National or international public funding? Subsidies or loans? Evaluating the innovation impact of R&D support programmes

The objective of this study is to compare the effect of different types of public support for R&D projects on firms’ technological capabilities. We distinguish be-tween low-interest loans and subsidies and between national and European sup-port. Using data on 4,407 Spanish firms during the period 2002-2005, we estimate a multivariate probit to analyse the determinants of firms’ participation in public R&D programmes and, later, the impact of this participation on firms’ technologi-cal capabilities using different indicators. The results provide evidence of the ef-fectiveness of all treatments for improving firms’ innovative performance. With respect to innovation outputs, apart from the indirect effect of public support by stimulating R&D intensity, we also find evidence of a direct effect of participation in the CDTI credit system and in the European subsidy programme on the probability of obtaining innovations and applying for patents
