Zusammenfassung:
In a context where tourism is recognised as a key driver of eco nomic, social and territorial development, the question of how to effectively measure its economic impact is becoming increasingly important. A reliable and nuanced assessment is essential not only for recognising tourism's contributions, but also for guiding strategic decisions that ensure the long-term sustainability and resilience of the entire system. Traditional analytical tools, such as Input-Output models, Tourism Satellite Accounts (TSAs), Social Accounting Matrices (SAMs) and Computable General Equilibrium (CGE) models, provide useful estimates, but tend to simplify complex dynamics, especially in local contexts. This study adopts a qualitative exploratory approach to analyse the gap between existing models and the information needs of actors in the tourism sector. Based on semi-structured interviews with professionals working in tourism, the research investigates three central questions: what are the current practices for data collection and use? What economic information is lacking to support operational and decision-making activities? And how could the information system evolve to be more consistent with the complexity of the tourism phenomenon? The results show methodological and operational difficulties in information management, including fragmentation of sources, complexity in comparability, resource constraints and interpretative ambiguities. At the same time, there is a strong demand for more relevant, up-to-date monitoring tools, co-designed with local stakeholders and capable of integrating quantitative and qualitative dimensions. The discussion proposes to move beyond top-down approaches and promote collective territorial intelligence, where the information system is built through collaborative governance, oriented towards the strategic use of data and the sustainability of tourism policies.
