The Relationship Between Firm Size and Innovation Activity: A Double Decision Approach


  • Ester Martinez-Ros
  • Jose Labeaga


The main purpose of this paper is to analyse the relationship between firm size and innovation activity using Spanish data at firm level corresponding to the manufacturing sector for the period 1990-93. This exercise is different to previous applications because we allow for different size effects in the decision to innovate and the innovation count equation, in the context of a double-hurdle approach. Several tests confirm the hurdle negbin model. We find that firm size is a relevant factor, although size effects are different in both decisions. A robust result from the different specifications estimated is the rejection of the Gilbert and Newbery hypotheses. We find out that the behaviour of firm size is neither linear in the decision nor in thc count equation. We also provide additional, and sometimes different, evidence to previous Spanish studies on R&D.
