ABSTRACT
This paper investigates some basic aspects about the traditionally used definitions and classifications of service activities. The first part of the paper evaluates some essential transformations concerning service activities, which are occurring in the productive processes, in the nature of the product, in consumption and in the market, since the advance of recent technological innovations. It stresses the difficulty to measure and analyze those recent economic evolutions, by using the traditional conceptions. Following, it proposes a revision and up-dating of the concepts, in order to adapt them to the new role performed by this sector in the worldwide productive context.
