企業對企業的電子商務（Business To Business）

Business-to-business (B2B) is a term commonly used to describe commerce transactions between businesses, as opposed to those between businesses and other groups, such as business-to-consumers (B2C) or business-to-government (B2G). More specifically, B2B is often used to describe an activity, such as B2B marketing, or B2B sales, that occurs between businesses and other businesses.
The volume of B2B transactions is much higher than the volume of B2C transactions. The primary reason for this is that in a typical supply chain there will be many B2B transactions involving subcomponent or raw materials, and only one B2C transaction, specifically sale of the finished product to the end customer. For example, an automobile manufacturer makes several B2B transactions such as buying tires, glass for windshields, and rubber hoses for its vehicles. The final transaction, a finished vehicle sold to the consumer, is a single (B2C) transaction.
