近年來房價持續攀升，政府決定實施特種貨物及勞務稅條例以降低投機買賣之行為，達到防止房價泡沫化，平抑房價之目的。為探討資本市場對該條例之預期，本論文首先以事件研究探討特種貨物及勞務稅條例消息公布之際，上市櫃建設公司是否產生負的累積異常報酬率，並採用迴歸模型探討公司特性與該公司受特種貨物及勞務稅條例影響幅度的關聯性。本論文進而透過對上市櫃建設公司營業收入及營業毛利率在特種貨物及勞務稅條例消息公布後是否產生不利影響之探討，了解特種貨物及勞務稅條例消息公布對建設公司銷售面之實質影響，最後採用迴歸模型探討公司特性與建設公司銷售面受影響幅度之關聯性。 本研究研究結果發現： 1、在特種貨物及勞務稅條例消息公布之相關事件日，上市櫃建設公司普遍均產生顯著的負向股票異常報酬率。 2、股票累積異常報酬率與公司特性關聯性之迴歸結果顯示，研議及開徵特種貨物及勞務稅消息公布之事件日，存貨比率較高、公司規模較大、公司成長性較高之上市櫃建設公司，其累積異常報酬率較低。 3、在特種貨物及勞務稅條例消息公布後，上市櫃建設公司之營業收入產生不利影響，但對營業毛利率並無顯著之不利影響。 / In order to curb the housing price hike and prevent housing bubble, Taiwan government implemented the Specifically Selected Goods and Services Tax Act. The Act is expected to have negative impacts on stock market returns of construction companies and real estate market. Using event study method, this study examines the stock market reactions to the announcements of the legislature policy. This study explores the relation between the stock cumulative abnormal returns (CAR) of the Act and firm characteristics. This study finds that the stock market reacts negatively when the news of the Act are released. The regression results indicate when the news of the Act are released, for construction companies, CARs are negatively related with inventory-to-total assets ratio, corporate size and growth. This study also finds the construction companies’ revenue reflected the negative impacts on real estate market.

2010年台灣經濟成長率創新高，然貧富差距卻是台灣面臨最大問題之一，為避免大眾不良觀感，行政院乃針對高價服務、商品或交易，研議特種銷售稅，即通稱之「奢侈稅」，並於2011年通過與施行「特種貨物及勞務稅條例」。各國採行特種銷售稅種類繁多，課徵目的、稅率各有不同。究竟我國課徵奢侈稅制度與他國制度有何不同? 課徵奢侈稅效果為何?此為本研究主要動機。 本研究針對上述問題，採文獻分析與深度訪談法，進行深入的分析與探討。經實證分析發現：（1）主要國家課徵奢侈稅，課徵項目與目的各異。（2）解決不動產飆漲問題，多管齊下多重效果。（3）透過交易稅抑制投機，短空長多。（4）國際間相互依存，政府政策相互影響。（5）資訊透明化是決定市場機制能否發揮功效之關鍵之一。（6）不動產市場存在三種價格，阻礙不動產市場發展，更違反社會正義。（7）我國房價高漲主因財產稅稅負偏低。 / Although economic growth in Taiwan hit an all-time high in 2010, the gap between the rich and the poor has become one of Taiwan’s most serious issues. The Executive Yuan, in an effort to avoid negative public perceptions, held deliberations on a special sales tax for high-priced services, goods and trade, also commonly known as a “luxury tax”. The “Specifically Selected Goods and Services Tax Act” was sent to the Legislative Yuan for review 2011. Countries around the world have implemented many kinds of special sales tax. Such taxes differ in regard to their intended purpose and imposed rate. Exactly how does Taiwan’s imposed luxury tax differ from those of other countries? What has been the result of imposing the luxury tax in Taiwan? Finding out the answers to these two questions is the primary objective of this paper. This study conducted literature analysis and in-depth analys. Through the empirical analysis we found that: (1) The items and reasons for taxing should be considered separately. (2) In addressing the issue of soaring real estate prices, multi-pronged approaches bring multiple results. (3) Transaction taxes to control speculation result in short-term pain, but long-term gain. (4) Because of the interdependent nature of nations, the government policies of a given nation influence other nations. (5) information transparency is a key factor in deciding whether or not market mechanisms can be effectively leveraged. (6) the existence of three different prices in the real estate market is a barrier to the development of the market and, more importantly, violates the principles of social justice. (7) the main reason behind the rocketing price of housing in Taiwan is the low property tax burden.
