Quantum Game Equilibrium Analysis Of Coopetition Supply Chain Coordination Mechanism

With the development of information globalization and information technology modernization,the adjustment of competition between enterprises and the dynamic integration of resources have a far-reaching impact on improving enterprise performance.In order to survive and develop in the fierce competition,enterprises often need to break through the limitations of their own technical capabilities and resources,and explore and make full use of market opportunities by establishing cooperative relations with other enterprises through external forces.However,the conflict of individual interests makes the cooperative relationship between enterprises have to be accompanied by competition,and there are significant differences in the degree of competition and cooperation at different stages,which is essentially an evolving "coopetition".The academic community has conducted a lot of research on this coopetition relationship,but due to the intricate interaction and role of enterprise members,especially the dynamic changes of coopetition relationship,it is worth further in-depth discussion and research.Therefore,this thesis applies quantum game theory and method to study the cooperative production problem of competitive enterprises based on key components through mathematical modeling,aiming to prove the influence of quantum entanglement mechanism on the establishment of rational individual cooperative stability,in order to provide new methods for strategic choices for enterprises in different market positions,and provide a new research idea for achieving "win-win" for enterprises.The main research contents and methods of this thesis are as follows:(1)Taking manufacturers with independent product production capacity as the research object,the competition and cooperation supply chain formed around key components was analyzed under the condition of considering the market competition of end products.The profit function of manufacturers is constructed by using the principle of revenue maximization,and the game relationship between competition and cooperative behavior of manufacturers and the decision-making problems of various parameters are analyzed and discussed in depth.(2)The combination models of four competing strategies of manufacturers in wholesale competition and license competition were constructed,the changes of quantum entanglement and its impact on revenue and balance were analyzed,the possibility and stability of cooperation formation were explored,and then the choice of competition strategy by manufacturers from the perspective of revenue stream risk was studied.(3)The game model of manufacturer competition and manufacturer competition is quantized,and the optimal solution of Nash equilibrium and quantum game equilibrium of classical games is obtained by using quantum entanglement to simulate the entanglement of interests in the coopetition relationship,and the influence of different entanglement conditions on each decision parameter and the optimal strategy of manufacturers is compared,and the influence of important factors on the game result is verified by numerical simulation.The results show that the analysis paradigm of introducing manufacturer competition and cooperation into quantum games,after considering the entanglement of states,the party actively seeking cooperation no longer has to bear the risk of "betrayal",which solves the "prisoner’s dilemma" problem in classical games to a certain extent.Manufacturers without cost advantage should improve their product innovation,try to distinguish from the products of manufacturers with cost advantages in the competitive market,to prevent them from using cost advantages to carry out price wars with themselves,the higher the degree of substitution of products on both sides,the more unfavorable the manufacturers without cost advantages,in addition,appropriately enhance the degree of "entanglement" with enterprises with cost advantages,can reduce the gap between balanced output and balanced benefits.For enterprises with cost advantages,the best quantum strategy is to sign wholesale cooperation contracts with competitors in the market,using wholesale prices as a means to influence the decision-making behavior of enterprises without cost advantages.
