Abstract

As the development of the economic, the competitions were becoming much more intense among the enterprises. More and more enterprises tried to entry into new industry, which could upgrade their business ability. What is more, the external enterprises might gain more profit and they could also open up wide profile margins. But some external enterprises often had forecast deviation when they entered into the new industry, which was because of entry opportunities, their own ability aim and the environment. Because of that, many enterprises could not entry into the new industry in time. In base on this, the paper indicated that the phenomenon of entry among the supply chains, which was based on the theory of Bain. The enterprises of the supply chain tried to entry into the internal supply chain to gain more profile. Beside that, the enterprises could also promote their market competitiveness. Because the enterprises of the internal supply chain had efficient operation characteristic, wide customer groups and stable profile income. But the supply chain was a system, whose operation was complex, changeable and regularity. If the external enterprises wanted to inter into the internal, they should have many games with the internal enterprises of the supply chain. So the external enterprises could find suitable way to entry into the supply chain. Specially, based on the research background, purpose, meaning and the theory of the industry entry, this paper have a analysis from three aspects which was with the manufactures as the example:Firstly, this paper analyze the efficient operate characters of the internal enterprises of the supply chain, which includes the efficient information sharing, high-quality logistic service capability and the paperless operation. Beside that, the paper analyze the advantages of the external enterprises either, which includes receiving information timely and accurate, having their own loyal customer, increasing their operational efficiency of the business. These advantages are the reasons to entry into the internal supply chain for the external enterprises. What is more, the paper analyzes the boycott of the influencing factors, such as economies of scale, different production and the absolute cost advantage, which contains the barriers when the external enterprise enter into the supply chain.Secondly, the paper analyzes the one-game model among the manufactures of the supply chain. In the model, this paper uses the price-sensitive demand function, and considering the optical market-clearing price and the market sharing affection. Based on this, the paper determines the demand function of the manufactures of the supply chain. Beside that, the paper calculates the best profile and the best sales price with cournot game method. In addition, the paper also analyzes the reasons of the entry when the external enterprises inter into the supply chain. In based of this, the paper improve the model with the compact coefficient, and then analyze the reasons that the internal enterprises would easy the boycott when the external enterprises entry into the supply chain.Finally, considering the bounded rationality of the manufactures, the paper introduces punishment mechanism and additional revenue into the model. In based on the contract game model, this paper builds the evolutionary game matrix with the way of evolutionary game theory. According the evolutionary game matrix, the paper solves the evolution of the dynamic equation and the evolution of the equilibrium point. At the same time, this paper also analyzes the evolutionary stable strategy in different situations. The result will be good for the internal and external manufactures of the supply chain to make better strategy, and this paper will have guiding significance for the internal and external manufactures which would achieve the long-term stability.
