内容简介：
This paper examines the trade-off between market power and access to advanced technologies in the context of patent protection policy in developing economies.  I exploit a policy shock in China that unevenly strengthened patent enforcement across provinces, combining it with a novel dataset that links Chinese firm-level production data to multinational firms' global patent portfolios.  I find that stronger patent protection incentivizes multinationals to adopt their best technologies in Chinese affiliates and encourages domestic inventors to produce higher-quality innovations. However, both groups also raise their markups.  To rationalize and quantify these findings, I develop a multi-product model where inventors endogenously reduce markups but withhold higher-quality products due to concerns over local imitation.  Enhanced patent enforcement drives out imitators, incentivizing inventors to adopt superior products while raising markups across their portfolios.  The calibrated model reveals an inverted U-shaped relationship between patent protection and aggregate welfare, with strong heterogeneity across industries.

演讲人简介：
陈维立，宾夕法尼亚州立大学经济学博士候选人，研究领域涵盖国际贸易、企业创新与产业政策，主要通过实证和定量分析，探讨企业在全球化背景下如何调整技术以应对政策变化。当前研究聚焦于以下两个主题：（1）发展中国家的专利保护政策如何在市场势力与技术获取之间寻求平衡；（2）贸易政策如何通过影响企业创新的技术路径，进而塑造国家间的技术相互依赖性及全球福利。
