SUMMARY The main aim of this doctoral thesis is to empirically determine both the basic scope and the essential factors required of governing bodies that are responsible for defining and executing policy and strategy of rural tourism destinations in their initial phase of development, so that they can not only attain, but also maintain, a sustainable competitive position. It is also of vital importance that such models are defined and managed with the close collaboration of the local community of the tourist destination. Research has been carried out to establish the degree of perception residents of a particular tourist destination in the interior of the Valencian Community have regarding the economic, social and environmental impacts of tourism. This perception determines their attitude towards tourism development, which at the same time varies depending on the how close their profession is to the productive process of the tourist activity in that area. Methodologically, the most important criteria in the various fields of knowledge relating to competitiveness and tourist development are analysed. This helps us to establish the dimensions and factors that determine sustainable and competitive positions in the management of tourist destinations. Next, a questionnaire is put together and directed at managers who are experts in local tourist development, in order to check the validity of all analyses presented. According to the results of these analyses, the best way to tackle the competitive management of rural tourism destinations in their initial phase of development is to focus on, analyse and consider the key success factors, i.e. efficiency, quality and strategic positioning. These factors require an integrated and holistic focus in order to achieve their maximum operating effectiveness. Similarly, a sustainable competitive position will only be achieved when governing bodies responsible for defining and executing policy of rural tourism destinations select the correct strategy tool. Also, the necessary distinction should be made between the general policy governing the municipality as a whole and the strategy followed to manage the tourism destination as a market product. In this way, the managing entity - which should be integrated by representatives of public management – should be separated from private initiative and the local community.
