Due to its size and complexity, Petrobras operations and activities have direct impact on the Brazilian economy and on the local supplier industry (equipment and services). From the perspective of accelerating the development of markets in which it operates, Petrobras investment projects and hiring processes should bear the challenges defined in its Strategic Plan and maximize the local content on competitive and sustainable basis, contributing to the improvement of Brazilian local content policy. This dissertation aims at evaluating the applicability of input-output analysis to Petrobras local content management practices, as a tool to assess the relationship between the Brazilian local content policy and social and economic impacts of implementation of investment projects in oil, natural gas and shipbuilding sector in Brazil. The research can be considered applied, methodological and descriptive. The methodology comprises: (i) bibliographical and documental review; (ii) field research, by consulting managers and experts involved in local content and corporate strategy areas; and (iii) a case study, including analysis of results and propositions for stakeholders. The main results are: (i) critical review of the literature on local content and input-output analysis; and (ii) Petrobras case study, illustrating the applicability and effectiveness of the methodological approach proposed.
