Bibliometric analysis of international researches on innovation metrics

This bibliometric study aims to identify the state of art of international bibliography related to innovation metrics theme. This paper discusses several intents in measuring innovation through metrics and models due to the fact that innovation occurs in a more contextual way and formed by multi-faceted indicators that go beyond a rigid measure modelling. Using the period of the last ten years and Boolean searches for key terms in Web of Science databases, we selected 136 papers that were captured by EndNote Web. Results were analysed through two phases: the quantitative results were sorted in descending order and we noticed a publication increase during the studied period. The journals that gather the bigger number of selected publications were Research Policy and Technovation. The second qualitative analysis categorised selected papers after reading all abstracts and we found that the metrics that appeared the most are number of patents, performance, innovations in product and process, inputs and outputs, innovative activities and capabilities, R&D, and firms' structure and interactions.
