The year-on-year growth rate generally refers to the growth rate compared with the same period last year. Year-on-year growth rate (range) compared with the previous period, year or history. The development speed can be divided into year-on-year development speed, ring-on-ring development speed and fixed-base development speed due to different base periods. Expressed as a percentage or multiple.

The growth in the same period refers to the comparison of the same subject, the same period in the same year, but different years.

Difference:

1, the same subject is compared in different periods, that is to say, the same subject is compared in different periods.

2. The objects of comparison are different, and different objects are compared at the same time. The same period refers to the comparison of different subjects in the same period.

3. With the different extension, year-on-year growth can be divided into year-on-year development speed, chain-on-chain development speed and fixed-base development speed. Expressed as a percentage or multiple.

Calculation formula of year-on-year growth rate:

The ratio of a certain indicator in the same period = (the value of an indicator in the current year-the value of the indicator in the same period last year)/the value of the indicator in the same period last year.

Namely: year-on-year growth rate = (index value of the current year-value of the same period last year) ÷ value of the same period last year * 100%.

Formula for calculating the month-on-month growth (decline) rate in this period:

According to the needs of wholesale market price analysis, the ring ratio can be divided into daily ring ratio, weekly ring ratio, monthly ring ratio and annual ring ratio.

The month-on-month growth (decrease) rate in this period (%) = [(current price/previous price)-1]* 100%.

Description:

(1) If the calculated value is positive (+), it is called growth rate; If the calculated value is negative (-), it is called decline rate.

(2) If the current period refers to the current day, this week, the current month and this year, the previous period refers to yesterday, last week, last month and last year.
