從供給主體探討高雄市集合住宅的供給特性與發展脈絡

A Research on the Supply Characteristics and Evolution of Congregate Housings in Kaohsiung City on the Basis of Supply Subject

自2001年起高雄市已成為全台人口密度最高的都市。此外，隨著近年高雄市政府陸續推動重大建設，使高雄市住宅建設及供給動向成為不可忽視的課題。近年國內關於高雄市住宅之相關研究，主要以探討住宅市場、都市計劃、住宅政策與居住環境方面居多，反觀針對高雄市集合住宅的建築計畫及行政區之住宅供給的相關文獻則相當匱乏。故本研究透過高雄市建管處所列管之使照資料及竣工圖面，首例採全面性調查，針對自1970年至2008年間，高雄市國民住宅與民間集合住宅共計5120件，企圖從「供給主體」、「基地規模」、「時間軸」與「區域性」等研究視點，探討高雄市近四十年來集合住宅之供給特性與發展脈絡。本研究結果得知，歷年高雄市不論國民住宅或民間集合住宅，其開發規模皆呈現小規模且多件數之供給傾向，且同時具少戶數、住棟少量化及低樓層高建蔽率之供給特性，同時歷年也皆維持一定的居住品質，尤其近年之居住水準呈顯著提升。另外，兩者隨著基地規模的增加，其總戶數、總樓地板面積、住棟數、樓層數，以及每戶面積等皆呈現成長的供給特性。

Since 2001, the density of the population in Kaohsiung City has become the highest in Taiwan. Furthermore, following the development of momentous constructions in recent years, the trend of housing construction and supply has become an important issue.Contrary to the available literature relating to the housing market, urban planning, housing policies, and living environment in Kaohsiung City in recent years, literature on the construction plan of congregate housings and housing supply in administrative districts is rather limited. Based on the completed drawings and related information provided by the Public Work Bureau of Kaohsiung City, this research conducted the first comprehensive survey on 5,210 cases of public housings and private congregate housings constructed from 1970 to 2008 in Kaohsiung City, focusing on the aspects of 'supply subject', 'base scale', 'time frame', and 'regionalism', to explore the supply characteristics and evolution of congregate housings in Kaohsiung City over the past 40 years.According to the findings of this research, the development of public housings and private congregate housings in Kaohsiung City over the years has shown a trend of 'small scale and multiple cases' as well as supply characteristics of few householders, few stories, and low stories with higher building coverage ratio. Moreover, public housings and private congregate housings have also maintained a stable living quality over the years, showing a significant rise in recent years. In addition, with the increase in base scales, the total number of households, total floor area, housing quantity, number of floors, and household size of both public housings and private congregate housings have exhibited a trend of growth in terms of supply characteristics.
