The purpose of this paper is to assess the cost-structure of the public transport industry in Tunisia. Thus, we use a translog variable cost function to identify the firms’ technological features. In this analysis, we work on a sample of 12 Tunisian regional transport companies (RTC) over the 2000/2010 period. The main results show the critical productive situation of the urban public transport system in Tunisia. This can be exemplified by the presence of a short and long term diseconomy of scale, given that the overall factor productivity is low and almost zero.
