Smart Tourism Technologies in the Industry 4.0 Era: A PRISMA-Based Systematic Review of Adoption, Implications, Outcome and Future Direction

Abstract

The rapid nature of Industry 4.0 advancements has facilitated the adoption of smart tourism technologies in tourism and hospitality industry, which has fundamentally changed the ways that services are offered, operations and customer experiences. The paper is a systematic and comprehensive review of smart tourism technologies, that is, artificial intelligence (AI), big data analytics, the Internet of Things (IoT), chatbots, service robots, and immersive technologies, including virtual reality and augmented reality. The research is conceptualized under the PRISMA framework, which implies the screening of 142 peer-reviewed journal publications published in 2011-2025. The study uses the narrative and thematic synthesis to discuss significant tendencies in the acceptance of technologies, methodology, theoretical frameworks, and outcome dimensions in the study of smart tourism. The findings indicate that academic interest has increased exponentially since 2020, and most of the articles employ quantitative and technology adoption theory, such as TAM, UTAUT, and the S-O-R model. The review demonstrates that customer satisfaction, customer engagement, customer loyalty, operational efficiency, service quality, and organizational sustainability are positively affected by smart tourism technologies. However, the concerns of confidentiality, ethical considerations, employee well-being, and geographical shortcomings of research remain eminent. Combining fragmented literature by offering an integrated approach, the research paper aids in gaining a better insight into how smart tourism technologies affect experiential, operational, and sustainability outputs. The findings can significantly contribute to the theoretical understanding of researchers and offer practical suggestions to tourism managers and policymakers who tend to adopt a responsible and human-centered digital transformation in Industry 4.0.
