The National Bureau of Statistics released the national Consumer Price Index (CPI) and Producer Price Index (PPI) data with 2025 as the base year, marking the first data release after this base year rotation. After the base year rotation, changes in the survey classification catalog, survey points, representative specifications, and weights will all have some impact on the price index, but the direction and magnitude of these factors' effects vary, and their combined effect constitutes the overall impact on the total index.

According to calculations, the impact of this base year rotation on the year-on-year indices of CPI and PPI for each month averages approximately 0.06 and 0.08 percentage points, respectively, which is relatively small overall
