Shanghai to lead top-end office market by 2020

Shanghai is expected to replace Hong Kong as China's largest office market by 2020, with its top-end office stock surging 80 percent from the current level to 13 million square meters, a report said.

The report added there won't be a supply glut because demand will expand accordingly.

Although Grade-A office area in the nation's financial hub will nearly double by 2020, strong demand from such sectors as financial and professional services, healthcare and retail industries will be able to absorb the huge supply to keep the city's vacancy rate in single digits, the report said.
