Since 200 1, China has adopted the international practice to compile and publish the consumer price index based on the price level in 2000 every month as the main index reflecting the degree of inflation (or deflation) in China. With the approval of the State Council, the Urban Dispatching Corps of the National Bureau of Statistics is responsible for the compilation and related work of the national consumer price index, and organizes, guides and manages the consumer price survey and statistics of all provinces, autonomous regions and municipalities.
The commodity and service items compiled by China's price index are determined according to the composition data of consumption expenditure of nearly 1 100 urban and rural households and relevant regulations. At present, * * includes eight categories, including food, alcohol and tobacco, clothing, household equipment and services, medical care and personal goods, transportation and communication, entertainment and education, cultural goods and services, and residence, with 25 1 basic categories. The consumer price index is based on the price survey of nearly 30,000 price points in 550 sample cities and counties in China, and is calculated according to the process and formula of international norms.
CPI =(pt 1q 0 1+pt2q 02+…+PtmQ0m)/(p 0 1q 0 1+p02q 02+…+P0mQ0m)* 100
Where P \u commodity price;
Q____ Quantity of goods;
M- type of goods;
T- current cycle;
0—— base period.
In the formula, the denominator represents the total expenditure of residents on related commodities in the base period to be compared; Molecules say that residents are right about the current situation in the current period
Price: the total expenditure for purchasing the same kind and quantity of goods.
Simplify the above formula in words as follows:
CPI= total expenditure on commodities purchased in the current period/total expenditure on commodities purchased in the base period * 100 (commodities are of the same category and related to the sample).
