한국의 산업유형별 기술 지식 흐름에 관한 연구 : Pavitt의 분류에 따른 산업간 특허 인용 분석을 중심으로

This paper examines the flow of technological knowledge in South Korea during the era of technological hegemony, using Pavitt's taxonomy and patent citation analysis. It employs text mining and word cloud analysis to assess the current industry types in Korea based on patents. The study confirms Pavitt's assertion that in Korea, the flow of knowledge in science-based and specialized supplier industries is crucial for innovation initiation. However, it identifies two new knowledge flow patterns, differing from Pavitt's model. These are attributed to the diversification of customer values and the enhanced inter-industry knowledge exchange facilitated by Information and Communication Technology (ICT) advancements like AI, Big Data, and IoT, within the Fourth Industrial Revolution framework. The findings suggest a need for increased focus on research and investment in science-based and specialized supplier industries in Korea. Additionally, with growing technological knowledge interaction among the four industry types, policy efforts should be directed toward fostering collaboration and knowledge sharing.
