Belt commerce is based on shopping centers or shopping malls, and it is promoted by connecting the shops in the shopping malls in series to form chain commerce. "Belt" represents the corridor between shopping malls, connecting all the shops inside, and connecting the shops into a whole just like a belt connecting pants. Through this business model, shops in shopping malls can enjoy passenger flow and marketing resources, reduce the risk of free operation of shops, provide consumers with rich shopping choices, and increase the attractiveness and competitiveness of shopping malls.
