The Output Competition for Color TV Supply Chain Based on Game Theory

This paper researches and compares the questions of the output competition and cooperation of the manufacturers between two color TV supply chains under the Cournot and Stackelberg game models. By studying we succeeded in finding the scope of the output cooperation distribution coefficient being required by both sides of the game for realizing the outputs cooperation. Further more, we extend the two models to infinitely repeated game which is more in line with the reality, and we get the conditions of the refined equilibrium results of the cooperative output. Simultaneously, we establish the relation between the discount factor and the output distribution coefficient, and the results indicate that the collusion outputs of both sides can bring down the outputs and increase the prices, profits of both sides and the total profits of the two supply chains.
