A Spatial Analysis of the R&D‐Productivity Nexus at Firm Level

The aim of this paper is to evaluate the effect of research and development (R&D) on productivity by taking into account productivity spillovers. To this end, by using a sample of Italian manufacturing firms over the period 2004–2006 provided by the Xth UniCredit‐Capitalia survey (2008), we have analyzed the role of R&D in firm productivity by using a spatial autoregressive model. In so doing, we have allowed the productivity of each firm to be affected by the productivity of nearby firms. Results show that R&D significantly affects Italian firm productivity and that productivity spillovers across firms matter. Moreover, productivity is found to be positively affected by intrasectoral R&D spillovers, while intersectoral R&D spillovers do not have a significant effect.
