The 48-hour Internet access rate of AliExpress is an indicator that measures the proportion of Internet users who access the Internet within 48 hours. It is often used to assess the Internet penetration rate and the degree of user dependence on the Internet. This indicator is calculated by dividing the number of users who successfully access the Internet within a specific time period (such as 48 hours) by the total number of users who may access the Internet within that time period. This ratio can be used to understand the popularity of the Internet among the target user group and the degree of user dependence on the Internet. Generally speaking, the higher the 48-hour Internet access rate, the higher the Internet penetration in the region or group, and the stronger the user's dependence on the Internet. This indicator can also be used to assess the differences in Internet usage between different regions or groups, and for the formulation and evaluation of Internet development policies.
