| Summary: | 碩士 === 國立成功大學 === 都市計劃學系 === 106 === Housing prices in Taiwan have grown 1.8 times over the past decade. Housing prices have risen faster than the growth rate. In the past, studies on the affordability of home purchases by households were generally based on the price-to-income ratio as the ability of households to buy houses In order to be more consistent with the household purchase affordability, this study estimates the affordability of household purchase by the concept of residential ceiling proposed by Gan and Hill (2009).
Because residential buildings are a heterogeneous property, there are many different types of housing markets in the metropolitan area. This study will address the six metropolitan areas of Taiwan (Taipei, New Taipei, Taoyuan, Taichung, Tainan, Kaohsiung ) To estimate the pressure on the affordability of homebuyers through the indicator of the affordability of homebuyers and to explore the affordability of the affordance by using the Spatial Autocorrelation method. Finally, the related plans are nested to illustrate the characteristics of different regions .The results show that the housing prices in the six metropolitan areas of Taiwan in the northern region of the overall price is more concentrated in central and southern regions are more scattered distribution, and further from the Moran'sI value results can be seen that the pressure on the purchase of housing The spatial distribution also shows a cluster of similar features in the north. Central and Southern China has a multi-level distribution. Knowing the possible reasons for the distribution of residential markets and the affordability, finally, the LISA results show that the high pressure on homebuyers' However, in Taichung City, Tainan City and Kaohsiung City, although there are some high-value aggregates in space, the overall distribution is relatively fragmented, It is inferred that due to the different characteristics of the housing market in the northern and central-southern regions, the northern part is dominated by elevator buildings, while the central and southern parts are the elevator towers and trans-day houses. In observing changes in the pressure values of housing affordances The relationship expectation can further make relevant policy suggestions and will be helpful for the analysis and research of the subsequent housing market.
