Research On Energy Model And Stability Of Enterprises-farmers Symbiotic System For Fresh Agricultural Products

As the fountainhead of fresh agricultural products supply chain,farmers have the characteristics of lacking of funds,small scale of production,scattered regions,poor storage capacity and low marketing position.As the core node of supply chain,enterprises also concrete lots of characteristics,such as abundant funds,large scale of production,centralized factory land and leading marketing position.Enterprises and farmers interact with each other and finally form a symbiotic system.Because of the characteristics of fresh agricultural products,the symbiotic system is weak and unstable,leading the lack of value-added space on supply chain,which restricts the transformation of the industry.This paper applies symbiosis theory to research on the symbiotic system and stability of the system,which holds on the practical significance and value.Based on symbiotic theory,this paper defines the symbiotic relationship between Enterprises and farmers,analyzes the intrinsic motivation of the symbiotic relationship,defines the symbiotic system of the fresh agricultural product.This paper also designs the symbiotic unit model,the symbiotic model,the symbiotic energy model and the symbiotic environmental model according to the principle of symbiotic system.Among them,the symbiotic energy model is divided into symbiotic unit model and new-added energy model.Firstly,by defining the ecological footprint of farmers' input and the enterprise labor force,the symbiotic unit energy model is established by the evaluation method of ecological carrying capacity.Secondly,the paper established the new-added energy model by taking account to three qualitative parameters,the long-term symbiosis intention and the intensity of interaction,including the interests of the enterprises and the farmers.Finally,The stability analysis of the symbiotic system is carried out by taking the Lyapunov method and the Matlab numerical simulation method,and the symbiotic model is determined by the positive and negative analysis of the symbiotic parameters b,g.The simulation results show that the results of the simulation experiment are in agreement with the theoretical derivation.Comparing with the parasitic model,the mutual symbiotic model can make the two symbiotic units have the largest symbiotic energy.It can also prolong the convergence rate of the symbiotic system,and make the symbiotic system stable,and achieve the optimal economic output index.In conclusion,the results provide a theoretical basis for the selection of cooperative relations between the enterprises and farmers of fresh agricultural products,and also provide a reference path to obtain more long-term interests of the symbiotic relationship.
