Export and Innovation in SMEs and Large Firms: The main determinants

This study analyses the main determinants of exports and research and development (R&D) expenses of small and medium enterprises (SME) and large companies operating in Portugal during the period 2004- 2008. From a sample of 200 SMEs and 30 major exporting companies, the study uses a panel data analysis and fixed-effects and random-effects estimators to estimate the effects on exports and on R & D. Regarding exports, the study found a positive effect in terms of increased productivity and R & D in both SMEs and large companies. The results also suggest that SMEs that are owned by foreign enterprises export more than national SMEs. In relation to the determinants of spending on R & D, the study concludes that the increase in equity and net income has a positive effect on R & D spending in large companies, while in SMEs, increased expenditure on R & D is a consequence of increasing exports, whereas the increase in net income has a negative effect on R& D
