And the additional income was related to the investment in introducing blockchain traceability technology. The game model of pricing strategy was established based on the consumer’s cognition of commodity information. Comparing and analysing the game results before and after introducing blockchain traceability technology was an effective way to explore the income mechanism of secondary supply chain enterprises. The results show the following. Investing in supply chain and introducing blockchain traceability technology could effectively improve the consumer’s cognition of commodity information. Further, this could increase the optimal market demand of commodities and the optimal income of wholesalers and retailers.
