The previous research discussed the benefit of river and loss of flooding separately. People in urban lack of nature landscape and open space, so people take river landscape into account for searching house. Besides, flooding causes not only loss of property but also injuries. Therefore, when valuing the river, we have to consider both positive and negative side of river. By potential inundation area map and the house price data, we can transfer the height of flooding into loss of money. So people can realize the influences of river and flooding. Because the data contains spatial heterogeneity and price heterogeneity, using traditional hedonic price method would cause bias. This research use Spatial Hedonic Price Quantile Regression and Taipei city and New Taipei city house price data to calculate the loss of flooding and benefit of living beside Tamsui river in Taiwan. In conclusion, the benefit of living beside river is larger than the loss of flooding. The loss of flooding center on Xinyi District, Neihu District, Wanhua District, Bali District, Shulin District, Danshui District, and Taishan District.5111121 bytesapplication/pdf論文公開時間: 2019/9/8論文使用權限: 同意有償授權(權利金給回饋學校)特徵價格法空間迴歸分量迴歸淡水河景觀效益淹水損失Hedonic Price MethodSpatial RegressionQuantile RegressionTamsui Riverlandscape ValueFlooding Lossthesis10.6342/NTU201602670http://ntur.lib.ntu.edu.tw/bitstream/246246/275815/1/ntu-105-R03627005-1.pdf
