The central government will continue next year to push for companies to carry out dual listings in Hong Kong and the mainland, according to a report. At the same time, Chinese companies already listed on the Hong Kong Stock Exchange will be encouraged to make their stock available in the mainland through A- share listings, the China Securities Journal reported yesterday, citing Yao Gang, an assistant chairman with the China Securities Regulatory Commission. The commission would study ways to bring red-chip companies in Hong Kong back to the A-share market, said Mr Yao, who was speaking at the Shenzhen Stock Exchange where he met with sponsor institutions, according to the report. Of the 132 mainland companies listed and traded on the Hong Kong Stock Exchange, 37 have already issued A shares, including most recently Datang International Power Generation and Guangshen Railway. Mr Yao said the primary market for stocks in China has improved a lot since May, when companies were allowed to raise money in the stock market following a ban while share reforms were introduced. The government launched the reforms last year to make all non-tradable shares tradable on mainland exchanges. Listed firms were split into different batches to undergo the reform and the most recent batch of 22 companies to be reformed is the 63rd and last for this year. About 95 per cent of all companies that have to undergo the change have already started or completed the procedures, government statistics show. More than 70 companies have been listed on the Shanghai or Shenzhen stock exchanges this year, while 52 listed companies have issued more shares to raise money. Together, this added more than three trillion yuan to the market value of domestic stock markets. The total market value of Shanghai and Shenzhen stock markets now amounts to more than eight trillion yuan, 1.5 times more than at the end of last year.
