Tourism, information technologies and sustainability: an exploratory review
本文探讨信息技术（尤其是社交媒体）如何改变全球旅游系统，并从环境、社会文化、心理和经济角度分析这些变化对可持续性的影响，指出信息技术既有负面也有支持可持续旅游的潜力。
Considerable attention has been paid in recent years to the fundamental changes in the global tourism system related to the emergence of information technologies (IT), and, specifically, the rise of social media. Opportunities to search travel-related information, to reserve and book, evaluate and judge; to receive travel advice and to communicate one's mobility patterns have all profoundly changed the practices of performing tourism, with concomitant repercussions for the management and marketing of businesses and destinations. This paper provides a discussion of the implications of these changes for the sustainability of the global tourism system. Based on an exploratory research design, key changes in the tourism system are identified and discussed with regard to their environmental, socio-cultural and psychological, as well as economic significance. The paper concludes that IT affects the tourism system in numerous and complex ways, with mixed outcomes for sustainability: while most changes would currently appear to be ambivalent – and some outright negative – there is considerable potential for IT to support more sustainable tourism. Yet, this would require considerable changes in the tourism system on global, national and individual business' levels, and require tourism academics to probe many new issues.
