On the other hand, a second connotation refers to an increase in size or in quality and is seen as the result of a development process similar to a biological process, where a series of internal changes leads to an increase in the size and to a change in the characteristics of the growing object. [...] For the ordered model, we establish the order of the categories as follows: Mediocre ≺ Average ≺ Growth ≺ Profit ≺ Star where ≺ denotes the direction of the order relation: if a ≺ b, then a is considered a situation inferior to b. The order of these situations can be justified by the results of Davidsson et al. [...] First, it is possible to measure the impact of a firm’s position in a category at time t − 1 on the probability of being in a category at time t. This will be given by the estimation of coefficients Ѕit − 1. This is the dynamic aspect of the model represented here. [...] The various aspects arising from this study’s model represent the significant contributions of this work as they allow us to examine in greater depth the performance of the SMEs and the link between a firm’s growth and profitability. [...] We note that the proportion of firms in the Profit category at time t − 1 and in the Star category at time t is much higher than that of firms in the Growth category at time t − 1 and in the Star category at time t (nearly double).
