The paper is to conduct the analysis over the cause of airline’s withdrawal from local air routes based on the thorough review of withdrawal facts data from 2001 to 2010.Then, together with the analysis on the status of Europe and the analysis on the future potential of changing air transport in Japan, it addresses appropriate measurers for sustaining and expanding local routes. As a result, it is concluded that (1)High utilization of regional airlines/regional aircrafts, (2)Encouragement of LCC’s entering into local routes and (3)Subsidy scheme to supplement above measures are effective.

Spatial Computable General Equilibrium (SCGE) model is one of the appropriate methodologies to assess the regional distribution of policy impacts including regional benefit. Standard SCGE models treat “multi-country system” or “multi-region in one country system” due to availability of Input-Output table as a data to be calibrated. Recent development of transnational interregional Input-Output table shows a breakthrough in the applicability of SCGE analysis. This paper builds a SCGE model consistent with a transnational interregional Input-Output table considering transport cost explicitly. We furthermore apply the model to a container port investment policy scenario and illustrate regional economic effects quantitatively.

This paper discusses the concept that the commercial vehicle drivers’ hour of service regulations in japan is based on, through comparing with that in EU and US. We point out the needs, firstly to regulate not only working hours but also driving hours, secondly to consider the definition of each term used in the regulations, and finally to force also each driver to manage his/her working and driving hours.
