Abstract
With the improvement of the income level of people, our country's economic level has continued to improve. However, due to the differences in geographical and historical conditions in various regions, there is a large gap in the level of economic development in various regions of our country, and there are also significant differences in the prices of different commodities. This article uses the multiple linear regression and Principal Component Analysis (PCA) by SAS to explore the impact of the Retail Price Index (RPI) and different factors, such as the Producer Price Index (PPI) of agricultural production materials and the PPI of industrial production, the Purchasing Price Index (PRI) of industrial producers, and the Price Index of Investment in Fixed Asset.
