Abstract: his paper explored the relationship between firms 'R&D and the government patent protection under the spatial price discrimination model. The empirical results showed that the higher degree of patent protection would motivate the firms R&D decision. There was inverted U-shaped relationship between firms'R&D and patent protection. From the view of social welfare and innovation, the patent protection had a critical turning point, which changed with the social and industrial R&D environment and transaction.
摘要: 本文使用空间价格歧视模型,分析了企业研发决策与政府专利保护之间的关系。结果不仅证明了企业在专利保护程度较高、研发环境较好时会进行研发,研发数量与政府的专利保护呈倒U型关系,而且发现,企业研发后,在专利保护程度极低和极高时,企业会采用特许权方式对外专利授权,中间状态下企业不对外授权。从社会福利和社会创新的角度来看,专利保护不是越多越好,而是存在一个临界的拐点。该拐点随着社会研发环境和行业交易费用的增加而递增。
