全球创新版图中的后发城市：知识产权、全球治理与发展中国家的技术赶超

How do latecomer cities rise in a global innovation landscape that is increasingly concentrated, networked, and governed across borders? Drawing on massive geocoded patent, scientific publication, and trademark data analyzed with AI and network methods, this talk addresses the question at three levels. At the global level, it maps half a century of shifting innovation geography—identifying global innovation clusters, tracing the evolving trajectories of the world’s science and technology hub cities, and revealing the structure of global innovation networks—and examines the changing direction of innovation toward sustainability, including global R&D trends, climate adaptation, and methane abatement, with implications for climate and innovation policy. At the city level, a WIPO development study of Shenzhen shows how a latecomer city evolved from imitation to frontier innovation within global innovation networks, distilling governance lessons for technological catch-up in the developing world—including the case for a “patient government” that provides long-term, stable support for local science. The talk concludes with the emerging potential of trademark big data for measuring product and service innovation and industrial upgrading, and its implications for intellectual property and global governance.
