International licensing and quality‐enhancing technology spillover in a product cycle model
研究国际质量提升技术溢出对南北国家产业分布和创新的影响，发现更强的溢出效应抑制了北方创新研发和南方适应性研发，损害双方福利，质疑了技术溢出为正外部性的普遍观点。
Abstract This paper examines the effects of an international quality‐enhancing technology spillover on the international industry distribution and innovation in a dynamic North‐South model. When a Southern firm receives a technology transfer from the North through international licensing, the technology spills over to other Southern firms by enhancing the quality of their products. We find that a stronger spillover effect depresses both Northern innovative R&D and Southern adaptive R&D, and thus is welfare‐impairing both for the advanced country and recipient country. The results cast doubt on the common view that regards the technology spillover as a positive externality.
