Sustainable Tourism Dynamics: Understanding the Impact of Tourist Stays on Regional Revenue and Development

Utilizing a dataset covering four Portuguese NUTS II regions from 2009 to 2022 and employing multiple regression analyses, this research challenges traditional tourism theories by providing empirical evidence on how various factors—average stay, overnight stays, and foreign guests—affect regional revenue in tourist accommodations. In the context of sustainable tourism development, these findings have revealed a significant negative relationship between average stay duration and revenue, indicating that longer stays may be associated with lower daily revenues. This necessitates a re-evaluation of tourist spending behavior and accommodation of pricing strategies to promote economic sustainability. This study underscores the consistently positive impact of overnight stays on revenue, reinforcing the importance of maximizing overnight stays as a strategy for sustainable economic growth within the tourism sector. Additionally, the mixed results regarding the proportion of foreign guests reveal varying regional impacts, suggesting that region-specific strategies are essential for optimizing revenue from international tourists in a sustainable manner. This research integrates these factors to offer practical insights for refining revenue strategies in tourism management, emphasizing the need for multifaceted theoretical models that account for the complexity of sustainable tourism dynamics. Future research should focus on these nuanced approaches to better understand and manage the interplay between tourism dynamics and sustainable development.
