This paper aims to present the evolution and change in content in tourism, over time, as well as the emergence of different sustainable tourism concepts (ST). For this purpose, a comparative Automated Content Analysis (ACA) is herein applied to scientific articles published between 1990, when the first article in this field was published in the Web of Science, and the end of 2020. The results show some overlaps between the concepts that have emerged over the periods. According to the analysis results, it can be concluded that the theme focuses on business model changes, adoption of organizational processes related to the provision of mitigation measures, implementation of cleaner and smarter technologies, the importance of cultural heritage for sustainable tourism product concepts, rural development, green investment, sustainable standards and sustainable reporting.

Purpose – The purpose of this paper is to find out the significance of the social innovation in tourism according to the business concepts of the social economy which requires as much care and creativity in their generation as the social ideas. The goal of the social innovation has to be in terms of meeting social needs and achieving economic sustainability. Methodology – The paper examines critical factors that influence on the role of the social innovation in organizational change in tourism firms and value creation of the tourist social innovation projects in rural areas. The purpose of this systematic literature review is to gather all research literature related to the application of social innovation in tourism in recent years, and to provide an overview of it, as well as evaluating the effectiveness of social innovation in addressing innovative business models in tourism. Findings – The paper contributes to discussion about the increasingly important role of the social innovation in tourism. It is going for the service design processes that form creative projects from different fields of tourism and provide employment opportunities to young people and senior citizens alike. In addition, an integrated service system of interdisciplinary knowledge, multistakeholders and local resources fulfils various requirements of stakeholders to promote sustainable tourism. Contribution – This paper aims to fulfil this gap by presenting the theoretical domain in which this topic fits in and evidencing those successful factors that should be considered when designing and implementing a social innovation in tourism which may help other firms or local communities in Croatia facing a similar process.

Purpose: This study aims to examine the evolution of the tourism supply chain (TSC) and its future development factors. To this end, a quantitative bibliometric analysis was conducted to provide insights from a statistical perspective, including the evolution of the TSC and an outlook on current characteristics and future research trends.Design/methodology/approach: This paper presents a quantitative bibliometric study of selected papers on the Web of Science. The study of the evolution of the TSC is based on analyses of bibliographic coupling and co-occurrence of keywords.Findings: Bibliographic coupling analysis identified 10 clusters defined by coherent groups of theoretical perspectives. The keyword analysis explains the occurrences in the TSC concept. It also helps to determine the future main drivers of TSC research. In the post-COVID-19 era, the tourism industry needs to focus on green transformation and new technologies to transform TSC, supply chain management and B2B relationships. It also needs to ensure employee retention and policies to attract new talent.Originality/value: This study provides a comprehensive, objective and integrative overview of the evolution of TSC. It is one of the few original works on supply chain development and will be helpful for scholars and practitioners alike to understand the subject.

The topic of cyber security in tourism is of particular importance since tourists in foreign countries are one of the most vulnerable groups due to a lack of knowledge of languages, laws, etc. With the increase in the number of technologies that enable interactivity, contactless payments, i.e., informative content for tourists, risks for the security of tourists' data as well as risks related to the theft of data on tourists' bank cards are emerging. In order to identify the current knowledge, i.e., the current situation in the context of research on cyber security in tourism, a bibliometric analysis was conducted, which indicated that an insufficient number of authors research cyber security and that there is not a sufficient number of studies that would analyze the mechanisms and measures of increasing cyber security in tourism. The importance of researching cyber security in tourism is based on the fact that tourism is a particularly vulnerable and sensitive branch of the economy to risks that affect tourists as such, and that it can depend on the reputation of the country, institutions, or hotels. The bibliometric analysis conducted in this paper is significant for future researchers considering that it can serve as a basis for researchers' focus on specific areas of cyber security.

Safety and security became a crucial component of an integral tourist product. Ability to offer tourists a safe stay during their holiday contributes to the attractiveness of a destination and its tourist product. Safety and security represent a pre-condition and a motive which many tourists consider crucial when choosing their destination for a holiday. Due to this, tourist destinations need to focus on improving the level of safety and security which will contribute to the satisfaction of tourists, and they will be more interested in visiting and revisiting a destination. Aim of this paper is to determine whether tourists consider safety and riskiness, as well as destination image as relevant factors in their decision-making process when choosing Opatija Riviera for their holiday. An analysis of the relevant scientific literature, and empirical research were conducted to determine if how tourists perceive safety and riskiness as well as the destination image when choosing to visit Opatija Riviera for a holiday. Based on the findings a discussion was developed to provide future activities of safety and security improvement.
