The purpose of this study was to examine the relationship between some elements of social capital, knowledge quality, and Small and Medium Enterprises (SMEs)’ innovativeness and export performance. Data were collected from owners/managers of SME exporters in Ghana. Structural Equation Modeling was used for the data analysis. The results indicate that the elements of social capital facilitate access to quality knowledge which consequently improves SMEs’ innovativeness. The study also shows that SMEs’ innovativeness affects their export performance.
