New farmers play a crucial role in enriching the forms of agricultural industry, leading farmers to get rich and promoting the integration of industry and village. To address the problems such as unbalanced input-output and unstable cooperative relations between the government and new farmers, an evolutionary game model of government and new farmer was constructs to study the evolutionary path of strategy selection between the two sides, and the factors affecting the decision-making of both sides by using numerical simulation were analyzed. The results show that the evolutionary stability strategy is influenced by costs, additional benefits, indirect losses and subsidies. The higher the costs, the faster the evolution of behavioral strategies into non-participation to assist in rural revitalization. The increase of additional gains, indirect losses and subsidies contributes to supporting rural revitalization of both sides, when one party participates in rural revitalization while the other party does not, the behavior of the participating one will be invalid.

It focuses on enhancing the overall efficiency of blockchain traceability, constructing the blockchain security guarantee system, and improving the blockchain privacy protection technology. Through the above research, the technical innovation direction is offered for China’s agricultural product supply chain traceability, the continuous maturation of blockchain technology and its application are promoted, and innovative thoughts are provided for improving the coordinated development level of China’s agricultural product supply chain, the efficiency of agricultural product quality and safety management, and the quality of agricultural product supply chain traceability.

In order to provide references and suggestions for the future development and improvement of public health emergency management policies, the existing public health emergency management related policy texts in a multi-dimensional way was analyzed, and text mining was conducted on the policy texts related to public health emergency management issued at the national level in China from 2003 to 2023, and typical policy samples were selected to construct a PMC index evaluation model for public health emergency management policies. The evaluation system of PMC index model consists of 10 first-level variables and 38 second-level variables, and there exist 3 grades of policies as a whole, 1 qualified policy, 10 good policies, and 4 excellent policies. At this stage, the emergency management policy system for public health emergencies is basically perfect, but it still needs to be continuously optimized and improved in the future. It is recommended to reasonably divide the policy time limit, build a multifaceted and coordinated emergency management mechanism, and accurately implement policies in order to realize the all-round and precise management of public health emergency management.

Taking the nine library and reading space projects in the fourth batch of national public cultural service system demonstration projects as examples, grounded theory was used to code and analyze 42 case materials of the nine projects, and a mechanism model was constructed for the innovative development of libraries and reading spaces. It id found that the innovative development path of libraries and reading spaces includes aspects such as demand management, facility services, personnel services, resource activities and management operations. Among them, demand management innovation is the logical starting point, which plays a guiding role in optimizing service supply, while management and operation innovation provides comprehensive guarantees for service supply innovation. On this basis, countermeasures and suggestions are proposed for the innovative development of libraries and reading spaces from the aspects of demand inquiry and response, precise service supply, and management and operation guarantee.
