Abstract: In order to achieve new quality productivity in agriculture and promote the high-quality development of the agricultural product supply chain, a theoretical analysis framework of agriculture+new quality productivity was constructed. Based on the current situation of the fresh agricultural product in China, an analysis was conducted, and it was concluded that the current agricultural product supply chain was facing the practical dilemma of ‘being unable to sell in rural areas and unable to buy in cities’. Therefore, blockchain technology was introduced to build a new fresh agricultural product supply chain service platform. Based on functions such as distributed ledger, big data, and consensus mechanism, the coordinated development of all parties in the supply chain was ensured by breaking down information barriers between various entities, adjusting the information flow mode of the supply chain, providing one click services, information traceability mechanism, and data sharing mechanism, and balancing the origin market and end market.

Key words: new quality productivity, blockchain, fresh agricultural product, theoretical model
