本文在综合考虑网络外部性与专利创新程度的条件下，对创新者不许可策略、固定许可策略与变动许可策略进行了分析，在此基础之上，确定了创新者的最优专利许可策略。研究表明，当网络外部性较弱时，变动许可是创新者的最优许可策略；当网络外部性较强时，固定许可是创新者的最优许可策略；当网络外部性强度适中时，如果创新程度较低，创新者将选择变动许可策略，如果创新程度较高，创新者将选择固定许可策略。本文的研究为理解与制定专利许可策略提供了新的思考。

Considering network externalities and degree of innovation, patent licensing strategies, such as no licensing, fix-fee licensing, and royalty licensing are explored, then the innovator’s optimal licensing strategy is analyzed. It is found that with weak network externalities, royalty licensing strategy is optimal; with strong network externalities, fixed-fee licensing strategy is optimal; when the network externalities are moderate, with low degree of technological innovation, royalty licensing strategy is optimal, and with high degree of technological innovation, the fixed-fee licensing strategy is optimal. New insights for the decisions on patent licensing strategies are given.
