A survey by the Shanghai labour authorities found that experienced technicians in the city earn incomes similar to employees in more sought-after office jobs, Xinhua reported. The best paid are those in high- and newtechnology sectors such as communications, electronics and motor vehicles, where workers can earn up to Yn100,000 a year. Technicians in some traditional industries, such as locksmiths, pattern-makers and oil refiners, can make up to Yn80,000. Those in the service sector such as hairdressers and chefs can earn up to Yn50,000, still considered a decent income in China. Only 3.5% of China's 70m technical workers are classed by the Ministry of Labour and Social Security as 'advancedskilled workers', compared with about 40% in most developed countries. The ministry aims to increase the proportion to 20% by 2005.
