And annulus compared the difference is that because of the difference of both use base period, the connotation of its reflect is completely different.

When we analyze the trend of data in our work, we usually use year-on-year and month-on-month comparisons, so what is the difference between year-on-year and month-on-month, let’s take a look together.

Details

01

The year-on-year ratio is usually the first month of the year compared to the last month. The year-over-year rate of development is primarily intended to eliminate the effects of seasonal changes and to illustrate the relative rate of development achieved in the current period in comparison with the year-over-year level of development.

02

The calculation formula is: the formula of year-on-year development rate should be changed to: year-on-year development rate=development level of the current period/level of the same period last year × 100%； Year on year growth rate=(current development level – the same period last year)/the same period last year × 100%。

03

Ring ratio, which represents the change ratio of quantities in 2 consecutive reference periods (such as two consecutive months). Chain growth rate = (current period number – previous period number)/previous period number × 100%. Reflect the increase of the current period compared with the previous period; the speed of development on a month-on-month basis generally refers to the ratio of the level of the reporting period to the level of the previous period, indicating the speed of development of the phenomenon period by period.

04

The so-called ring analysis, as far as the annual report is concerned, is to compare the performance data of the second half of the year with the performance data of the first half of the year. Among them, the performance data for the second half of the year can be obtained by subtracting the number of medium periods from the annual number. Divide the number of medium periods and multiply it by 100% to obtain the ratio or range of increase or decrease in the reporting period.

05

To put it simply, the year-on-year, month on month and fixed base ratio can be expressed in percentage or multiple. The fixed base ratio development speed, also referred to as the total speed, generally refers to the ratio of the level in the reporting period to the level in a fixed period, indicating the overall development speed of this phenomenon in a longer period. Year-on-year development speed, generally refers to the current development level and the same period of last year development level comparison, and reached the relative development speed. The month-on-month development speed generally refers to the ratio of the level of the reporting period and the level of the previous period, indicating that the development speed of the phenomenon is period by period. Year-on-year and quarter-on-quarter, although both reflect the speed of change, but because of the different base period, their reflected connotations are completely different; Generally speaking, the sequential can be compared with the sequential, but can not be compared with the year-on-year comparison; For the same place, considering the reflection of the development trend in the vertical direction of time, it is often necessary to compare the year-on-year and the month-on-month comparisons.
