Designing a model for the development of Iran's tourism industry with a sustainable development approach

The purpose of this study is to design a model for the development of Iran's tourism industry with a sustainable development approach. The statistical population in qualitative research includes experts and specialists in the tourism organization and in quantitative research, the staff of tourism organizations in Tehran and Mazandaran province. The sampling method is purposive in the qualitative study section and stratified in the quantitative random section. The method of data collection in this research is based on library studies, review of texts, relevant and field literature and data collection tools through interviews and questionnaires. Purposeful non-probabilistic sampling was used to select the interviewees, during which the experts tried to have practical experience in addition to theoretical knowledge. The validity of the measurement scale is based on "content-dependent" and "structure-dependent" and its reliability is evaluated based on Cronbach's alpha. In this study, Dalala test has been used to explain the structural relationships between the factors of development of Iran's tourism industry with the approach of sustainable development using the Demetel technique. The results show that according to the Dalala technique, the most important component is the competitiveness index from the experts' point of view. Also, based on the structural equation technique, it was found that all identified factors have a significant impact on the development of tourism industry.
