The first phase of the Hetao Innovation Hub has seen two wet laboratory buildings fully leased with about 90 firms signed up as of the end of May.
Permanent Secretary for Innovation, Technology and Industry Kevin Choi Kit-ming said on Saturday that virtually all floor space in the two buildings had been leased out.
Mainland Chinese companies accounted for 51 per cent of the tenants while local enterprises made up 35 per cent and overseas firms 14 per cent.
About 10 of the tenants were listed corporations and around 70 per cent were start-ups. The overseas tenants included companies from South Korea, Switzerland and Finland.
The hub forms part of the Northern Metropolis megaproject and the Hong Kong-Shenzhen Innovation and Technology Park in the Lok Ma Chau Loop.
