Attractiveness is an important element in the development of a region, because it helps to put it at the forefront of the competitive scene, and makes it like a product that needs to be sold in order to develop. Indeed, it is seen as imperative for all countries. This is facilitated, in particular, by the adoption of a territorial marketing strategy that enables the region to highlight its assets and promotes development through territorial marketing actions. We therefore believe that there is a relationship between the practice of territorial marketing and regional development. Throughout this work, we will try to demonstrate this relationship by focusing on the contribution of the tourism sector.
