海洋深層水利活用による地域振興策とその評価

Deep seawater

海洋深層水研究

In order to promote the utilization of deep seawater (DSW) in Rausu Town, northeastern Hokkaido, it is necessary to ascertain in advance the extent to which related industries will influence the production value and other aspects of the town. In the present paper, the process of the feasibility study for the promotion and post-evaluation on the implemented programs were reported. In the feasibility study, characteristics of the current industrial structure were analyzed to clarify the positioning of local marine industries and the income levels of the residents using a regional input-output table. Then the direction of industrial promotion necessary to realize the vision for the future was presented. In the second, seven regional promotion scenarios (four of them are related to DSW) along with twelve specific programs and target values were drawn up to give shape to the industrial promotion policy. Specific target values were given to eight of the twelve programs, and those target values were discussed by the Rausu Marine Vision Council to ensure their realization. Then, the direct effect of the eight programs was examined, and the effect was regarded as the final demand increase in input-output analysis to estimate the economic impacts on the regional economy. For programs that had already been implemented, the degree of goal attainment as well as the problems and challenges encountered were clarified for reevaluation.
