Abstract

The recent trend suggests that people are more inclined to online hotel reviews to take online hotel booking decisions. The present study argues that when consumers are exposed to online hotel reviews, it draws an impression of the hotel brand in the mind of consumers, resulting in influence their hotel booking intentions. The current study determines the mediation effects of brand image between credible online hotel reviews and consumers’ hotel booking intentions. To ascertain the uni-dimensionality of the scales, the present study executes exploratory factor analysis. The ensure the internal consistency of the variable scales, the study determines Cronbach’s alpha. To measure the mediation effects, the present study performs structural equation modeling bootstrapping method. Data analysis reveals that marketers should look at hedonic brand image, which ultimately influences consumers’ hotel booking intentions. This is a unique study that ascertains the type of brand image that actually mediates between the impact of online hotel reviews and consumers’ hotel booking intentions. In addition, the paper furnishes theoretical background on how people interpret online hotel reviews and its effects.  相似文献

世界500强跨国公司具有显著技术优势,500强企业的战略调整有利于我国利用大型跨国公司投资促进技术进步。吸收500强跨国公司投资是我国促进技术进步和产业升级的重要措施。但是吸收大型跨国公司投资既有促进技术进步的作用,又有技术垄断的负面影响。吸收大型跨国公司的竞争性投资有利于营造竞争环境,打破技术垄断,并将我国国内产业竞争推进到国际竞争的前沿。  相似文献

核心竞争力是企业适应市场的潜力。中国某些企业由于缺乏核心竞争力而使其市场份额逐渐缩小。为了适应国际市场竞争的形势,发展企业核心竞争力是重中之重。为此,除了企业加强自身建设以外,政府应该利用法律和政策,充分利用加入WTO以后宝贵的“缓冲期”,使国内市场尽快完善,促进企业核心竞争力的不断提高。  相似文献

The conceptualization of integrated marketing communication (IMC) has evolved from the marketing communications-centered approach (in the early 1990s) to a broader, firm-wide organizational perspective. The latter is adopted in this research to define IMC as a multidimensional concept. This study was conducted to develop a measurement instrument to assess IMC and examine the role of organizational culture in IMC implementation. Data were gathered via an online survey conducted among CEOs and other senior managers. The findings provide evidence of the reliability and validity of the proposed IMC scale and demonstrate that the dominance of an adhocracy (vs. market) culture contributes to building a more IMC-friendly organizational environment.  相似文献

This paper addresses the theoretical framework on corporate social reporting. Although that corporate social reporting has been analysed from different perspectives, legitmacy theory currently is the dominating perspective. Authors employing this framework suggest that social and environmental disclosures are responses to both public pressure and increased media attention resulting from major social incidents such as the Exxon Valdez oil spill and the chemical leak in Bhopal (India). More specifically, those authors argue that the increase in social disclosures represent a strategy to alter the public's perception about the legitimacy of the organisation. Therefore, we suggest using corporate communication as an overarching framework to study corporate social reporting in which corporate image and corporate identity are central.  相似文献

Mobile communication failure can occur when mobile traffic exceeds the manageable level. This depends on frequency bandwidth. Mobile communication failure causes inconveniences in a user's daily life that lead to social and economic damage. To address this issue, mobile telecommunications companies deploy additional bandwidths and develop new technologies, but these are costly strategies. This study applies a spike model based on a contingent valuation method (CVM) to measure the inconvenience cost resulting from mobile communication failure. The mean monthly willingness-to-pay (WTP) to avoid communication failure per user is estimated to be KRW 898.14 (USD 0.80) over a period of five years in our study. The inconvenience cost borne by the population is estimated to be KRW 2.97 trillion (USD 2.61 billion). Users experiencing greater frequency of communication failure are found to be willing to pay more to avoid the inconvenience. When excluding respondents citing zero-WTP, the mean WTP per user was calculated to be KRW 3426.41 (USD 3.01). Data traffic usage and frequency at which communication failure is experienced are variables that exhibit statistically significant effects on WTP to avoid mobile communication failure. Overall, estimation results show that a price discrimination based on data traffic usage or quality can be considered by mobile telecommunications companies and regulators to address the issue of data traffic inducing mobile communication failure.  相似文献

Despite the significant role that the visual plays in the experience of tourism, few studies have specifically examined the visual appearances of heritage tourist destinations. This study sought to analyze how historically grounded the visual appearances were of two heritage tourist towns in the state of Arizona: Tombstone and Jerome. These towns were both mining towns that experienced historic booms during the days of the American Old West and survive today as tourist destinations. This study utilized a detailed visual comparison of historic and contemporary town photographs in order to assess the relative historic-grounding of building exteriors and streets. It also incorporated the findings of interviews with tourists and town residents regarding their perceptions of visual historic-grounding. Study findings offered a means to assess and compare visual historic-grounding. Additionally, they suggested that while visual historic-grounding was important to visitors, it was one of several factors influencing their perceptions of the town's historic appearance: visual appeal, personal reflections, engaging activities, and previous visitor expectations of the American Old West (often grounded in filmic-representations) worked together to visually communicate a general impression of history within each town.  相似文献
