Producer price index (PPI) is used to measure the price of products that producers need to buy in the production process. So this index contains the price information of raw materials, semi-finished products and final products (about 3,000 kinds of things are used in the United States) in three production stages.

Possible factors leading to PPI increase
1. Domestic supply-side structural reforms continued to advance. Judging from the internal structure of PPI, the rise of PPI is actually a structural increase. The increase in PPI in August mainly came from production materials, and the growth rate of living materials was relatively stable.
2. Changes in international commodity prices have an impact. According to the data of relevant international organizations, from August 2065438 to August 2007, the prices of many upstream products rose, which was mainly caused by the recent sustained recovery of the world economy, the steady expansion of market demand and the expansion of raw material demand in China.
