It Pays to Have Guanxi: How Social Capital Affects Household Income in China

Abstract

The association between social capital and household income receives inadequate attention over the past decade. We examine the role of social capital in household income using three waves of household surveys from 2011 to 2015 in China. Using ``local big surname or not" as the instrumental variable, we find that gift expenditure as a proxy for social capital is positively associated with total household income. In addition, social capital mainly affects income sources through improved financial sophistication, higher job position levels, closer government connections, and greater accessibility to operating loans. The results are robust to alternative social capital measures. The findings highlight the importance of social capital in household economic welfare in China.
