The profit model of Amazon in the United States refers to the fact that for a long time after the company was founded, Amazon has been pursuing a self-operated model. It builds its own warehouses and logistics and sells its own products.

This model can certainly guarantee product quality, but its disadvantage is also obvious, that is, the cost will remain high.

Since the service systems supporting retail, such as warehousing and logistics, have strong economies of scale, expanding the scale and increasing the number of users are the most effective ways to reduce the average cost of goods.

In this context, while Amazon is operating its own business, it gradually introduces other manufacturers on the platform and uses the number of users generated by these manufacturers to obtain economies of scale.
