    Abstract: 近年來國人旅遊風氣盛行,旅遊產業規模日益增大也帶動了住宿業的商機。根據中華民國交通部觀光局的統計,2015年國人國內平均旅遊次數為8.5次,國外旅遊平均為0.56次。與2014年相比,國內旅遊總旅次成長了14.25%,國外總旅次則成長11.3%;旅遊總費用亦有可觀的成長,其中住宿又是主要的支出項目,約占旅遊總支出的33%。隨著網際網路的發達,消費者對旅遊規劃的自主性提高,帶動自由行的風潮,也讓訂房網站得以快速擴張。然而訂房網站面對的是一群價格敏感度較高的消費者,同時產業內多元的競爭者也讓網站業者面臨更激烈的價格競爭,大多以強調低價為主要的行銷手段。本研究欲探討訂房網站行銷4P策略,特別是價格策略,對顧客滿意度與忠誠度之影響,以及影響訂房網站滿意度之消費者心理因素。

    本研究透過文獻探討決定研究變數並建立研究架構,再以問卷調查的方式蒐集初級樣本資料,共蒐集295份有效問卷,並以敘述性統計及迴歸分析等方法進行假設驗證。

    研究結果發現低價策略及價格/非價格促銷策略皆無法讓消費者同時達到行為及態度忠誠。網站品質、關係行銷策略以及主打經驗性的品牌形象可以透過提升滿意度進而達到顧客忠誠。然而本研究發現當消費者有安全或隱私風險的疑慮時,會對常態性低價策略及短期的價格促銷的滿意度造成不同的影響。本研究認為訂房網站必須跳脫價格競爭的泥淖,做出差異化的策略,同時保障消費者個資以及交易安全,才能確保永續經營的優勢。
    The expansion of tourism industry has thrived the online accommodation reservation market. The increased popularity of Internet has lowered the cost of information search and inspired people to become more willing to arrange their tours online. Consumers who reserve accommodation online are considered more price sensitive than those who do so through the offline channel. In order to attract consumers, online travel agencies (OTA) use different marketing tools, and put special emphasis on providing price incentives such as EDLP strategy or temporary price discount. In this study, we investigate how OTAs’ marketing strategies (including product attributes, price strategy, website quality, promtions and brand image) influence customer satisfaction and loyalty. Also, we will find out whether consumers’ perceived risk will influence the effectiveness of OTAs’ pricing strategy.

    A total number of 295 samples were obtained through Internet questionnaire conducted by the study. It was found that
    1. EDLP has significantly positive effect on satisfaction while temporary price promotion doesn’t. However, both pricing strategies aren’t able to achieve complete customer loyalty, which is comprised of behavioral and attitual dimension.
    2. The loyalty program of OTA has significantly negative effect on satisfaction.
    3. Enhancing website quality, conducting relationship marketing and creating experiential brand image have significantly positive effect on both satisfaction and loyalty.
    4. Consumers’ perceived risk will pose different effect on EDLP and temporary price promotion.
