【摘要】：我们讨论在双寡头垄断的市场环境下,两家厂商竞争的两期模型。市场上的消费者对每家厂商商品的需求量是两家厂商销售价格的函数。每个厂商在期初制定关于生产量,销售价格的决策。与以往文章不同的是,我们考虑学习效应对其生产成本的影响,假设他们的第二期单位生产成本随着他们第一期生产量的增大而降低。假设两家厂商了解市场上消费者的需求函数,并在每期同时制定关于价格和生产量的决策。他们的决策目标是最大化其两期利润之和。我们建立数学模型,求解他们的纳什均衡,给出厂商每期的最优销售价格,最优生产量和最优利润。在第三章中,我们对这个模型进行拓展延伸,引入两个供应商,考虑供应链存在的情形。假设两家厂商同时向两个供应商订货,组装制造产品后向消费者销售。每个供应商同时向两家厂商销售原材料,且他们第二期的单位生产成本受到第一期销售量的影响,从而会影响其第二期销售给制造商的批发价格。我们由此可以分析两家制造厂商第一期的订货量对于他自身和其对手的决策的交互影响。
[Abstract]:We discussed in the duopoly market environment, two models of competition. The two companies on the market of consumer goods for each vendor demand is a function of the two companies sales price. Each manufacturer set at the beginning of the period on production volume, sales price decision. Different from the previous paper, we consider the learning effect the influence on the production cost, the assumption of their second unit cost of production decreases with increasing production period. They first assume that two firms to understand the market consumer demand function, and at the same time in each formulation about the price and production decisions. Their decision objectives is to maximize its profit and we two. The establishment of mathematical model, the Nash equilibrium solution of them, to the manufacturers in each of the optimal selling price, the optimal production quantity and optimal profit. In the third chapter, we carry on this model Extension, the introduction of two suppliers, considering the supply chain situation. At the same time to assume that two manufacturers two suppliers, assembling products after sales to consumers. At the same time, the two companies to each supplier sales of raw materials, and their second unit production cost by the first phase of sales, which will affect the second period sales to the manufacturer's wholesale price. Thus we can analyze the interaction effect of the two manufacturers in the first phase of the orders for his own and his opponent's decision.
