Using data collected from multiple respondents in all the business uni
ts of a large multinational electronics company, we examined the relat
ionships both among the structural, relational, and cognitive dimensio
ns of social capital and between those dimensions and the patterns of
resource exchange and product innovation within the company. Social in
teraction, a manifestation of the structural dimension of social capit
al, and trust, a manifestation of its relational dimension, were signi
ficantly related to the extent of interunit resource exchange, which i
n turn had a significant effect on product innovation.
