The producer price index (PPI) is an index that measures the trend and degree of change in the ex-factory products of industrial enterprises, and is an important economic indicator reflecting the changes in the production field in a certain period, and is also an important basis for formulating relevant economic policies and national accounts.
The Producer Price Index (PPI), unlike the CPI, is primarily intended to measure the total cost of a basket of goods and services purchased by a firm. Since firms ultimately have to pass on their costs to consumers in the form of higher consumption, changes in the producer price index are generally considered useful for judging changes in the consumer price index.
