本文採用新實證產業組織(Newly Empirical Industrial Organization, 簡稱NEIO)於1980年代發展出加碼檢定法(Mark-up Test, 參考Bresnahan，1982；Lau，1982)研究台灣國際觀光旅館產業的競爭行為。並且利用兩階段最小平方法與一般動差法，具體估計驗證台灣國際觀光旅館產業的市場供需互動關係與市場壟斷力指標。最重要之發現乃研究期間(1981年至2006年)，該產業處於競爭激烈環境下經營，以及國際觀光旅館產業平均沒有市場壟斷力來影響市場價格。在研究期間「缺乏市場壟斷力」結果，與所觀察到產業低平均客房住用率、低平均稅前利潤率、並支持該產業日益競爭激烈的市場結構和發生廠商頻繁進入和退出該產業一致。

其次，估計國際觀光旅館客房的需求價格彈性為缺乏彈性，從管理角度來看，企業為了使消費者增加對其旅館客房需求，降價策略可能不是一個非常有效方法。所得彈性為正，意味著國際觀光旅館客房為正常財，顯示總體經濟績效和經濟成長對於拓展台灣國際觀光旅館業務將扮演一個重要角色。關聯性財貨價格交叉彈性為負，表示消費者價格指數上升，使得生活成本增加，引起消費者對客房需求減少。當國外來台旅客人數增加1％時，對旅館客房需求增加約0.2％。最後，當平均客房住用率增加1％時，使得旅館客房需求增加約33,303間或34,651間。

The mark-up test (Bresnahan, 1982; Lau, 1982) is adopted to examine the competitive behavior in Taiwan’s international tourist hotel industry. The most important findings are that the industry was operating in a competitive environment, and that the average international tourist hotel had no market power to affect the market price over the study period (1981-2006). The “lack of market power” finding is consistent with the industry’s low profit and occupancy rates observed and supported by the increasingly competitive industrial structure and the frequent occurrences of entry into and exit from the industry during the study period.
