China's National Equities Exchange and Quotations, also known as the "new third board," saw the debut of 15 small- and medium-sized enterprises this week.
With the newcomers, the total number of companies on the board reached 11,079, according to the exchange.
From Aug. 6 to 10, turnover on the board stood at 1.51 billion yuan (about 221 million U.S. dollars), slightly down by 0.71 percent from the previous week.
The exchange was launched in early 2013 to supplement the Shanghai and Shenzhen stock exchanges to serve small- and medium-sized enterprises.
It is seen as an easier financing channel for small businesses, with low costs and simple listing procedures.
