Abstr actNowadays tourism economy is driven by information technology (IT) and telecommunications. All tourism oriented companies, such as tour operators, travel agencies, rental agencies, cruisers and hotels experience the growing impact of what is commonly known as information and communication technology (ICT). Tourism sector represents the information-intensive industry characterized by a significantly long value chain influenced, to a great extent, by information. Its creation, collection, storage, retrieval and transfer remain within the core activities of all tourism enterprises. Every single innovation in IT sector can potentially change the strategy followed by tourism companies in running a business. Such transformations are also imposed by tourists' behaviors which keep altering under the influence of information technology. The process of tourist services purchase is based on information collected through many different channels, e.g. travel agencies, brochures, the word-of-mouth, or web sides offered by tourist service suppliers, which are currently gaining much importance. Consumer decision making process in tourism sector is transformed into an online one, since direct service booking has become possible. Proper understanding of behaviors presented by those searching for travel information online, as well as using innovative information and communication technologies by tourists, remain essential for designing an effective ICT-based business model. Currently it seems to be the crucial challenge for the entire tourism sector. ICT is focused on designing the new scientific paradigm (by innovation, co-opetition, collaboration with customers) of tourism development based on modern e-technologies. The paper discusses the level of information and communication technologies application in the tourism sector. The study covers small and medium-size hotels (SMEs) and travel agencies which dominate the tourism industry worldwide. The article draws experience from the tourism industry in one of the most popular tourist destinations in Poland − Lower Silesia.

The dynamic development of the sharing economy is clearly seen in particular, in the area of tourism in large cities. There is, therefore, an increasingly urgent need to study its impact on the functioning of cities, especially when they implement a sustainable development policy. Therefore, the need to study its impact on cities’ performances is more and more urgent, particularly, when they implement a sustainable development policy. This study discussed the influence of a sharing economy in tourism on city sustainability from the perspective of the Agenda 2030 goals. The main objective of the paper was achieved, thanks to in-depth analysis of the content of secondary sources. Results of the analysis were subjected to the synthesis process, using the tabular method. In Agenda 2030, when diagnosing the importance of this issue, one of 17 goals, i.e., goal 11, and 10 tasks within it, were devoted to the sustainable development of cities. The results of this study showed that sharing economy in tourism has an impact on the implementation of seven of them, but the direction of the impact is diversified. The domination of positive sharing economy (SE) effects was observed in the following areas: providing access to safe, affordable, accessible and sustainable transport systems for all (Target 11.2) and upgrading slums (Target 11.1), while the negative effects were noticed particularly clearly in implementing Targets 11.6 (reducing the adverse per capita environmental impact of cities) and 11.7 (providing universal access to safe, inclusive and accessible, green and public spaces).

Purpose The purpose of the paper is to identify the state-of-the-art of scientific research on externalities generated in cities by the sharing economy in tourism (SET) based on an extensive literature review. Design/methodology/approach This review detected benefits and costs of the SET in cities development described in the literature using the economic externalities theory approach. The SALSA (Search, AppraisaL, Synthesis and Analysis) research procedure was used to collect relevant academic articles. For findings, the qualitative and quantitative content analysis combined to make a critical analysis of selected papers was conducted. Findings Thirty articles devoted to the impact of the SET in cities were identified. Five topics that gained researchers’ attention were recognized: real estate market; transportation; quality of life and gentrification; entrepreneurship and innovativeness of citizens; and local budgets’ incomes. The studies that present externalities of development of the SET in a more complex way are extremely rare. Research limitations/implications Research limitations are related to the methods used. The subjectivism of the research is a limitation to possibilities to achieve similar results when analyzing the same set of papers by different researchers. The results then are not to be generalized. Practical implications The research reveals a list of problems with externalities of the development of the SET in tourism destinations. Those problems are to be solved by policymakers in cities. Originality/value This study identified the gaps of previous research on the impacts of the SET on cities’ development. The paper presented an original conceptualization of future research.

The purpose of the article is to identify the impacts generated in the cities by the sharing economy in tourism and the presentation of solutions appearing due to sharing economy development and implementation in particular cities. Contemporary cities are functioning in extremely dynamic conditions that are difficult to predict. In view of the globalising economy, progressive urbanisation, rapid changes in information and communication technologies, as well as social demographic, geopolitical and economic changes, new problems appear and solutions to them have to be implemented by cities. One of these phenomena that are relatively new and fast growing, and influence development of cities, is sharing economy (SE) in tourism. The greatest concern of the city authorities is fast and unrestrained development of services through global platforms in the accommodation and passenger transport industry, and the powerful global leaders of these markets – Airbnb and Uber have become very important partners for local governments, but also difficult ones. On the bases of extended literature review embracing scientific sources and industry reports it can be visible, that actions taken by the local authorities tend to be reactive not systematic and concentrated only on solving isolated current problems. It is postulated though that development of SE should be perceived in a way described by Hall (1994) as a third-order change. Several suggestions for future scientific research are also presented.
