The list, which was announced at the Second Annual China International Service Outsourcing Cooperation Conference in Nanjing late last month, features the top ten revenue generators of last year.
WuXi, which posted revenue of $256m (€183.7m) in 2008 thanks largely to gains made by the integration of AppTec into its laboratory analysis business, was the only contract research organisation (CRO) to make the top ten.
The Chinese government, which has been actively encouraging the growth of the outsourcing sector for a few years, estimated that it was worth some $1.5bn in 2008, up around 34 per cent on the previous year.
