| Abstract: |
Based on the Knowledge Production Function framework given by Griliches
(1979), we slightly modify it so that the innovative output depends upon a set
of factors related to the firm internal characteristics and are influenced by
the environment. Specifically, regarding the firm internal determinants the
effect of the concentration of the ownership, the composition of the boards of
directors and the effect of the nature of the ownership (foreign and public)
are analyzed. Additionally, in order to capture the determinants of the
environment in which the firm operates other variables concerning the
internationalization of market, the agglomeration economies and the regional
knowledge externalities are also considered. In order to assess the impact of
these determinants on the number of patents and models of use awarded by the
firm, the discreteness of the latter variable has to be taken into account. We
apply Poisson and Negative Binomial models for a more comprehensive evaluation
of the hypothesis in a panel of Spanish manufacturing firms. The results show
patenting activity is positively favoured by being located in an environment
with a high innovative activity, due to the existence of knowledge spillovers
and agglomeration economies. |
