地域間産業連関表を用いたエコロジカル・フットプリント算出に関する研究

抄録

In this paper, the cological Footprint (EF) is the productive capacity numerically quantified as land area required to support a defined economy or population at a specified standard of living. In the present research, the flow of EF between industries can be taken into consideration by an inter I-O analysis. However, the actual conditions cannot take into consideration shipments and naturalization of land resources between areas because it is calculated only within an area. Therefore, a more holistic approach was taken. Provincial productive output data from all industries was gathered and assembled into a multi-regional input-output table. This was then analyzed to obtain the standard physical unit (hectares/yen) from which each regional industry's individual contribution to the EF could be determined. This process was conducted for the nine major regions of Japan as a whole. With this, comparisons between the environmental carrying capacity, as well as the internal EF flows within the country can be made. In conclusion, EF analysis suggests that Japan's economy is ecologically unsustainable.
