Research On The Cooperative Game Theory And It's Applications

Game theory, which is the complication of economics and the social sciences as a whole that is extremely important in a theoretical curriculum, which uses mathematical tools to analyse various socio-economic phenomenon of strict criterion, acquired a fruitful research results. Which is one important economics analysis, in the economics and the whole scientific community it is extremely important in a theoretical discipline, which uses mathematics to conduct in-depth analysis of the economy, clear the economic theory of the object of study and analysis technology, game theory's object is between people, companies and mutual interests between the companies under the constraints of the strategy choices and their corresponding actions may result. 50s in the late 20th century, the main applications of game theory on economics began beam up. In the 1960s, game theory, mathematical economics and economic established a solid and lasting ties. Since the 1980s the game theory and application progressed to be a mature theory. Game theory itself has grown up to be a relatively perfect and rich in content, theoretical system.However the non-cooperative game theory in theoretical study and practical applications are to hold a dominant position.Compared to the non-cooperative game theory, cooperative game is very imperfect. Cooperative Game's three basic problems still have not been completely resolved: The solutions of game of cooperation, and it's stability, cooperation game mechanism for the formation of the solution. However, it is a powerful tool to describe human society, with further research.the development of the network will become an important way bidding system. Therefore, we have reason to believe that cooperative game theory research in the future will inevitably highlight its unique nature on bidding systems, increasingly play a strong role. To the applications, the domestic have been progressed some studies, mostly concentrated on the Shapley value of the simple applications. From the game structure, cooperative game can be divided into two cooperative game and more cooperative game, also known as the former two bargaining issues, Nash bargaining solution of a balanced solution is the most famous one. The latter is also known as the Union game, the main solution of the nuclear method represented the dominant method and the representative of the valuation method of Shapley value. The dominant methods seldom use because of their deficiencies, the Shapley value because of its existence and uniqueness and the calculation method of standardization and the reasonableness of the distribution methods have been widely applied.In the two-person cooperative game, this paper discusses an S-K solution, such as the advantages and disadvantages of the game will be more cooperation in the Shapley contribution to the solution of the distribution of thinking by the introduction of two game participants, received a S-K optimized solution, the solution make all participants in the share of proceeds to be allocate shares proportionally with their contributions to the union's. We introduced alliance game theory's solutions'existence and stabilities, introduced a game's nuclear and the concept of Shapley value, and introduced the concept of the progressed Shapley value, the progressed Shapley value is an improved method of the Shapley value to improve the Shapley value method in the actual sense of the distribution of benefits more equitable, because the progressed Shapley value methods ruled out a feasible set'impacts on other independent feasible sets. The original Shapley value method can not discern feasible sets'interventions in Shapley's calculations. Based on the current largest provider of online advertising auctions, Google company's analysis of the auction models in the online auction business. Google company's online advertising bidding method is take out by the introduction of price discrimination, to stop the unnecessary competitions and blindly null biddings. This will not only increase the rate of successful advertising biddings, but also firms who want to make advertisings can save many costs.According to the iResearch survey, datas show that in 2006 China's Internet Marketing size of the market is 60 billion yuan, up 4.17 billion yuan in 2005 increased by 44 percent. According to iResearch the research and forecasting, in 2007 China's Internet marketing will reach 8.3 billion yuan, up 38 percent growth in 2006; China's network marketing will continue to maintain high-speed development to the year 2010, the scale of China's Internet marketing is expected to reach 23 billion till then. Online auction is accompanied by the advent of the electronic information age bornrecently. Internet auction have the conveniences of using the internet at the same time, let the buyer and seller in online auction platform set get the simultaneous transaction, the buyer in the auction network have more commodity options, the seller will attract customers use the online auction crowd. For such a big domestic market network, this paper used the improved Shapley value solution method to make a empirical analysis, it associate the experiences of google company's online auction strategys, concluded that we should learn from the google method . In this paper, in order to improve the Shapley value of the theoretical basis, and identify how the google company price their network ad, I make my advance on our country's online auction: we should create a guild to guide the net auction providers and it's bidders according to China's immature market, the lack of absolute industry leading enterprises in China online auction market, so the message's exchanges between network service providers, and between bidders, service providers and bidders will be much better, and the distribution of interests will be more fair. Through the development of effective strictions, the providers of Internet advertising industry should establish a stable alliance, which will dominant Chinese online auction shares considering the method of Shapley solution.
