Resumen
In the context of EU enlargement, was normal and record tourism market development and competition. But tourism market works best when no participant's able to dictate terms. Otherwise, market monopolization occurs causing regression, generating serious disputes and contradictions. Therefore it proceeds to adoption and use of special legislative measures at national and community to counter these trends. The role falls to the State to be the organizer of the optimal conditions for tourism market development through the application of economic laws and removing barriers, promoting basic levers of the tourism market: demand, supply and competition as a way of confrontation between the owners of tourist offers and market demand.
