The manufacturing hub for the electronics industry, Kunshan, in Jiangsu province, is seeking a drastic reduction in labor costs as it undergoes a makeover after an industrial explosion killed 146 people in 2014.

The county, one-seventh the size of neighboring Shanghai and the mainland's first county to achieve US$4,000 per capita income, was adjudged the best county for its economic performance by Forbes for seven years in a row. However, the blaze, blamed on poor safety standards and haphazard industrialization, dented Kunshan's pride. More than a year on, the county, which attracts much of its investment from Taiwan, is trying to reinvent its growth strategy. It is accelerating growth by replacing humans with robots and encouraging start-ups. Thirty-five Taiwanese companies, including Apple's supplier Foxconn, spent a total of 4 billion yuan (HK$4.74 billion) on artificial intelligence last year, according to the Kunshan government's publicity department.

"The Foxconn factory has reduced its employee strength from 110,000 to 50,000, thanks to the introduction of robots. It has tasted success in reduction of labor costs," said the department's head Xu Yulian.

"More companies are likely to follow suit." As many as 600 major companies in Kunshan have similar plans, according to a government survey. The job cuts do not augur well for Kunshan, which had a population of more than 2.5 million at the end of 2014, two-thirds of whom were migrant workers. Factories and other buildings cover about 46 per cent of the land – a figure which is far higher than the cap set by the central ­government.
