Nowadays with the proliferation of online consumer reviews, customers typically seek comments from other users before making their own purchase decisions. Although the impacts of online product reviews on consumer behaviors have been investigated by many researchers, relatively less attention has been paid to the role of online reviews in the marketing of service products. Inspired by the strong spending power of Mainland Chinese consumers, this study explores how online reviews of Macau food and beverage outlets may shape Mainland Chinese visitors’ food and beverage consumption behaviors. We are interested in how (1) different attributes of online consumer reviews (e.g., overall rating, length, recency, etc.) and (2) level of restaurant knowledge people gained from reading the online reviews influence the word-of-mouth intention and dining intention of Mainland Chinese visitors to Macau. We conducted an empirical analysis using survey data collected from 150 Mainland Chinese visitors to Macau who have read online reviews of Macau food and beverage outlets. Evidences suggest that overall rating of the restaurant, recency of the review, and abundance of textual information in the review significantly influence Mainland Chinese visitors’ word-of-mouth intention and dining intention. Moreover, product and promotion knowledge people gained from reading online reviews play an important role in shaping their behavioral intentions. Managerial implications on how food and beverage operators may use online review platforms to positively influence consumption behaviors will be discussed.
