The full name of PMI index in English is Purchasing Managers Index, which means Purchasing Managers Index in Chinese. It is an index summarized through the monthly survey of purchasing managers, which can reflect the changing trend of the economy.
Manufacturing PMI. The system originated in the United States in the 1930s. After decades of development, it now includes business activity indicators such as new orders, output, employees, supplier distribution, inventory, price, backlog orders, new export orders and imports.
The above indicators are synthesized according to the data obtained from the monthly questionnaire survey of purchasing managers of sample enterprises, and then the five categories of indicators such as production, new orders, employees, supplier distribution and inventory are weighted to obtain the manufacturing PMI comprehensive index.
Extended data:
PMI survey data comes from the judgment of the purchasing manager of the enterprise according to the business situation, and there is a logical correlation between the indicators of the business operation. Theoretically, if the purchasing manager fills in the questionnaire carefully, his answers to different questions should reflect the operating conditions of the enterprise.
The PMI business reports of manufacturing and non-manufacturing industries were released on June 1 day and March 3, respectively, which were much earlier than the statistical reports of other government departments, and the selected indicators were ahead, so PMI became a timely and reliable leading indicator for monitoring economic operation.
