現今顧客需求越趨多元化的情形下，餐飲業者均以提供高品質服務，甚至超越顧客期望為目標。本研究主要探討當服務太過專注於超乎顧客期待，而成為「過度服務」時，對服務品質、滿意度與再購意願的干擾影響。因此，研究目的共計六項：一、探討服務品質對滿意度之影響，二、探討服務品質對再購意願之影響，三、探討滿意度對再購意願之影響，四、探討過度服務對服務品質與再購意願之干擾效果，五、探討過度服務對滿意度與再購意願之干擾效果，以及六、探討過度服務對服務品質與滿意度之干擾效果。本研究採問卷調查法，並於網路進行樣本蒐集。主要研究結果共兩項：一為餐廳業者的服務品質越高，顧客滿意度則越高；顧客滿意度越高，再購意願也越高，唯服務品質與再購意願之間並未達顯著，但若透過滿意度，即可影響再購意願而達顯著。二為過度服務對於服務品質與滿意度之間、服務品質與再購意願之間，以及滿意度與再購意願之間，皆無顯著干擾效果。故本研究推論過度服務，並非影響顧客滿意與再購的主因；再者，儘管過去的研究皆對於過度服務持負面影響，但是，對於年輕族群而言，似乎過度服務是可以被接受的，且不影響服務品質、滿意度與再購意願。

In response to the increased variability in customers' demands, the food and beverage industry strives to provide best quality services that often even surpass customer expectations. This research focuses on when services are over-attentive and surpasses customer expectations, turning into ＂over-service＂, which would in turn affect service quality, satisfaction, and repurchase intention. Therefore, there are six research purposes: 1. How service quality affects customer satisfaction? 2. How service quality affects repurchase intention? 3. How customer satisfaction affects repurchase intention? 4. What moderating effect of over-service on service quality and repurchase intention? 5. What moderating effect of over-service on customer satisfaction and repurchase intention? 6. What moderating effect of over-service on service quality and customer satisfaction? Survey questionnaire has been applied and data was collected via the internet. Two main conclusions are as follows: First, the higher the service provided, the better the customer satisfaction; the higher customer satisfaction, the higher the repurchase intention will be. However, there is no significant influence between service quality and repurchase intention, but it may possible be significant influence via customer satisfaction. Second, there are no moderating effect of over-service on service quality and customer satisfaction, service quality and repurchase intention, as well as customer satisfaction and repurchase intention. Hence, this research may infer that over-service would not be the main reason for customer satisfaction and repurchase intention. Even though literature point out the negative perception of over-service, young people seem to take it as acceptable in terms of service quality, satisfaction and repurchase intention.
