The key factors of agricultural retailers the adopt blockchain technology had been discovered, including strengthening the government's promotion of blockchain technology, increasing the cultivation of blockchain and supply chain technical talents and attracting interdisciplinary talents who master blockchain technology and other technologies, increasing policy support, and developing information technology related to blockchain, etc.
