Agricultural e-commerce
China currently has more than 30,000 agricultural e-commerce platforms nationwide, of which there are 3,000 agricultural e-commerce platforms. E-commerce of agricultural products must establish a good shopping experience with customers in order to usher in continuous consumption power and drive related consumer groups.
Target group positioning is the primary consideration for agricultural product e-commerce platforms. If the target group is positioned at the elderly who basically cannot access the Internet or people with low spending power, it will obviously face a loss. In addition, due to the particularity of agricultural products, the delivery requires refrigerated and frozen hybrid delivery vehicles, as well as refrigerated turnover boxes and constant temperature equipment. Otherwise, no matter how good the original quality of the product is, the customer will receive the goods with quality problems. Therefore, the cost of logistics distribution will become the biggest problem for testing agricultural product e-commerce platforms
Cai Yudong, deputy director of the Department of Electronic Commerce of the Ministry of Commerce, said recently that my country’s agricultural products online transactions are currently facing many difficulties, such as the overall market size is not concentrated, infrastructure construction is not perfect, and laws and regulations are not yet complete.

Improve the system and standardize the development order. Accelerate the establishment of e-commerce laws and regulations, standardize services such as information release, online transactions, credit services, electronic payment, logistics distribution, and dispute handling, and combat commercial fraud, sales of fake and shoddy products, publishing false and illegal advertisements, and unfair competition in accordance with the law.
