Research on the Reasons for the Decline in Sales Growth of the E-commerce Shopping Festival Amid the COVID-19 Pandemic Based on Grey Prediction Model Constructed by Python

Under the impact of technology and the pandemic COVID-19, the net economy has developed rapidly, especially in e-commerce. The development of e-commerce has greatly facilitated people’s lives, especially during the epidemic. But the growth rate of e-commerce sales during shopping festivals in the first half of this year dropped significantly. To analyze the reasons for this decline in the growth rate of the net economy and to predict whether there is a possibility of a decline in the sales of the e-commerce shopping festival in the second half of the year, we selected the household storage data of Guangdong Province in the last four months to construct a grey prediction model. The data analysis results show that residents’ willingness to store keeps rising every month and will continue to increase in the next two months. And the sales of the e-commerce shopping festival in the second half of the year will decrease yearly. Aiming at this problem, we suggest that the promotions of merchants should be simpler to stimulate consumers’ purchase desire.
