total of 59 months from January 2017 to November 2021 in our country, a seasonal differential autoregressive moving average model (SARIMA) is established for empirical analysis and prediction. The results show that SARIMA (0, 1, 0) (0, 1, 1)12 has a high degree of fitting and can better reflect the future trend of my country’s CPI. Based on this, using this model to predict the trend of my country’s CPI in 2022, it is found that my country’s CPI will remain stable at about 102% in 2022, which provides a certain reference for the decision-making of the government, enterprises and other market entities.
