The Economic Benefit from Business Interaction between Different Business Activities through High-Speed Rail Operation: An Experimental Concept for the Business Interactive Accessibility and Its Application

抄録

This study evaluates the impact of the business interactive accessibility (BIA) by high-speed railway (HSR) of Japan. The BIA by HSR is a potential interaction for business purposes by HSR, based on the accessibility. Socio-economic conditions affect the BIA, but they have been only considered partially in the accessibility of previous studies. This study develops new variables, Densely-Buoyant District (DBD) at the micro-level and Densely-Buoyant Prefecture (DBP) at the macro-level. The indices denote the BIA considering socio-economic conditions: firms, workers, business scale, and distance between firms within a region. To examine the impact of DBP by HSR, we utilize the production function including DBP, prefecture-fixed effects, and time-fixed effects. The result suggests that DBP enhanced by HSR increases productivity. DBP of the secondary industry and tertiary industry enhances productivity, but not the primary industry. Therefore, the BIA by HSR in the secondary and tertiary industries contributes to regional growth.
