Application of Environmental Principles and Innovations in Tourism in V4 Countries

This article summarises the arguments and counterarguments of scientific discussion on the adoption of green innovations by tourism enterprises in V4 countries, with a specific focus on the simultaneous influence of regulatory stimuli, product demand, and enterprise size. The primary objective of this research is to identify and examine the determinants of the implementation of environmental measures in the tourism sector, as well as to quantify their interrelationships. The systematisation of literature sources and approaches to address this issue indicates that most existing studies have a national focus and lack comparative cross-country research that integrates policy, market, and business factors. The relevance of this scientific task lies in the fact that transitional economies often fail to recognise the synergistic effect of these factors, which may hinder the successful adoption of green tourism. The research follows a logical sequence: theoretical background and literature review, clarification of methodology, presentation of empirical results, comparative explanation, and formulation of conclusions and policy implications. The methodological framework combines quantitative survey techniques with multiple regression analysis applied to tourism enterprise data within the V4 region. The object of the study comprises tourism enterprises in V4 countries, which operate under differing policy and market conditions yet face similar sustainability challenges. The empirical findings confirm that legislative incentives and consumer demand are the principal drivers of environmental measure implementation, whereas enterprise size serves as a significant moderating factor. These results empirically support and theoretically reinforce the necessity of complementary policy and market measures to achieve sustainability in tourism. The study extends existing knowledge by demonstrating the interplay between regulatory frameworks, market demand, and business characteristics in shaping sustainability practices. The findings are of practical relevance for policymakers, tourism organisations, and entrepreneurs in designing targeted policy instruments, optimising incentive schemes, and removing administrative barriers. Furthermore, the study highlights the need for further longitudinal and cross-regional research to monitor changes over time and explore the role of digital technologies as enablers of sustainable innovation in tourism.
