Abstract

This study analyzed the formation and change of Korea’s patent technology transaction network between 2001 and 2020, a period following the enactment of the Act on the Promotion of Technology Transfer and Commercialization. Using patent assignment records, intercity networks were constructed in five-year intervals and analyzed using Exponential Random Graph Models(ERGMs). Network link density is initially low but rises steadily, while mutuality and preferential attachment intensify, whereas transitivity and multiple paths exert only limited influence. The network is anchored by large cities with abundant research infrastructure, and both geographic and technological proximity significantly increase the likelihood of a transaction. These findings indicate that, despite quantitative growth, patent technology market in Korea has evolved through a selective and hierarchical structure, expanding spatially while concentrating exchanges around a small number of innovation-oriented urban hubs.

본 연구는 「기술의 이전 및 사업화 촉진에 관한 법률」 시행 이후 시점인 2001-2020년 사이의 국내 특허 기술거래 네트워크의 형성과 변화를 분석하였다. 특허 권리변동 기록을 토대로 5년 단위로 도시 간 네트워크를 구축하고 ERGM을 적용하여 분석한 결과, 연구 인프라와 혁신 성과가 풍부한 도시를 중심으로 네트워크가 형성되는 것으로 나타났다. 또한, 도시 간 지리적･기술적 근접성이 네트워크 형성에 지속적으로 영향을 미쳤으며, 시기의 후반부로 갈수록 네트워크의 밀도가 상승하는 가운데 상호성과 선호적 연결의 효과가 강화되었다. 반면, 전이성의 효과는 제한적이었으며, 다중경로에 따른 간접연결은 억제되는 경향을 보였다. 이러한 결과는 국내 도시 간 특허 기술거래 시장이 양적으로 성장하는 가운데 선택적, 계층적 구조를 기반으로 형성 및 변화해왔음을 시사한다.
