Consumer price statistics survey the final price of social products and services, which is closely related to people's lives and occupies an important position in the whole national economic price system. It is an important indicator of economic analysis and decision-making, monitoring and regulation of the overall price level and national economic accounting. Its change rate reflects the degree of inflation or deflation to some extent. Generally speaking, inflation is considered to occur when prices rise in an all-round way, in contrast to changes, and it continues.
September 15, 10 The consumer price CPI announced by the National Bureau of Statistics in August increased by 2.0% year-on-year, but the ex-factory price PPI announced at the same time decreased by 5.9% year-on-year, which exceeded expectations and hit a six-year low. There is no doubt that the 42nd month is in a negative growth range. The difference between CPI and PPI reached 7.9 percentage points, the largest difference since 1994. The deviation between CPI and PPI tests the wisdom of macro-control. A basic judgment of the industry is that the deflation risk faced by China's economy is greater than the inflation risk, and it needs monetary and other regulatory measures to continue to relax. And the central bank and other departments have also stated that they will not affect the judgment of the overall price level because of the price trend of a single commodity.

Consumer price index measures the average change of retail prices of more than 200 kinds of goods and services over a period of time. These more than 200 kinds of goods and services are divided into 8 categories. When calculating the consumer price index, each category has a weight that can show its importance. These weights are determined by investigating the products and services purchased by thousands of families and individuals. The weights are revised every two years to make them conform to people's changing preferences.
