Abstract

This paper analyzes the effects of the evolution of knowledge base in the manufacturing sectors on regional productivity growth. Knowledge is viewed as a heterogeneous asset, and an evolutionary perspective is adopted. The results of the empirical estimations corroborate the hypothesis that beyond the traditional measure of knowledge stock, knowledge coherence and variety matter in shaping productivity dynamics. The check for spatial dependence suggests that cross-regional externalities exert additional triggering effects on productivity growth, without debasing the effects of knowledge. Important policy implications stem from the analysis, in that regional innovation strategies should be carefully coordinated so as to reach a higher degree of internal coherence and exert positive effects on productivity.
