From catching up to industrial leadership: towards an integrated market-technology perspective. An application of semantic patent-to-patent similarity in the wind and EV sector
研究提出一个整合市场与技术的框架，利用自然语言处理分析专利语义相似度，比较中国、日本、韩国在风电和电动汽车领域的追赶轨迹与潜在陷阱。
Abstract Studies on catching up and industrial leadership have often used market-related variables to evaluate the catch-up trajectories of latecomer countries and firms. In this study, we aim to enhance our understanding of these concepts by presenting an integrated market-technology framework. Using natural language processing techniques allows us to go beyond patent numbers and analyze patent novelty and impact as well as technological changes over time. In empirical case studies on wind energy and electric vehicles in China, Japan, and South Korea, we compare and identify country and sector-specific catch-up trajectories and potential catch-up traps.
