臺灣地區空屋現象與原因分析An Analysis of Housing Vacancy Rate Phenomenon and Reasons in Taiwan

根據1980及1990年的住宅魯查結果示·臺灣地區兩次普查區的空屋率均維持在13%以上·此結果與歐美國家一般正常3~5%的空屋水準比較,明額偏高兩次普查開及1990年普查後,各縣市的空屋率是否均維持此高水準?是什廢園素造成高空屋率?(是否願含臺灣住宅投資的偏高資本利得預期與偏低的持有成本及租金等現象?)而台灣近年來的偏高房價為何來因高空屋率而有明題的下降?在日前空屋資訊之的情況下·這些疑惑並積合理的解答。因此 本研究首先透過兩次住宅普查與台灣電力公司表燈用電不足底度資料澄清臺灣地區各照市空屋狀況發現臺灣地區歴年空屋率均相當高,而至1993年底空屋數量特續增加進到歷年最高紀錄:約76萬戶空屋·空屋率約為14%·此現象預期對未來房地莊市場不景氣有嚴重深遠的影響。本文其次利用計量經濟模型分析影響臺灣空屋率的主要原因·精此解釋台灣各地區不同的空屋狀況。最後,針對過去空屋現沈與實證結果研擬提高空屋利用之策咯。

According to 1980 and 1990 Taiwan's housing census, the housing vacancy rate was above 13%.Comparing with the reasonable vacancy ratc, 4~5% in the most western countries, the vacancy rate in Taiwan was very high obviously. Is high vacancy rate phenomenon al ways cxist in Taiwan? What are the reasons of high vacancy rate? Does it imply the expectation of high capital gain of housing investment as well as the low holding costs and rents in Taiwan? Due to the lack of vacancy rate information, we can't give a good anwser to above questions. This paper used housing census data and under minimun use of electicity data of Taiwan Power Company to clarify the phenomcnon of housing vacancy rate in Taiwan during every past year. We found that housing vacancy was always high. Up to the end of 1993, the stock of vacant housc was about 760,000 units and the vacancy rate was about 14%. We then establisbed econ-ometric model to analyze the reasons of high vacancy rate. Finally, we suggest some housing stratcgies to solve the high vacancy issue to the government.
