synonymYear on year growth(Theorem) Generally refers to year-on-year growth rate
Year on year growth rate, usually abbreviated as YoY+% in the report, generally refers to the year-on-year growth rategrowth rate。The year-on-year growth rate compared with that of the previous period, year or history.Development speedDue to different base periods, it can be divided into year-on-year development speedChain comparison development speedandDevelopment speed of fixed base。AllpercentageOr multiple.
Of an indicatorContemporaneous ratio=(Value of an indicator in the current year - value of this indicator in the same period of last year)/value of this indicator in the same period of last year
That is, year-on-year growth rate=(Indicator value-Value in the same period of last year) ÷ Value in the same period of last year * 100%
according towholesale marketFor price analysis, the month on month ratio is divided into day on month, week on week, month on month and year on year.
Index X for judging the current month on month growth (decline) rate (%)=[（current prices /Price of last period) - 1] * 100%
Note: (1) If the calculated value X is a positive value (+), it is calledgrowth rate；If the calculated value X isnegative(-) is called the decline rate.
(2) If the current period refers to the current day, the current week, the current month and the current year, the previous period refers to yesterday, last week, last month and last year.
（2） Calculation formula of year-on-year growth (decline) rate of the current period
Year on year growth (decrease) rate of the current period (%)=[(price of the current period/price of the same period last year) - 1] * 100%
Note: (1) If the calculated value is positive (+), it is called the growth rate;If the calculated value is negative (-), it is called the descent rate.
(2) If the current period refers to the current day, the current week and the current month, the same period of the previous year refers to the same day, the same week and the same month of the previous year.
Difference between year-on-year growth rate and growth rate
Note: (1) Year on year growth rate means growth rate, which means growth rate in another way.
(2) When calculating year-on-year growth rate, there is a specific time limit. Unlike growth rate, which has a wide range and broad definition, year-on-year growth rate generally refers to the growth rate compared with the same period of last year.

The year-on-year growth rate is mainly to eliminateSeasonal variationThe impact of the current periodDevelopment levelThe relative development speed compared with the same period last year.For example, February of the current period is compared with February of the previous year, and June of the current period is compared with June of the previous year.
hisCalculation formulaIt is: year-on-year development rate=(current development level/development level in the same period of last year - 1) * 100%. In practical work, this indicator is often used. For example, the development rate calculated by comparing a year, quarter, month with the same period of last year is the year-on-year development rate.

Ring ratioIt is divided into day on month, week on week, month on month and year on year.
Chain comparison development speedYesReporting periodComparison between the level and the level of the previous period (comparison of adjacent periods)Dynamic relative number。It indicates the development and change degree of the phenomenon stage by stage.For example, the comparison between each month in a year and the previous month is calculated, that is, February is more than January, March is more than February, April is more than March... December is more than November, indicating the degree of development month by month.
Fixed base ratio

Fixed base ratioDevelopment speedAlso called total speed, it isReporting periodThe ratio of the level to the level in a fixed period indicates the overall development speed of this phenomenon in a longer period.For example, during the Ninth Five Year Plan period, the level of each year is compared with that of 1995, and the level of each month in a year is compared with that of December of the previous yearDevelopment speed of fixed base。
