Study On Spatial Competition Decision Of Mixed Oligopoly Under Spatial Price Discrimination

Since the 1980s,the mixed oligarchy theory has gradually become one of the main frameworks for the study of state-owned economy in domestic and foreign economic circles.The mixed oligopolistic market has a wide range of realistic backgrounds.In China,this market is particularly in line with some industries in which China's state-owned economy is relatively concentrated,such as electricity,telecommunications,oil,steel,and automobiles.In recent years,the problem of "spatial competition" between state-owned enterprises and private enterprises in mixed oligopoly market structure has become one of the hot topics in industrial organization theory.The existing literature mainly focuses on the cost structure,market structure and decision-making order of mixed oligopoly spatial competition.On the other hand,it is less involved in the context of space price discrimination.For some industries with large transportation costs or markets with differentiated products,space price discrimination is "ubiquitous".More importantly,most of the existing literature studies the spatial competition of mixed oligopoly under Nash equilibrium conditions.Considering the spatial competition between enterprises in real life,the behavioral decision of enterprises will be changed by their competitors' behavioral decisions.The impact,the correctness of the guess directly affects the decision-making behavior of the enterprise.In order to maximize the goal,the enterprise needs to achieve the consistency of the conjecture as much as possible,that is,the consistency conjecture.The introduction of consistency conjecture makes industrial organization theory more realistic in describing and dealing with economic problems.Therefore,based on the existing research,this paper investigates the mixed oligopoly competition decision based on the principle of consistency conjecture in the context of spatial price discrimination,and further explores the existing literature.This paper is divided into six parts,which are introduction,literature review,spatial selection decision equilibrium analysis of mixed oligopoly under linear production cost,spatial location decision equilibrium analysis of mixed oligopoly under convex production cost,and mixed oligarch under linear production cost.The spatial location decision equilibrium analysis and conclusions and future research prospects.The research shows that:(1)Under the linear production cost,the spatial competition decision of the mixed oligopoly under the condition of consistency conjecture is equivalent to the spatial competition decision under the Nash equilibrium condition.(2)Under the convex production cost,compared with the results under the linear production cost conditions,the convex production cost under the condition of consistency conjecture makes the enterprises closer to each other,at which time the social welfare will decrease and the profits of the private enterprise will increase.Compared with the Nash equilibrium,social welfare has improved and private companies have increased profits.(3)Under the linear production cost,when a foreign private enterprise is introduced to participate in space competition,different market structures will have certain influence on the spatial location decision and welfare effect of mixed multi-dimensional,compared with Nash equilibrium,social welfare and Private companies may have equal profits and may or may not be able to improve.(4)When the production cost of the enterprise is linear,as long as the foreign private enterprise is not adjacent to the domestic private enterprise,the final market structure will lead to the equivalence conjecture and the Nash equilibrium result equivalent if there is competition from foreign private enterprises.
