累积性创新、知识产权保护策略与最优政策

摘要

建立了一个两阶段研发(R&D)竞赛模型，分析在累积性创新市场上厂商选择不同知识产权保护策略对其创新决策及最优政策的影响。研究表明：当商业秘密能够作为创新的有效保护机制时，政府应该对初始创新实行宽专利保护政策，以刺激创新信息的披露；如果此时专利政策仍不能奏效，那么政府就应该实行宽松的反垄断政策，允许初始创新者和后续创新者达成同盟协议。%Built a two stages of development (R&D)race model,analysis of the impact of firms in the cumulative innova-tion market on different intellectual property protection strategies on the innovation decision and optimal policy.Research shows that,when the trade secret can be used as the effective protection of innovation mechanism,the government should implement a wide patent protection policy to the initial innovation,to stimulate the innovation of information disclosure.If the patent policy still does not work,so the government should be looser antitrust policy,allowing the initial innovator and subsequent innovators alliance to reach agreement.
