Purpose This study aims to seek to analyse the relationships between profitability, productivity, external debt and growth in SMEs. The authors also analyse firm size and age as explicative variables of small and medium-sized enterprise (SME) growth. Design/methodology/approach In this paper the...

This article shows new empirical evidence concerning the growth determinants of SMEs. Specifically, we identify the existence of a quadratic relationship between the level of intangible assets of Portuguese SMEs and their growth. Based on the results obtained here, we conclude that intangible...

Based on a sample of Portuguese SMEs for the period 1999–2006 and using two step estimation, namely probit regressions and dynamic estimators, this study makes two important contributions to the literature: (i) identification of a quadratic relationship between R&D intensity and SME growth...
