In a competitive business environment, the role of entities capable of exercising network governance (NG) has become indispensable to the operations of the companies involved. With few theories that approach the subject, this work has as its main objective the investigation of the background of network performance, trust and internal resources in the effectiveness of the NG, and its influence on the performance of the companies. To this end, 181 companies linked to the FIEMG-MG were surveyed in a quantitative and descriptive analysis in which multivariate statistical analysis was used to analyse the data. The results show that, on one hand, there is significant and positive influence of reliable records and internal resources on the NG, and on the other, working in networks does not seem to have much relevance. It emphasizes that, together, the antecedents can explain about 75% of the variability of NG. The positive influence of NG on the performance of the companies involved could also be seen.
