摘　　要：在具有网络外部性特征的产业中,产品的兼容性已经不再是纯粹的技术层面的问题,而是企业的竞争战略问题。着重研究在位厂商与新进入厂商的兼容性战略决策问题。通过产品之间的兼容度将消费者的转移成本内生化,得到了新进入厂商兼容性决策的临界点,且该临界点与网络外部性强度负向相关。当新进入厂商可获得的与在位厂商产品相兼容的兼容度水平位于该临界点左侧区域时,采取拒绝与在位厂商兼容的策略是最优的;反之,则采取兼容策略,从而新进入厂商可以借助在位厂商的安装基础迅速发展。Compatibility is the important feature of network economics and turns out to be a strategic issue in industries exhibiting network externalities. In this paper we study new entry firms＇ compatibility decisions in a horizontal differentiation model with network externalities. A critical point of compatibility decisions, which increases as the strength degree of network externalities decreases, is obtained. When the degree of compatibility is less than the critical point, the entry firm will not take compatibility decisions. Otherwise, the entry firm will chose compatibility decisions to enjoy the installed base of incumbent firm.
