Abstract: Abstract Energy intensity improvement is an influential policy agenda for global environmental problem-solving and sustainability enhancement. This study focuses on inter-regional networks’ impact on energy intensity and statistically examines whether the improvement of such networks promotes a modal shift from passenger vehicles to railways. The results indicate the nonlinear relationship between the improvement of inter-regional networks and the variation of the passenger vehicle sector’s energy consumption. Furthermore, the results reveal that the laying of high-speed railways, which helps strengthen inter-regional networks, can significantly improve regional energy intensity. This result has valuable implications for Japan’s national land plan. The high-quality transportation infrastructure, such as high-speed railways, to be introduced in the country can potentially change the energy consumption patterns in inter-regional travel and improve energy intensity. Our results suggest that the installation of the high-speed railway will effectively reduce carbon dioxide emissions. This revelation is expected to provide new policy evidence to scholars and policymakers.
