inserção do Rio de Janeiro na rede de conhecimento de petróleo offshore

Cities are the loci of the knowledge generation process, in a global production network context, as they bring together the wide variety of actors and assets required for such sophisticated activity. Knowledge generation involves the interaction between many actors located inside the city, such as firms, universities and research centers, and also between different cities’ actors, constituting a network form. However, not all cities manage to be part of this network, and literature has been focused on Global North cities and in high-tech industries. Considering these issues, this paper aims to map and investigate the knowledge network in the offshore oil segment, showing if (and how) Global South cities from resource-rich countries are inserted on it. We place this analysis at the city-level, locating the cities which appear as important knowledge generation places. To copy with these aims, we created a patent database, developed from USPTO granted patents between 2007 and 2017, designed a network based on inventors’ location, and applied the k-core analysis. We found out that Rio de Janeiro is the only city from a Global South and resource-rich country which appears in the most core layers of the network. We identified that Rio de Janeiro’s insertion is based on two groups of actors which play different roles, and that the city’s insertion in the network is highly influenced by the local NOC, Petrobras.
