Abstract

This study aims to obtain empirical evidence of disaster mitigation in Bantul, Indonesia. The expected utility theory and impact of regional characteristics on individual perceptions was used to describe the disaster risk management process. The regional mapping based on hazard level was conducted by a Geographical Information System (GIS). Data used in this research were primary and secondary data. Primary data were obtained by distributing questionnaire to some respondents. Sample amounts used were 395 respondents. The research empirical contribution was to economic valuation method used towards safety and efforts to link regional characteristics, individual perception and also their willingness to conduct mitigation. The research practical contribution was to identify some key obstacles in disaster risk management. Based on multiple regression analysis, this study found that educational level, risk aversion degree, trust towards earthquake-resistant building, control ability, income level, classifi cation of hazard area contributes to higher Willingness To Pay (WTP) for mitigation. It also found that perception towards central governmental roles variable did not affect to WTP for mitigation. However, the income levels of the communities in Bantul positively correspond to WTP for mitigation suggesting that the fi ndings were consistent with the expected utility theory.
2006年5月班图尔地震后减灾案例的风险认知与经济价值
本研究旨在获得印度尼西亚班图尔的减灾经验证据。期望效用理论和区域特征对个体感知的影响被用来描述灾害风险管理过程。利用地理信息系统(GIS)进行基于灾害等级的区域制图。本研究使用的数据为一手数据和二手数据。通过向部分受访者发放调查问卷,获得初步数据。使用的样本量为395名受访者。该研究的经验贡献是用于安全性的经济评估方法,以及将区域特征、个人感知及其进行减灾的意愿联系起来的努力。该研究的实际贡献是确定了灾害风险管理中的一些关键障碍。基于多元回归分析,研究发现受教育程度、风险规避程度、对抗震建筑的信任程度、控制能力、收入水平、危险区分类对减灾支付意愿有较高的影响。研究还发现,对中央政府角色变量的认知对缓解WTP没有影响。然而,班图尔社区的收入水平与缓解WTP呈正相关,这表明研究结果与预期效用理论一致。
