Tourism in recent years on a global level recorded growth of international tourist arrivals, and consequently the income from tourism activity. Such constant growth in tourist traffic resulted in the diversification of the tourist product and the emergence of special interest tourism. Electronic dance music festivals are part of event tourism which is a part of human based special interest tourism. Electronic dance music festivals have become one of the most successful forms of tourism among younger audiences due to the fact that 1.5 billion people worldwide listen to electronic dance music. Compared to other music genres, fans of electronic dance music have the biggest habit of going to concerts and festivals, while the organization of such festivals generates significant economic impacts on the destination. The question that is the focus of the dissertation is how and to what extent the tourism demand for electronic dance music festivals affects the economic impacts on a destination in the Republic of Croatia. The theoretical part of the paper begins with an overview of special interest tourism forms and their classification based on resources. Based on the definition of special interest tourism, the general theoretical principles of event tourism (as a type of special interest tourism), the concept and determinants of tourism demand are introduced. One of the most important factors of tourism demand is the motivation of visitors. Understanding motivation is an essential part of tourist behavior because it answers the question of why people travel. By analyzing tourist demand and the problem of defining and measuring the effects of electronic dance music festivals, the variables used in the primary research were created. The primary research was conducted on a sample of visitors at the Ultra Europe Music Festival and the Hideout Festival, which took place in year 2022. in Croatia. The focus of the primary research is the analysis of the influence of demand for electronic dance music festivals on the economic impacts on tourist destination in the Republic of Croatia. The results of the conducted research confirm that the main observed variables in the structure of demand for electronic dance music festivals are statistically significantly different from the variables in the structure of tourist demand in Croatia. The conclusions are particularly significant in the variables such as age, average daily consumption, country of origin and means of transport. Contrary to expectations, further analysis revealed that music is not the main motive for participation in tourist activities among visitors at electronic dance music festivals. The factor analysis carried out on a sample of visitors concluded that motives associated with fun and dance are dominant and the most important motives for coming to the festival. Also, it has not been proven that there is a statistically significant difference in the observed physical economic impacts of the total number of arrivals and overnight stays in the destination depending on the three observed time periods around the date of the electronic dance music festival held in Croatia. However, the results of the research regarding the financial economic impacts showed that the organization of the electronic dance music festival generates significant financial economic impacts in the destination. The applied findings of the conducted research, in addition to theoretical ones, also have wider practical implications that are of key importance for making strategic decisions, both for the organizers of the electronic dance music festivals and for the local community in the destination. The conducted research has provided answers to many questions, but has also opened new opportunities for the future research in this complex, and to this date insufficiently researched field.
