Description
Summary:The impact of national projects such as disaster prevention, should be analyzed by simultaneously considering the results of direct and indirect effect analyses. Existing research has verified the effectiveness of disaster prevention projects only through direct effect analysis. This study proposed an impact analysis approach that employed both direct and indirect effect analyses to assess their effectiveness. For the impact analysis, both direct effect and indirect effect analyses were conducted, using cost–benefit analysis (CBA) along with a safety sentiment index of residents and the efforts of the local government in implementing disaster prevention projects in 33 areas in South Korea. CBA calculates the scale of damage through a survey of properties (e.g., crops and public facilities) and the estimated damage according to the conditions of the disaster area. Matrix analysis was performed by applying the results of the CBA and safety sentiment index. The direct and indirect effect analyses identified the highly affected groups and areas where the results of the aforementioned analyses were above average, compared with the lowly affected groups and areas where the results were below average. An area belonging to the group with negative effects could be considered as part of the group with relatively good effects by supplementing its projects. The proposed method of impact analysis can be used to determine the efficiency of a disaster prevention project and comprehensively analyze its effects. •This study suggested an impact analysis system that can consider both direct or indirect effect.•The analysis method that along with two methods were considered was not studied.•Direct effect analysis using CBA(cost benefit analysis) and indirect effect analysis using safety sentiment index of residents.•The matrix analysis was performed by applying the results of the CBA and safety sentiment index of residents.•It is ideal to analyze in two methods to reason out a comprehensive and reasonable result.
