How does the global e-commerce system work?

E-commerce, literally, is the use of various electronic tools for business activities. These tools range from basic telegrams, telephones, broadcasts, televisions and faxes to computers and computer networks to modern systems such as NII (National Information Infrastructure-Information Superhighway), GII (Global Information Infrastructure) and the Internet. Commercial activities are all activities based on the demand activities of pan-commodities (physical and non-physical, commodity and non-commodity production factors, etc.). ) to the reasonable and legal consumption of pan-commodities except the typical production process. In a narrow sense, it refers to the use of the Internet to engage in business or activities. E-commerce platform is a platform website established for e-commerce activities, which is divided into B2B, B2C and C2C according to the transaction objects of e-commerce. As for the operation mode of e-commerce, it is generally like this: register on the platform (free or charged), then upload the product information for promotion, get the order, organize the delivery (sign the contract if it is a large enterprise), and wait for the buyer to receive the goods (if it is an international buyer, the transaction mode may be different) to complete the payment. In fact, the operating mode of B2B is very different from B2C and C2C.
