Indicators commonly used in Western countries to calculate and reflect the speed of industrial development
Industrial production indexJust useWeighted arithmetic meanThe physical quantity index of industrial products compiled by Western countries is commonly used to calculate and reflect the speed of industrial developmentindexIt is also the preferred indicator for business analysis.Industrial production indexIt is a relative indicator, measuringmanufacturing industryThe real output of mining and public utilities is measured on the basis of quantity rather than amount.The index reflects the prosperity and development trend of industrial economy in a certain period.As with other relative indicatorsIndustrial production indexAttention must be paid to the comparability of data, which must be the same asAbsolute indexOnly when used together can we explain the problem objectively and comprehensively.
Industrial production indexindustrial production index。First name.Use singular number.An index compiled according to the total industrial production of a country or region in a specific period of time, consisting of machine manufacturing, mining and public utilities.U.S.AOfIndustrial production indexIt is counted by the Federal Reserve and published once a month.This includes industrial andminingOutput value is important for analyzing and judging the investment marketEconomic indicators。The other is: index of industrial production;industrial output index；industrial production
withU.S.AFor example,Industrial production indexfromFederal Reserve Board(Federal Reserve Board) collects data, and its quoted data are actual production data, most of which are estimated data (because it is difficult to collect data).The sample is 250 individual enterprises representing 27 different industries, with 1987 asbase period。There are three different categories of content:
★ All industries;
★ Market classification:includeFinal product, Chinese products and raw materials market;
★ Industrial category:includemanufacturing industry(durable goods and non durable goods), mining and public utilities.
U.S.AThe statistical results of the previous month will be published on the 15th of each month.indexThe rise represents the improvement of the economy. The interest rate may be raised, which should be biased against the US dollarLidoAnd vice versaBliss。

According to the aboveIndustrial production indexThe principle of, due toWeightThere are three different calculation formulas for different forms:
★ O represents the product output (subscript 1 is the reporting period, 0 isbase period；The same below)
★ W is the weight;
★ P is the unit product value.

calculationIndustrial production indexThe overall plan of mainly includes the determination of representative products,WeightThere are three steps for the calculation of
1. Determine the product catalog of the representative at this level. This is the calculationIndustrial production indexIs an important link of.Whether the selection of representative products is scientific and reasonable directly affectsProduction indexAccuracy of calculation results.China has selected more than 500 representative products every month. The basic principles of selection mainly include: selecting representative products according to varieties and specifications in various industries, and paying attention toValueRelatively large, rising trend, long economic life, and relatively stable products in a certain period of time.
2. Collect weightbase periodCalculate and determine the weight of relevant basic data in.calculationWeightThe basic data of mainly includes the prices of representative products, unit product added value, and industriestotal output valueAnd added value, representative productsbase periodAnnual output, etc.
Initial weight in Chinabase periodIt was fixed in 1995 and remained unchanged for five years.It can be said that to establish a set of weights is to prepareIndustrial production indexThe most difficult work.
3. Reported on behalf of the productIndividual index, and use their ownWeightThe weighted average calculates the sub index (industry index) andTotal index。
The calculation principle is different.Industrial production indexThe calculation principle is the product method, and the latter is the factory method.Industrial production indexIt is calculated by selecting important representative products andIndividual indexComprehensive industrial development speed calculated by weighted average;The latter is calculated by using all industrial productsReporting periodThe total output value of industrial enterprises andbase periodCompared with the output value.
★ It conforms to international practices, can be in line with international standards, and can be directly used for comparison of international statistical data;
★ It can better meet the timeliness requirements;
★ It helps to improve the anti-interference ability of data and improve the data quality of industrial development speed;
★ It can provide the development speed of different industries and better avoid the cross industry phenomenon;
★ It can meet the needs of the new national economic accounting system.
3. It should be noted that,Industrial production indexIt is a relative indicator. It only reflects the prosperity and development trend of the short-term economy. When the research speed andbenefitIn case of problems, the absolute quantity index cannot be provided;At the same time, it cannot provide the development speed grouped by enterprise logo, and these data still need to be obtained through other ways.
