通过将纵向差异引入到二次函数运输成本下的Hotelling模型中，研究具有不同质量、网络外部性、兼容性和转移成本的2个垄断厂商的竞争策略。首先，进行选址；然后，进行价格竞争的完全信息动态博弈，得到产品具有横向差异和纵向差异的2个垄断厂商市场竞争的均衡策略，推广了Hotelling模型的结论；最后，在选择横向差异最大化的情况下，分析了一般市场竞争策略，在无纵向差异条件下分别讨论了不同网络效用系数、兼容性和转移成本对市场竞争策略的影响。
通過將縱嚮差異引入到二次函數運輸成本下的Hotelling模型中，研究具有不同質量、網絡外部性、兼容性和轉移成本的2箇壟斷廠商的競爭策略。首先，進行選阯；然後，進行價格競爭的完全信息動態博弈，得到產品具有橫嚮差異和縱嚮差異的2箇壟斷廠商市場競爭的均衡策略，推廣瞭Hotelling模型的結論；最後，在選擇橫嚮差異最大化的情況下，分析瞭一般市場競爭策略，在無縱嚮差異條件下分彆討論瞭不同網絡效用繫數、兼容性和轉移成本對市場競爭策略的影響。

The strategies /of two duopoly firms, which are characterized by different quality, network externality coefficient, compatibility, switch costs, were studied after Hotelling model with longitudinal product differentiation and quadratic transport costs was introduced. For two firms, their locations and, competitive in price were chose simultaneously. Equilibrium market strategies of duopoly firms with Horizontal and longitudinal product differentiation are obtained, so, Hotelling model is extended. Under the assumption that duopoly firms would choose their maximal horizontal product differentiation, The influence of differentiation products quality, network externality coefficient, compatibility coefficient and switch costs on the duopoly＇ competition equilibrium was analyzed.
