The purpose of this essay is to check what are the effects of strategies and relationships in productive arrangements over the value chain of companies that participate in the City of Maringá’s Exportation Consortium and in the City of Apucarana’s Sectorial Integrated Project, from the clothes manufacturing field and located in Northern Paraná. Data collection was made by means of semi-structured interviews, non-participant observation and document analysis. Data treatment was descriptive-qualitative. To characterize analytical categories and find their effects, document and content analyses were used. The analyzed data reveal that in both cases the companies’ strategies are independent from the productive arrangement’s strategy. However, the relationships between the companies and the territory, that are part of the arrangements are important sources of information and search for improvement, both collective and individual; they assure better negotiation conditions, once they allow cost reductions; and noticed that the companies are trying to guarantee their national and international market share.
