Research on Game Strategy between Node Enterprises in Thermal Coal Supply Network

摘要

The main purpose of this paper is to study the relationship between the costs and profits of coal enterprises and coal-fired power plants based on the game strategy under different factors. By analyzing the status quo of coal supply nodes, the article analyzes the game of coal supply enterprises in the state of cooperation and non-cooperation, and analyzes the quantum game of coal enterprises and coal-fired power plants in two cases. The first is that one adopts the traditional game strategy and the other uses the quantum game strategy. The second is both of them using quantum game strategy. Finally, it is concluded that the increase of electricity price, the reduction of other costs of power enterprises and the reduction of the cost of coal enterprises will lead to the increase of cooperative profits between coal enterprise and coal-fired power plants in the coordination game. Secondly, the decision-making among firms has nothing to do with the Nash equilibrium in the non-cooperative game. Thirdly, the enterprises that use the quantum game will earn more profit.
