中文摘要：

博弈论在市场竞争分析中具有广泛的应用,通过构建基于二次运输函数的市场竞争模型,运用博弈论方法研究产品市场竞争情况.放松厂商定位的约束条件,市场竞争的空间扩大了.结果表明,当市场中两垄断厂商定位不局限于消费者分布的线性空间时,市场环境加剧了厂商之间的竞争,但厂商博弈的均衡仍然存在.该模型是研究网络环境下产品市场竞争策略的有效方法.

英文摘要：

Game theory widely used in the analysis of market competition. The market com- petition is studied using the game method through establishing the market competition model based on the quadratic transport function. Loosing position constraints of the manufacturers, the market competition space has increased. The result has showed the market environment has intensified the competition between manufacturers when the market position of the two monopoly manufacturers is not limited to the linear distribution space of consumers, but the game equilibrium has still existed. The model is an effective method to study the market competition strategy of the product under the network environment.
