〔記者徐義平/台北報導〕對比第二季全國屋齡30年以上的房屋稅籍住宅高達588.43萬宅,5年內新屋卻僅67.9萬宅,連70萬宅都不到,也造成老屋、新屋數量有著極大落差,甚至全國老屋、新屋比高達8.67:1。
馨傳不動產智庫執行長何世昌表示,近幾年進入預售屋完工交屋潮,使照核發量走升,完工的新屋量並不小;新屋比率甚低的主因是老屋存量可觀,拆除重建速度緩慢。由於老屋比例高,以及國人普遍只有裝潢意識,普遍缺乏整建、維護房子的觀念,居住安全將最艱辛的挑戰。

進一步觀察第二季22縣市5年內新屋占比,以基隆市最低、僅約3.43%,占比第二低則是台北市、約3.56%,平均28.09宅才有1宅是5年內新屋,而其它五都的新屋占比,以桃園市最高、約11%,其次則是台中市、約10.01%,其它三都占比均不到9%。
台北市5年內新屋占比不到4%
信義房屋不動產企研室專案經理曾敬德表示,疫情過後建案開工興建數量增加,桃園、台中、新北、高雄都有不少新案推出,房價從疫情後上漲幅度也可觀,連帶雙北以外的大樓推案也出現小宅化趨勢。
高力國際不動產業主代表服務部董事黃舒衛表示,新屋供給量主要看三個面向,首先是素地供給,其次是都市更新及危老等重建,最後則是房市需求量。進一步從各縣市來看,台北市缺乏重劃區、造成土地稀缺,基隆市受限於地形因素,因此兩縣市可供開發的土地庫存量最低,新屋比率自然有限。
相對來說,桃園市大量農地透過區段徵收、市地重劃,青埔高鐵重劃區、草漯重劃區、中路重劃區、經國重劃區、小檜溪重劃區等多個重劃區,提供大量土地原料,再加上雙北市外流人口及產業投資帶動,以及交通建設拉近產品的替代性,引爆區域的建築開發投資暴增,因此新屋占比最高。

Affected by the high housing prices in Shuangtai City, home buyers with limited budgets have expanded to Taoyuan and surrounding counties and cities in New Taipei City to purchase properties. Statistics from Yongqing Real Estate Group show that among the top five administrative districts in North Taoyuan with the highest population growth in the past year, Taoyuan City's Grand Park has the highest growth rate of 2.9%, followed by New Taipei City's Tamsui District at about 1.7%, and Taoyuan City's Guanyin District and Guishan District tied for third.

Earthquakes are frequent in Taiwan, and Taichung's super-high-rise residential and large-scale construction projects are advancing.

However, only 0.009% of the number of old houses approved for reconstruction was approved.
