This paper uses the DID method to estimate land price functions based on a hedonic approach for the economic effects of the Fukuoka City Subway Nanakuma Line and the Nishi Kyushu Shinkansen Line, which were extended and newly opened in the Kyushu region between 2022 and 2023, on the areas along these lines. The results of a simple empirical analysis suggest that both the Fukuoka City Subway Nanakuma Line and the Nishi Kyushu Shinkansen have a positive impact on land prices as a whole, but the effect is localized and varies from region to region.

This paper will show the impact of the extension of the Hokuriku Shinkansen from Kanazawa Station to Tsuruga Station by estimating land price trends. Specifically, the MGWR （Multiscale Geographically Weighted Regression） model was used to analyze land price trends using official land price data every five years from 1995 to 2024. The public land price was used as the dependent variable, while land area, distance to the nearest station, and plot-area ratio were used as explanatory variables. It is common in smaller cities for companies and other businesses to be located in the suburbs. This means that public transportation use is comparatively low. What is more, the way people shop has changed significantly over the past quarter of a century, with more people using edge-of-town shopping malls rather than shops around the station. Station areas do not now have the same economic influence that they used to. Local land prices around stations associated with the Shinkansen extension have been raised, but this was not the case with Kanazawa Station and others.

This study examines the heterogeneity in the causal impact of highway development on local employment growth. To this end, we apply causal forests, which is a machine learning algorithm for causal inference, to employment data for the manufacturing sector in Japanese municipalities from 1971 to 2011. We then find evidence that an opening of highway interchange increased local employment by 8.5 ％ on average between 1971 and 1991, while there was no significant impact between 1991 and 2011. We also identify regional characteristics that affected the heterogeneity in the causal effects for each period, and reveal that those differed between periods of economic growth and stagnation.

Though water utilities operate an independent accounting, there are many political interventions as a pricing and a financial transfer. It is important to show an actual balance of payment of water utilities without political intervention. In this paper, we analyzed a cost structure of water utilities and considered sustainable urban situation.
