Any firm in the oligopolistic market must consider different strategies that the rivals take while it makes its production and sales decisions .The past researches of oligopolistic market often stress on how the firms interact and seek for solution from market equilibrium. There are also many traditional analytical models concerning about oligopolistic market ,but these models were based on the hypothesis of fully symmetric information under duopoly ,it is not fully suitable of our economic market .The thriving of game theory progresses the content of firm theory in oligopolistic market and application in the market economic.
However, the crucial element of game theory ----the profit function , which a firm decides its price and quantity of the product ---is hard to determine .Therefore , we will pay more attention on studying the gray theory construction and gray estimation of profit function in order to take off the hypothesis regarding we need to know the marker demand function and rival’s cost when estimating the function of return .Then try to find out a feasible strategy of foreseeing the economic market development in domestic oligopolistic market.
Grey Model(1,n) consider all the system variables, and its purpose is to discuss the system factors X1、X2、X3….Xn relate to the dynamic relationship with X1. So gray model has the similar character with oligopolistic market. Therefore, we use the gray model to construct the oligopolistic market model to predict the profit function.
