本文构建了一个扩展的南北产品周期模型，其中北方创新、FDI和南方自主创新都是内生变量。研究发现，严格的南方知识产权保护对北方创新、FDI和南方创新都产生负面激励，降低南方自主创新企业份额，减少北方直接投资，不利于南方经济发展。本文扩展了不包含FDI的产品周期模型，并讨论了质量领导者创新和有效跟随者创新的差异。研究发现，南方知识产权保护对创新的负效应是稳健的。无论是否存在FDI、质量领导者是否存在成本优势，南方知识产权保护导致北方和南方创新率都下降，并且导致经济中模仿企业的比重上升。

This article develops a North -South product cycle model with endogenous Northern innovation, FDI, and Southern indigenous innovation. We find that a strengthen of intellectual property rights （IPRs） protection in South discourages Northern innovation,FDI,and Southern indigenous innovation,lowers the measure of Southern innovation production and the rate of production transfer,curtails Southern economy development. We extend our analysis to productcycle models without FDI,and discuss innovation by quality leaders and by followers separately. Our result shows that south IPRs protection discourages innovation is robust. Whether or not there is FDI, whether or not followers conduct innovation, tighter Southern IPRs protection always decreases the rate of Northern and Southern innovation, and increases the measure of imitation production.
