Through this study we aim at performing an analysis of the concept of local interest, having as prerequisites the doctrinal debates regarding the general interest. The examination of this concept occurs in relation with the new trends, as concerns the exercise of competences at local level, respectively with the elements that define the interest of the community and its means of application within the life of the local community. Our research aims to establish theoretically the notion of local interest, an approach that we carry out within a difficult environment, whereas the notion of interest is fluctuating, being constantly modified under the pressure of the evolutions of social and economic needs. The results and the essential contribution of the material consist in the establishment of a framework that would offer to local authorities the practical possibilities for identifying the landmarks that surround this concept and that has to be harmonised with the values of modernity in order to respond better to the needs that are expressed.
