| With the continuous development of China’s oil industry,the competition and cooperation relationship is gradually changing,due to the scarcity of resources.In order to pursue group rationality and the maximization of organizational benefits,the competition and cooperation relationship has already get rid of the relationship of perfect competition.And it has been proved that this kind of idea transformation is helpful to the improvement of enterprise benefit.The essence of enterprise strategy is a kind of game.As a part of enterprise strategy,there is a natural connection between the choice of enterprise competitive strategy and game theory.This article will briefly analyze how do oil companies choose the competitive strategy from the perspective of game theory.As the important strategic analysis tools,game theory will provide guidance for the enterprise strategic decision.Based on the actual competitive situation of the three oil giant,this paper establish models that price and sales are decision variables.The enterprises obtain advantage through Nash equilibrium achieved by constantly game.The game model is established from two aspects.One is between enterprises and users,namely is the way that oil product pricing.It explains how to use the price consistency model to keep the price of the whole industry at a high level,and then eliminate the price competition among enterprises.Another one is the competition and cooperation game model for enterprise development projects.Competition for projects is common in all walks of life.Although the oil industry is special,it is not exempt from vulgarity.Even so,in the face of domestic and foreign largescale development projects,companies cannot fight alone due to the huge scale of the project and the limitations of technology and resources of each company.Therefore,enterprises choose to use cooperation to maximize their own interests.Finally,the article returns to the most basic analysis of game matrix and uses the method of eliminating inferior strategy or dominant strategy to obtain the unique Nash equilibrium,so as to make a clearer and clearer judgment on how the enterprise chooses to game in terms of competitive strategy.Based on the understanding of the development and competitive situation of oil enterprises,this paper analyzes the choice of competitive strategy of Chinese petroleum enterprises.The corresponding conclusion is obtained through the construction and solution of the models.From a perspective of game theory,the optimal strategy combination obtained by the model is consistent with the actual situation.Competition not only reduces sales,but also has a big impact on their own earnings.The game models of the above two aspects validate this view.Therefore,the enterprise should use the existing game model to analyze and choose the competitive strategy.It is necessary for enterprises to improve the overall efficiency.On account of the above conclusions,some existing problems and countermeasures are put forward in chapter 5 of this paper.It is hoped that the research of this paper can be used to guide the selection of enterprise competitive strategy,and hoped that the paper can bring new ideas to the strategic decision of enterprises. |
