The main goal of this research is study of government policies and related organizations in tourism industry in the third economic and cultural plan (because of its coincidence with its form, a functional system of policy making, resulting in the sustainable development of a country's tourism industry. The results of the research show that the policies of tourism industry in each of five-year plans namely the third development plan, have suffered due to lack of a model for predefined policy makings and specially lack of attention to basic policy making indices like centralization and coherence in goals, systematic, and integrated perspective among the policy makers, the extent of practicality of policies, and effective responsive system and a system for performance evaluation. Tourism development requires close consideration of development dimensions in all individual, organizational and national levels, and permanence of this development depends on utilization of resources, directing investments, orientation of technology development and a structural and fundamental change compatible with now and future needs of humanity. In this research, government policies in diplomatic, economic, cultural, and educational dimensions have been investigated. Tourism scholars believe that the path for achievement of sustainable development of tourism is feasible only through working on the following two groups:
- Primary indices of policy making apart from the subject of tourism.
- Professional branches of tourism
In the accomplished model the role and importance of any of the indices have been predicted. Moreover lack of a scientific basis in policy making resulted in consideration of this inefficiency in the model. The suggested model defines some goals at three levels: individual, organizational and national, and it is hoped that through fulfilling the goals of development in the above three; we may reach to a permanent development of tourism.
