The development of ecommerce has greatly boosted the connection between small farmers in China and the large market. The present study found that ecommerce enables smallholder farmers to enter the global value chain by reducing their transaction costs for information, thus facilitating their entry into the market. Logistics and communication infrastructure, inclusive digital business platforms for smallholder farmers, and a new generation of farmers are prerequisites for developing rural ecommerce. To develop, rural ecommerce needs an ecosystem suitable for the participation of smallholder farmers, composed of network operators, government, and service providers. Network operators are the main force in the development of ecommerce. The government, facilitating ecommerce development, is responsible for infrastructure construction. Service providers offer a set of public services. In addition, ecommerce may exclude small farmers who cannot participate in the digital economy or lack the required skills. Therefore, it is necessary to be alert to the inequality between regions and between farmers caused by the digital gap.
