The report also said in the first six months, the Hong Kong and Shanghai bourses were ranked first and second globally, financing 103.4 billion yuan and 103.1 billion yuan, respectively, followed by the New York Stock Exchange and the London Main Board.

Edmond Chan, co-head of capital markets services at PwC Hong Kong, said: "The Shanghai-Hong Kong Stock Connect program has broadened the investor base in Hong Kong, increased the liquidity and trading volumes of both the mainland and Hong Kongstock markets, and increased the value of certain sectors, such as securities, media service and new energy enterprises."

Chan said that the mainland-Hong Kong mutual recognition of funds program is expected to further boost the flow of funds between the two places. The launch of the Shenzhen-Hong Kong Stock Connect later this year will definitely boost the performance of the Hong Kongstock market.

"As basic peripheral factors continue to improve, coupled with the steady growth of China's economy, we believe the Hong Kong market will be the international financing platform for more and more mainland companies," said Chan.
