摘要
在具有网络外部性的Hotelling模型中,放松厂商定位必须局限于消费者空间的假设,运用Sackelberg博弈来研究产品具有不同边际成本结构的企业竞争策略。相比较于传统的Nash博弈价格均衡结果,当不局限厂商定位空间时,两厂商通过Sackelberg价格博弈可以选择更大的产品差异性。如果边际成本相等,两厂商在Stackelberg博弈均衡中都获得比在Nash博弈均衡中更大的市场利润,当不局限厂商定位空间时,市场先进入者获得先动优势,当局限厂商定位空间时,市场后动者获得后动优势。
In Hotelling model with network externality, relaxing the restriction that the firms must be located in consumer space, competitive strategy duopoly enterprises with different cost is researched by Stackelberg equilibrium. Comparing with the result by traditional Nash equilibrium, both firms without restriction location get more product differentiation by Stackelberg equilibrium. When marginal cost is equal, both firms obtain more market profit by Stackelberg equilibrium than that of by Nash equilibrium, the market leader is dominant without restriction location and the market follower is dominant with restriction location.
