Firm size, business experience and export intensity in SMEs: a longitudinal approach to complex relationship

The objective of the paper is to test the effect of firm size and business experience on export performance. In fact, despite a growing number of empirical studies, the question of the relationship between these variables is not clearly established. This research aims at contributing to a better understanding of these complex relationships with a special focus on small and medium-sized enterprises (SMEs). The authors develop a general model and test it using a sample of Italian manufacturing firms that spans the 1997–2001 period. Combining a time-series with a cross-sectional analysis, they use an econometric model in order to test the relationships. Their findings provide a strong support for both relationships. The results show that it is not business experience per se which is important but that it is the relative change in experience that truly impacts upon export performance. The model also reveals that industry effects are relevant.
