Estrutura Tecnológica E Mudanças Climáticas No Brasil: Um Estudo Exploratório A Partir De Estatísticas De Patentes

This paper analyzes the evolution of the Brazilian technological structure in areas with potential to mitigate climate change in the post-Kyoto period. From the creation of an original database with patents related to climate change, the paper proposes an interpretation of the changes occurred in the technological specialization of the country and the evolution of its performance compared to selected countries. The Technological Revealed Comparative Advantage estimation showed that the country did not follow the international dynamics and reduced its number of areas of technological specializations. The structural decomposition analysis revealed that the increase in the Brazilian share of the world’s patenting activity is explained mostly by the technology share effect, that is, by the part of the growth which is due to the dynamism of its patenting activity. The country abandoned stagnant areas, and the results would be even more favourable if it had a better structure of specialization in the initial period.
