A Game Study On Trade Competition And Alliance Under International Oligo

At the present, there has a profound transform in the domain of the international economics; incomplete competition, vertical specialization and intra-industry trade have changed the patterns of international competition among the firms. Based on the information transfer, the strategic interaction among the export firms in international market has been obviously strengthened; a sequential multiplayer game has been formed between the government, the firms and consumers in different countries. The research of the paper applies the methods of game theory to analyze the economic phenomenon include the motivation, the cause of formation and the path of development, and seek the detailed condition and realized the path of the efficient equilibrium in international trade, all these researches have important theoretic and policy value for the firms and governments in the evolutionary pattern of trade confliction and cooperation. At the same time, the paper strives to absorb and develop the latest achievements of the domestic and overseas about the trade competition and alliance, then extend the theoretic and method system of the trade competition and alliance for our country, and incorporate the latest achievement of the game theory into the research of the trade competition and alliance. The paper is constituted by five parts, and not only discusses the basic principles in the whole but highlights some basic problems existing in the research as well; on the other hand, the paper extends some theories based on the other's research and put forward some independent thought and model. The paper include the main content as following: (1) The Competition Model and Extension Under The Free Trade In the researching of this part, the paper introduces the static and dynamic trade competition model under the symmetric and asymmetric information at first, and considers the Cournot-Nash equilibrium, perfect sub-game equilibrium, and Bayes-Nash equilibrium without the policy intervene. These basic models and propositions establish the theoretic basis for further analysis and comparison. On the basis of the given research framework, the paper focuses on the problem of signal delivery under incomplete information, the paper doesn't limit in the research of signal efficiency of the trade policy, but delivery the information of the firm cost through strategic choice of the trade competitor and realize the efficient equilibrium accepted by all parities in international market. In this paper, the FDI and export trade...
