CPI is an important macroeconomic indicator reflecting the changes in the price level of consumer goods and services related to residents' lives, and it is also an important indicator for macroeconomic analysis and decision-making and national economic accounting. Generally speaking, the level of CPI directly affects the introduction and intensity of national macro-control measures, such as whether the central bank adjusts interest rates and deposit reserve ratio. At the same time, the level of CPI also indirectly affects the changes of capital markets (such as stock market, futures market, capital market and financial market).
The purpose of compiling consumer price index is to understand the basic situation of price changes all over the country, analyze and study the impact of price changes on social economy and residents' life, meet the needs of governments at all levels to formulate policies and plans and carry out macro-control, and provide reference and basis for national economic accounting.
The combination of consumer price index (CPI) and employment situation report (non-agricultural) has become another hot economic indicator that has been carefully studied in the financial market, because inflation affects everyone, it determines the cost of consumers to buy goods and services, affects the operating costs of enterprises, greatly damages the investment of individuals or enterprises, and affects the quality of life of retirees. Moreover, the prospect of inflation is conducive to the establishment of labor contracts and the formulation of government fiscal policies.
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.
