摘要本文构建了一个扩展的南北产品周期模型,其中北方创新、模仿和外商直接投资都是内生变量。本文研究发现,严格知识产权保护是有利于南方(发展中国家)还是有利于北方(发达国家),依赖于北方创新性质导致的市场结构。在垂直创新的寡头市场,严格知识产权保护对南北双方都造成伤害。在水平创新的垄断竞争市场,适度的知识产权保护对南北双方都有利。我们的研究发现,南方存在一个不同于北方的最优知识产权保护强度,南方不需要实施与北方一样严格的知识产权保护标准。 We develop an extended North-South Product cycle model in which North innovation, South imitation, and Foreign Direct Investment （FDI） are all endogenous. Our model predicts whether tighter Intellectual Property Rights （IPRs） benefit the North or South depends crucially on market structure. Under oligopoly due to vertical innovation, tighter IPRs hurts both regions. Under monopolistic competition due to horizontal innovation, tighter IPRs benefits both in the long run if here exists an appropriate degree of IPRs protection. We find that there exists an optimal degree of IPRs protection in the South, which may differentiate from that in the North.
