Evolução da rede de copatenteamento em tecnologias verdes: uma análise de 1997 a 2016

Abstract

Considering the existing barriers to the development of Green Technologies, the collaboration between inventors arises as a useful tool. Once the structure of the network of collaboration formed between agents has a direct influence on the results obtained individually and for the group as a whole, this work has the objective of analyzing the evolution of the structural characteristics of the Green Technologies co-patenting network formed by different countries, during the period 1997-2016. For such, the methodology chosen was the Social Network Analysis, that allowed analyzing the network visually and also quantitatively. The results point out that the network grew in terms of countries and ties formed between them. In all the periods, the network presents a structure very centralized in a small group of main countries, in which United States, Great Britain, Germany, France and Canada stand-out. Emerging countries such as India and China deserve attention for their evolution over the analyzed period, once they achieved, in the last periods, very central positions in the network.
