Sunbin Yoo 교수의 연구실은 교통 인프라의 사회경제적 영향과 지속가능성 문제를 중심으로 연구를 전개합니다. 고속철도의 도입이 도시와 농촌의 경제적 격차를 어떻게 확대하는지, 자율주행차에 대한 소비자 수요와 환경 인식의 상관관계를 분석하며, 철도 확장이 대기질과 공공보건에 미치는 장기적 영향을 규명하고자 합니다. 특히 정책적 영향을 고려한 실증적 분석과 다차원적 데이터 기반 모델링을 통해 실질적인 사회적 해결책을 모색합니다.

This study examines the effects of high-speed railways (HSRs) on gentrification in Japan from 2000 to 2019, using indicators including land prices and income levels. Using the market access index and instrumental variable strategy, we establish a causal relationship between HSR expansion and gentrification. The results show a 39.38% increase in urban land prices and 6.20% rise in urban income compared to a 21.13% decrease in rural land prices and 3.33% decrease in rural income. Additionally, rur
We review the literature on the motivators of consumers’ purchasing decisions regarding autonomous vehicles (AVs), focusing on environmental awareness, vehicle types, concerns about accidents, and merits. The willingness to buy (WTB) and willingness to pay (WTP) for AVs have been extensively studied. However, it is imperative to broaden the outlook and consolidate the existing knowledge base. Although the WTB and WTP for AVs have been studied, automation-level preferences have been underresearch
Over the past 35 years, the development of high-speed rail (HSR) in Japan has markedly enhanced market access and altered spatial distributional dynamics, thereby transforming the socioeconomic landscape in both urban and rural areas. This study delves into the impact of improved market access on regional disparities, with a particular focus on the shifts in population and economic activity between urban centers and their surrounding peripheral regions. We examine three key hypotheses: (1) HSR i
We explore the long-term impact of railway infrastructure on air pollution by examining Japan’s railway network expansion over a 25-year period. Using Difference-in-Differences, regression analysis with market access, and instrumental variables strategies, we identify a causal link between railway development and improved air quality. Our findings show that railway expansion significantly reduces Suspended Particulate Matter (SPM) by 9.576% to 21.65% and Nitrogen Dioxide ( N O 2 ) by 1.401% to 1
