本研究使用「價格相關係數法」、「共整合ARDL邊界檢定法」以及「價格比例-單根檢定法」三種方法，界定台灣國際觀光旅館業的經濟市場。根據2006年8月至2013年4月，台灣省十二個縣市的客房租金價格月資料，三種方法的市場界定結果有以下發現：(一)以全國為界定對象，「台中、嘉義、台南、高雄、宜蘭、花蓮」六個縣市為同一市場；(二)以北、中、南、東四個地理區域為界定對象，中南部地區「台中、南投、嘉義、台南、高雄」五縣市為同一市場，東部地區「花蓮、台東」兩縣市為同一市場。綜合以上結果，本研究推論台灣國際觀光旅館業者具跨縣市的市場關係，似乎愈鄰近的地區愈可能屬於同一市場。

This study adopted three delineation methods (price correlation, ARDL bounds test and price-ratio unit root test) and used 12 counties’ monthly room rates to delineate for Taiwan international tourist hotel market. The main findings of the study are presented as follows: (1) take the whole country as delineation object, "Taichung, Chiayi, Tainan, Kaohsiung, Yilan and Hualien," the six counties constitute same market; (2) take north, central, south and east, the four geographic regions as defined object respectively, in central and southern regions, "Taichung, Nantou, Chiayi, Tainan and Kaohsiung," the five counties constitute same market and in the eastern region, "Hualien’ and ‘Taitung" constitute same market. In conclusion, this study suggests Taiwan international tourist hotels constitute inter-regional markets, and it seems more likely that the hotels belonging one market if their location are much close.
