当专利许可对企业至关重要时,专利政策如何影响创新?为了解决这个问题,本研究将创新者和追随者之间的自愿专利许可,如在文献中讨论的产业组织,到一个动态的一般均衡模型。与以往的研究不同,许可费和被许可人的数量都是由创新者的最大化和自由进入条件内生决定的。使用这个模型,我们表明,强有力的专利保护并不总是促进创新,经济增长和福利。此外,扩展的分析提供了政策含义,专利政策的效果取决于如何困难进一步创新是没有专利许可的当前领先技术。
How does patent policy affect innovation when patent licensing is crucial for firms? To address this question, the present study incorporates voluntary patent licensing between an innovator and followers, as discussed in the literature of industrial organization, into a dynamic general equilibrium model. Unlike previous studies, both the licensing fee and the number of licensees are endogenously determined by the innovator’s maximization and the free-entry condition. Using this model, we show that strong patent protection does not always enhance innovation, economic growth, and welfare. Furthermore, the extended analysis provides the policy implication that the effect of patent policy depends on how difficult further innovation is without patent licensing of the current leading technology.
