Abstract: The aim of this paper is to analyze the adoption factors of the internet of things (IOT) in agricultural products traceability systems considering the context that multiple risk factors interaction. Firstly, this paper systematically analyzes the adoption factors for the IOT in agricultural-products traceability systems based on the coupling perspective of TOE model and UTAUT theory. Then, the indexes system is constructed and a method based on DEMATEL is employed to identify adoption factors. Finally, the critical adoption factors are determined by calculating centrality degree and cause degree. The result shows that the critical adoption factors for IOT in agricultural products traceability systems are government support, technology compatibility, social impact and support of enterprise senior.
