What kind of service does it belong to, such as trading consultation, exchanging information, comparing prices and product features?

B2B: Business-to-business e-commerce, that is, enterprises exchange products, services and information through the Internet. The e-commerce transaction mode of China Manufacturing Network belongs to B2B mode, which is divided into vertical B2B and horizontal B2B, and vertical B2B is upstream and downstream. Manufacturers or commercial retailers can form a supply relationship with upstream suppliers. For example, Dell Computer Company cooperates with upstream chip and motherboard manufacturers in this way. Manufacturers can form sales relationships with downstream distributors, such as transactions between Cisco and its distributors. Horizontal B2B, which concentrates similar transaction processes in different industries in one place, provides trading opportunities for buyers and suppliers of enterprises, such as Alibaba and China Manufacturing Network. In fact, this kind of website is neither an enterprise with products nor a merchant dealing in goods. It just provides a platform to match sellers and buyers online, and buyers can find information about sellers and goods online.
