The main objective of this research is to analyze the impact of business incubatorson the survival of their associated firms. Using a configurational comparative method, the fuzzy-set qualitative comparative analysis (fs/QCA), it also examines whether the degree of business innovation, size, sector of activity and export activity affect firm survival. One of the most notable conclusions from this analysis is that the survival of a firm is related with at least some of the following characteristics: the firm must be technology-based, its productive focus is on goods (rather than on services), or that it is located within the specific environment of A business incubator.
