Course Introduction:Let’s first take a look at what is year-on-year and month-on-month: Year-on-year: usually refers to the comparison between the nth month of this year and the nth month of last year. The year-on-year development rate is mainly to eliminate the impact of seasonal changes and to illustrate the relative development rate achieved by comparing the development level of this period with the development level of the same period last year. Period-on-month: usually refers to the ratio of changes in volume within two consecutive unit periods (such as two consecutive months). There are two types of chain ratio: chain growth rate and chain development speed. So how to calculate the year-on-year growth rate and the month-on-month growth rate: Year-on-year growth rate: Year-on-year growth rate = (number of the current period − number of the same period) / number of the same period * 100% Chain growth rate: Chain growth rate = (number of the current period − number of the previous period) )/Previous period
