Amartya Sen emphasizes that it is impossible to evaluate the well-being of the person without knowing what the person can do with the commodities and characteristics at his or her command, namely functionings of the person. The capability approach in which a combination of functionings and opportunities determines individual capabilities is urgently required as well in evaluating regional transportation system. For instance, construction of even magnificent highway in a region has a small or almost nil effect on the well-being or happiness of a resident if he or she is aged, ill, has no car , or no driver's license. Resorting to Survey of satisfaction-with- activities of residents, this paper intends to evaluate regional transportation system from the viewpoint of resident's happiness by the Sen's capability approach.

The purpose of this article is to analyze the impact of high-speed transport infrastructure development on regional economies. Then we have developed multi-regions and multi-sector model by using an interregional input-output tables from 1965 up to 2000 which covers nine regions of Japanese economy. By this system, we conducted the scenario analysis in case of no development of high speed transportations. As a result, we could uncover the mechanism of economic disparities among regions in terms transport infrastructure.
