This work is a tribute to the 20th anniversary of the Revista de Ingeniería de la Universidad de los Andes. In these two decades this journal has guided the construction of social capital of this School of Engineering. This work presents the relationship between the scientific production of the School of Engineering and its accumulation of social capital. Social capital is represented by coauthorships. These relations represent a dynamic network where groups of actors work together in the production of knowledge. The proposal is that structural characteristics (size and connectivity) of the network represent a measure of social capital. Therefore, the study of the dynamics of the network gives hints of the accumulation of social capital and the collective strategies of knowledge production. The results show a dose-response relation between scientific production and the structural characteristics of the network. The connectivity between coauthors and the size of the network (number of nodes and number of arcs) are positively related with the dynamics of knowledge production.
