Abstract:One of the core elements to enhance the resilience of the modern food industry chain is to lead enterprises to establish an integrated set of standards. To this end, it is necessary to solve the problems of difficulty in identifying key common technologies with dissemination and competitiveness and difficulty in connecting standards used by stakeholders in various links in the industry chain. Initially, an HMM-HITS Topic Keyness Identification Model was constructed based on the LDA topic clustering model, and characterized by the identification of key technologies which were not only competitive but also had strong dissemination power. Combined with the theme commonality identification model based on common skewness, a key commonality technology identification model was constructed. For the key common technologies identified by this model, based on the principles of value, rarity, difficulty in imitating, irreplaceability and inevitable implementation, the key common technologies that can enter the standard system list of leading enterprises were identified. Subsequently, based on the agricultural product supply chain mechanism, a standard connection consultation mechanism with the goal of improving resilience was built.. Finally, the standard complex formulation and optimization process for the modern grain industry chain was derived, which was verified in the formulation of the japonica rice standard complex.
