Lin's research interest lies in
social networks,
social support and
social capital. He has contributed theory, devised measurements and conducted empirical research in each of these areas. He has applied the theory and measurements to the study of
social stratification and
mobility,
stress and
coping, and individual, organization and community
well-being. Lin has employed both
quantitative methods—such as large-scale national surveys, and surveys in organizations and communities—and
qualitative methods, such as intensive long-term observations in villages, for example. Having written about
social networks since the early 1980s, seeking to establish a research paradigm which integrates theory with empirical testing. His definition of social capital as access to resources through network ties is one of the most widely accepted conceptualizations of the term. This definition of social capital is quantifiable and widely held to be more precise than the one popularized by
Robert Putnam. Lin also rejects Putnam's thesis, put forward in
Bowling Alone, that social capital is decreasing; he maintains that it is, in fact, on the ascent thanks to increasingly pervasive online networking. ==Honors and awards==
