To measure the social network capital, this paper proposes a measurement model composed of network size, network zenith, network range, network variety, and network density. This measurement model was tested with the CGSS 2003 and 2006 data using the structural equation modeling method. Good validity and reliability were obtained when this model was applied in the Chinese sociocultural context. Also, the Chinese NewYearGreeting Network was proven to be a valid instrument to measure the social network capital of the Chinese people.
