Impacts of high-speed rail construction on land prices in urban agglomerations: Evidence from Kyushu in Japan

High-speed rail integrates regions and cities, and thus can possibly have significant impacts on the distribution of economic activities. Using the opening and extensions of a high-speed rail, Shinkansen, in Kyushu, Japan, we examine its effects on land prices in urban agglomerations, which would reflect changes in the distribution of economic activities across urban agglomerations. We estimate hedonic price equations to conduct a difference-in-differences analysis. We find that the large metropolitan areas gained from the high-speed rail by experiencing increases in land prices, whereas small metropolitan areas located between them lost by experiencing decreased land prices. However, such positive effects are shown to be limited to areas close to Shinkansen stations.
