Based on the Internet of Things (Iot) technology and transaction cost theory, this paper constructs the contract model of agricultural products sharing, and studies the coordination degree of stakeholders in agricultural products supply chain under the two-level revenue sharing contract model. This paper also analyzes the willingness of the participants to adopt the digital reform and the main factors influencing the adoption of digital technology. The results show that in the agricultural product supply chain, the decentralized decision-making of participants results in the decrease of supply chain performance and the deviation of individual and collective interests of participants The application of digital technology such as Internet of Things (Iot) in agricultural products has the problems of high cost and low efficiency, which reduces the participants’ willingness to use. A case study of Litchi, honey Pomelo, sweet potato and other special agricultural products in Zhangzhou, Fujian Province was conducted to demonstrate the impact of cost and efficiency on technology adoption. On this basis, relative policies and suggestions are put forward to provide strong support for the popularization of digital technology and the transformation of agricultural digitization.
