租屋市場之租金與住宅品質知多少？

How the Rent and Housing Quality of the Rental Market?

臺灣租屋市場存在住宅品質與租金不對稱的問題，本文利用591租屋網租金資料，以特徵價格理論及空間迴歸模型，分析租屋市場不同類型之租金，於房屋有無分割出租及分割程度不同的情況下，住宅品質差異對租金之影響。實證結果顯示分割房間（雅房、分租套房）及獨立套房每坪租金分別高於整層住家6.5%及2.4%，呈現住宅品質較差但租金單價卻較高的現象。再者，分割程度不同造成住宅品質程度差異，雅房和分租套房、分租和獨立套房月租金分別相差25.9%及11%，其差異來自於有獨立衛浴與有獨立出入口及門牌等。透過本文實證可瞭解不同租屋類型的住宅品質對租金的影響，建議政府未來可建置租金模型估算租金水準，有助於房客客觀衡量租金，減少租屋市場資訊不對稱問題，以健全租屋市場。

Asymmetric housing quality and rent are a big issue in Taiwan's rental market. This study uses the Hedonic price theory and the spatial regression model to analyze the relation between housing quality and rent in different types of rental property based on data scraped from 591 rental websites. Empirical results indicate that “subdivided room” and “studio” properties have 6.5% and 2.4% higher unit price per floor than “apartment” respectively. This finding implies that in the rental market, lower quality housing has higher rental unit price. Furthermore, the empirical results also indicate that the differences between the monthly rent of “room to share” and “subdivided studio”, and between the monthly rent of “subdivided studio” and “studio”, are 25.9% and 11% respectively due to the independent bathroom, doorplate, entrance and exit. The empirical evidence in this study indicates the effect of different types of rental housing on rents. We conclude that the governments should construct a rental model from big data to provide a reference for the renters, reduce the problem of asymmetry in rental market information, and form a sound rental market.
