도로교통 R&D와 정부정책의 공진화 분석 : 2003∼2022년 국토교통 R&D 대상으로
Co-evolution Analysis of Road Transportation R&D and Government Policy : For R&D projects in the Land and Transport from 2003 to 2022
Abstract
Technological paradigm shifts in the road transportation sector arise from intrinsic technological progress, yet they are also substantially shaped by government policy. This study examines this co-evolutionary relationship by analyzing 2,174 Research and Development (R&D) projects funded by the Ministry of Land, Infrastructure and Transport between 2003 and 2022. Using keyword analysis, N-gram analysis, and word similarity–based clustering, we identify distinct shifts in R&D priorities that align with the policy orientations of successive administrations. The findings indicate that government policy is a decisive driver influencing the thematic direction and developmental trajectory of road-transport technologies. This study contributes an empirical framework for analyzing technology–policy interactions and offers practical implications for strategic R&D planning and policy formulation in the transportation sector. Our results highlight that policy choices can actively shape, accelerate, or redirect technological paradigm transitions.
