As is illustrated in the chart, the number of online stores run by college students is roughly 4 million in 2017, approximately 5 million in 2018 and around 6 million in 2019. This has resulted a notable increase in the number of people employed in this trade, up from almost 12 million in 2017 to nearly 20 million in 2019. Apparently, the number of college students’ E-commerce has been on a dramatic rise over the past few years.
What accounts for the increase? From my perspective, at least three factors contribute to the change. To begin with, the change is closely related to the rising income of the Chinese people. More importantly, the change has a lot to do with the turning of the college students’ attitude towards and outlook on career development. Finally, the change is enhanced and promoted by the government’s bettering policies as well as the more convenient channels in the E-commerce field.   
With the development of society, the rising trend is bound to continue for a couple of years in the future. As far as I am concerned, it’s a positive trend and should be encouraged since it is beneficial not merely to college students but to the whole society.
