In this paper we evaluate statistically how the R&D management of a firm in terms of speed of research, exploitation of knowledge in the scientific journals and research focusing affects research quality in terms of (forward) patent citation. We extensively control the endogeneity of explanatory variables in our estimation. We find that higher speed of research measured by (backward) citation lag and stronger science linkage significantly improves patent quality, research focusing tends to improve it, and there are significant differences in the effects of these variables on the R&D performance across technology areas and between US and Japanese firms.
