Willingness to pay for social health insurance among informal sector workers in Wuhan China: a contingent valuation study

摘要

Background Most of the about 140 million informal sector workers in urban China do not have health insurance. A 1998 central government policy leaves it to the discretion of municipal governments to offer informal sector workers in cities voluntary participation in a social health insurance for formal sector workers, the so-called 'basic health insurance' (BHI).
