Abstract
The traditional Cost-Benefit Analysis has a limitation that it can evaluate a project only on the efficiency criterion. This study proposes Cost-Benefit Analysis with Regional Weight so that a project can be evaluated on both efficiency and equity criteria. Regional Weight is a coefficient to add an extra benefit to a regional benefit considering inter-regional imbalance. This study showed that this coefficient could be derived from social welfare function. Also the easiness and practicality of this method is shown in a case study. The Regional Weight illustrated in the case would be a proto-type for practical use.
