為增加觀光產業的發展，台灣於2002年推動「觀光客倍增計畫」，逐年開放陸客來台，並於2008年通過實施「星級旅館評鑑計畫」，希望相關政策能增長觀光收入。本文建立Cobb-Douglas生產函數模型，以隨機邊界法SFA衡量1997年至2015年間台灣41家國際觀光旅館之相對技術效率，並引入實質國民所得、開放陸客來台觀光、星級評鑑等環境因素，探討造成不效率之因素。實證結果顯示，人均國民所得對國際觀光旅館經營效率影響為正，連鎖型態影響為正，陸客住宿總數影響為負，外國旅客住宿總數影響為正但不顯著。而政策方面，開放開放第二及第三類人士來台對效率無顯著影響，開放陸客「團進團出」以及星級評鑑，則皆呈現正向影響。整體而言,台灣國際觀光旅館產業之經營效率大致呈現緩慢進步之趨勢。研究期間，平均效率最高國際觀光旅館多為國際連鎖且通過5星評鑑；平均效率較低的五家旅館則多為獨立經營，其中有3家未通過或未申請星級評鑑。

In order to promote the hotel industry and attract more international tourists, the government is administering a ＂Dou-bling Tourist Arrivals Plan＂ in an effort to achieve the goal of increasing annual tourists to Taiwan. In this paper, we use stochastic frontier approach by setting a Cobb-Douglas productive function to estimate the relative efficiency of the 41 international tourist hotels in Taiwan during 1997-2015, and to explore the determinants of technical efficiency. The results reveal that real NI per capita and the chain types were positively related to overall technical efficiency, while the total number of guests from Mainland China was negatively related. The total number of guests from abroad was positively related to technical efficiency but not significant. Furthermore, the empirical results show that the impact of the first-stage open-door policy to Mainland Chinese tourists was not significant, but, the second-stage open-door policy and the hotel star-rating system had a significantly positive effect on international tourist hotels' efficiency. Within the sample periods, managerial efficiency of the international tourist hotel industry improved gradually. Most of top 5 technical efficiency hotels were international chain type and got five star rating. By contrast, all of five hotels that efficiency performing poor than others were single-operating, and three of them did not get any star rating.
