Study of the Long-Term and the Short-Term Product Solutions of Dynamical Cournot Model with Durable Goods
耐用品动态古诺模型的长期产量解和短期产量解研究

Taking into account of the property that the market capacity for the durable goods changes in time,in this paper,a modified dynamical Cournot model with two firms' simultaneous-move game in the case of only two game stages is presented.Then,two kinds of produce solution when the firms pursue the long-term profits and short-term profits are obtained,respectively.With the comparison and analysis of these solutions,it can be illustrated that the product solution of long-term profit is superior to that of short-term profit.On base of this,a new game model which respectively considers the short-term and short-term profit as the firms' choice of strategy is established,and the result indicated that the two firms will be in the prisoner's dilemma and so have to pursue the short-term profit.
