本研究以特徵價格理論為基礎，分別以新竹地區透天住宅每坪房價以及房屋總價作為應變數，並以路寬、屋齡、移轉土地坪數、移轉房屋坪數等自變數加上奢侈稅以及都會區等虛擬變數建立多元迴歸模型；另外依人口密度高低將樣本區分為實驗組與對照組，進而搭配差異中的差異分析法來探討特種貨物及勞務稅條例(俗稱奢侈稅)實施對於新竹地區房價的影響。 特種貨物及勞務稅條例於2011年6月施行，本文將人口密度較高之新竹東區、北區與竹北市設為實驗組，而前述以外之新竹其他人口密度較低區域則設為對照組，並以2010年第2季至2012年第2季作為研究期間。 由實證結果可以看出，在房屋特徵變數的部分，以透天住宅總價取對數做為應變數，較以每坪房價做為應變數的模型具有更合理的實證結果，也就是說半對數(log-level)的函數型態對房價的變化具有較佳的解釋能力。而在奢侈稅實施效果的部分，無論是以東區、北區以及竹北市等三個區域共同設為實驗組與對照組做比較分析，或是分別以東區、北區以及竹北市三個群組各自設為實驗組與對照組進行模型分析，其實證結果皆顯示政府對房地產課徵奢侈稅的政策並無法有效的抑制新竹地區的房價。因此，政府應該要有更積極的作為，才能抑制房價的上漲，進而減少社會大眾對於高房價的民怨。;Special Goods and Services Tax Regulations were implemented in June 2011. By using difference-in-difference method in which the townhouses in the East Hsinchu, North Hsinchu and Chu-Pei City are the experimented group, where the townhouses in other districts of Hsinchu are the controlled group, we analyze the effect of the implementation of special goods and services Tax (Luxury Tax) regulations on housing price during the period of July, 2010, to July of 2012. Based on the hedonic price theory, we conduct an empirical model in which the price per pyeong and the total price of a townhouse are dependent variables, in addition to the indicator of the implementation of luxury tax, the road width, house age, the land area and the house area are independent variables Our empirical results show that the government’s imposing luxury tax on real estate cannot effectively restrain the housing price in Hsinchu. Therefore, the government should act more positively so as to rein in property price rises and then reduce popular discontent over high housing price.
