摘要：The concepts of social value creation and sustainability are acquiring a growing relevance in the vision shared by the tourism industry’s major stakeholders. Our aim was to determine a hybrid impact-value model capable of measuring tourism product sustainability through the use of indicators and the impact of stakeholder actions during the process of creating and generating products. An initial static vision of sustainability is complemented by a second dynamic vision, based on the measurement of value and change. The proposed model includes the same stakeholders, dimensions and indicators for both approaches. This standardization enhances the robustness of the model and its potential as an analysis instrument. After reviewing the considerable number of possible impact measurement techniques, we opted for the versatile methodology known as Social Return on Investment (SROI).
