There are three differences:

The nature of the platform is different. The international version of Amazon is a global online retailer, a big data company, a cloud computing and cloud solutions company, etc. The domestic e-commerce platform is just a simple e-commerce shopping platform.

The consumer markets they face are different. For Chinese sellers, Amazon is an export cross-border e-commerce platform. In layman's terms, it is to sell products made in China to overseas markets and be able to have direct contact with overseas end consumers; while the domestic e-commerce platform faces the domestic consumer market.

The concept of the store is different. The Amazon platform emphasizes product-centricity and does not have the concept of a store.
