中文摘要：

在具有网络效应的市场中，企业往往采取自愿性创新披露的策略，这与传统的观点背道而驰。为此，建立了一个网络效应下的两阶段古诺竞争模型，研究市场的网络外部性强度、竞争者的产品可替代程度和企业的创新程度对企业自愿性创新披露的影响。研究结果表明，网络外部性强度和竞争者产品可替代程度对企业自愿性创新披露程度具有正向影响，创新程度对企业自愿性创新披露程度具有负向影响。企业的创新披露决策是在综合权衡以上因素所带来的成本和收益之后所作的理性选择。并根据上述研究结论，为企业管理者提出了一系列的管理启示，同时指出了研究的局限性和未来的研究方向。

英文摘要：

Contrary to conventional viewpoints, firms often adopt the strategy of voluntary innovation disclosure in markets with network effects. In order to solve this puzzle, this article builds a two-stage Coumot competition model by considering network effects and analyzes the impact of network externalities, product substitutability and degree of novelty on finns＇ voluntary innovation disclosure. The result indicates that network externalities and prod- uct substitutability are positively related to degree of firms＇ voluntary innovation disclosure while degree of novel- ty is negatively related to it. The rational decision on voluntary disclosure is essentially made by evaluating the benefit and cost of the above three factors. According to the result, this article gives some management implica- tion for practitioners. In the end, limitations on the study are summarized and future directions are suggested.
