近年來國內積極投入相關災害研究,各類災害風險資訊益趨完備,然而居民普遍對於環境風險資訊接收不良與防災知識不足,可能使居民面對災害時缺少應變能力,導致生命財產損失更為嚴重。緣此,本研究藉由居民問卷調查,探討不同社經背景居民洪水災害風險認知與趨避之差異,先藉由多項羅吉特模型分析居民風險趨避與風險認知之關聯性;再進一步運用特徵價格模型分析居民風險態度對於住宅價格的影響。研究發現高屏溪流域之「洪水災害瞭解程度」、「住宅移轉面積」、「住宅型式」及「屋齡」等自變數;新店溪流域之「洪水災害風險知覺」、「洪水災害瞭解程度」、「受災經驗」及「住宅移轉面積」等自變數,為影響住宅價格之重要變數。洪水災害之發生,提醒政府重視都市防災課題,進行土地使用規劃時,解析居民風險認知與趨避對住宅價格之影響,有助於規劃出符合實際情況之土地使用規劃,以降低洪水災害的衝擊與生命財產的損失。
In recent years our country actively involved in related disasters research, the various types of disaster risk information was more complete, but residents generally receive poor for the environment risk information and disaster knowledge, that residents could face disaster lack of adaptability, leading to more severe loss of safety of life and property. This study aims to investigate the different social economic background residents’ flood risk cognition and aversion. First, Multinomial Logit Model was applied to analyze residents’ risk aversion and cognition. Further, Hedonic Price Model was used to explain residents’ risk attitude on housing price. The results show the level of understanding flood risk, transaction area, housing type and housing age will affect the housing price in Gaoping River. The level of perception flood risk, the level of understanding flood risk, disaster experience and transaction area will affect the housing price in Xindian River Basin. Flood disasters remind government the importance of urban disaster prevention, when residents’ risk perception and aversion for housing price impact and help implement the land use planning in line with the actual situation, in order to reduce the loss of life and property.
