Thanks to the huge fundraising by three companies from Chinese mainland - China Tower, Xiaomi and Meituan-Dianping, Hong Kong has topped the list for global IPO volumes this year, said Deloitte China recently.

China Tower, Xiaomi, Meituan-Dianping, Ping An Healthcare and Technology and Jiangxi Bank ranked the top five in fundraising at Hong Kong's IPO market this year, with a total financing of HK$151.9 billion ($19.4 billion), up 157 percent compared with a year earlier.

Major reform of the city's listing regime, which welcomed dual-class share structure firms and pre-profit biotech companies, contributed to its stellar result this year. New economy companies, including those in technology, education, pharmaceutical and pre-revenue biotech, are likely to attract the greatest market attention in 2019, according to Deloitte.

Here are some representatives and their net proceeds from global IPOs.
