A2A rural e-commerce is an early e-commerce model and a trade cooperation relationship between agents. The whole process of commodity trading depends on the services of agents, and the participants generally include platform enterprises, information workers, sellers and buyers, such as the blue sky model in Quanzhou. Under the Lantian model, Lantian Group Company, as a platform, is responsible for the construction and operation of e-commerce platform, which is the core role of the whole supply chain and determines the efficiency of supply chain operation. The information officer or agent is responsible for releasing transaction information and matching transactions, and the role is agricultural product supplier or agricultural material supplier. Agents connect upstream sellers and downstream buyers to provide intermediary services. Generally, sellers are small rural enterprises, which are connected with farmers, cooperatives and other agricultural producers and are responsible for the unified acquisition of agricultural products. Downstream supermarkets, wholesale markets and other buyers directly sell to end consumers or the next level of terminal sales.
