First, people
PPI is an indicator to measure the trend and degree of ex-factory price changes of industrial enterprises, an important economic indicator to reflect the price changes in the production field in a certain period, and an important basis for formulating relevant economic policies and national economic accounting. At present, there are more than 4,000 PPI survey products in China (including more than 9,500 specifications), covering all 39 industrial categories, involving 186 survey categories.
Second, PML
PMI is a comprehensive economic monitoring index system released every month, which is divided into manufacturing PMI and service PMI, and some countries have established construction PMI. At present, more than 20 countries around the world have established PMI systems, and the world manufacturing and service PMI has been established. PMI is an index summarized through the monthly survey of purchasing managers, which reflects the changing trend of the economy. PMI has five characteristics. First of all, it is timely and leading. Because the survey method is quick and simple, it is much earlier than other official data.
Producer price index (PPI) is an index used to measure the average change of manufacturers' ex-factory prices, and it is one of several price indexes collected and sorted by statistical departments.
What are the main terms of 1.PPL?
The main purpose of producer price index is to measure the price changes of various commodities at different production stages. Generally speaking, the production of goods is divided into three stages: the original stage: the goods have not been processed; Intermediate stage: the goods need further processing; Completion stage: goods will not be processed at this time.
Second, comprehensiveness and guidance.
PMI is a comprehensive index system, covering many aspects of economic activities. Its comprehensive index reflects the overall economic situation and the overall trend of change, while the indicators reflect all aspects of enterprise supply and procurement activities. Third, authenticity and reliability. The PMI questionnaire survey is aimed at purchasing and supply managers, and the original data obtained will not be modified. After summing up, using scientific methods for statistics and calculation ensures the authenticity of data sources. Fourth, it is scientific and reasonable. According to the contribution rate of each industry to GDP, determine the sample proportion of each industry, and consider the geographical distribution and different types of enterprises to determine the sample.
Third, it is simple and easy to operate.
After the PMI is calculated, it can be compared with last month. If the PMI is greater than 50%, it means that the economy is rising, and vice versa. Generally speaking, the aggregate composite index of manufacturing industry is higher than 50%, which means that the whole manufacturing economy is growing, and lower than 50% means that the manufacturing economy is declining. PMI index system is of great significance to the economic forecast and business analysis of government departments, financial institutions, investment companies and enterprises. First of all, it is an important basis for government supervision, financial institutions and investment companies to make decisions. This is a leading indicator. According to the analysis of American experts, PMI index is highly correlated with GDP, and its inflection point is often several months ahead of GDP. In the past 40 years, the peak of manufacturing PMI in the United States can be more than half a year earlier than the business climax and several months earlier than the business downturn. In addition, it can also be used to analyze industrial information. According to the relationship between industry and GDP, we can analyze the development trends and changes of various industries.
