Voluntary service of Chinese enterprise employees shows the following characteristics：a relatively high participation rate，a fairly high loss rate of volunteers，a quite low frequency and very short duration of voluntary service. The high participation rate has a lot to do with the government’s large-scale administrative mobilization；the latter three characteristics，i.e.，the high loss rate of volunteers，low service frequency，and short service duration are caused by the absence of NPOs. In brief，the above characteristics of voluntary service by Chinese enterprise employees are mainly attributable to the absence of NPOs in the affiliated development mode under the low-welfare system.
