| 摘 要： | R&D/产品问题的文献,都无一例外地在模型中采用了数量竞争(产量作为决策变量)的形式;而现实中市场往往以产品的价格作为第一操作变量进行竞争,或采取更为剧烈的“价格战”。从价格竞争的Cournot均衡模型出发,对模型中的变量进行替换得到产量竞争模型的形式,在这一变换中,并不改变竞争各方非对称的产品替代性和竞争优势,表明这种形式上的转化并没有使原来的产业特性在转变中发生相对改变。进一步对模型中的产品替代性进行讨论,可以说明Bertrand式的价格竞争也可以映射一种数量竞争。

| Abstract: | The literatures on R&D/Product apply the format of quantity competition(product output to be the decisional variable),while in reality the price of product always used to be the first decisional variable,and drastic price competition is not sparse.Starting with Cournot equilibrium model of price competition,the authors replace variables in the model and reach the format of quantity competition model.During transformation the asymmetric product substitution sequence and relative competition advantage keep unchanged.With further discussion of product substitution,we conclude that Bertrand format price competition can map a kind of quantity competition. |
