This paper explores the dynamics of social capital in 121 new foreign market entries (FMEs) of 24 Swedish and New Zealand small- to medium-sized enterprises in the early and later phases of their internationalization. Its main contribution is the systematic assessment of the roles and forms of social capital over time and across countries, thus providing greater insight into the social capital concept. We separate social capital into efficacy and serendipity roles (economic dimension) and direct and indirect relationships (structural dimension). Efficacious and direct social capital is associated with early FMEs, while serendipitous and indirect social capital is more prevalent with later FMEs, indicating that social capital changes with (and is dependent on) FME. Moreover, while geographical proximity does not appear to affect the economic dimension of social capital, it is important for the structural dimension.
