A total of 28 new small and medium-sized enterprises debuted on China's National Equities Exchange and Quotations (NEEQ), also known as the "new third board," in the past week after the week-long holiday.

The newcomers brought the total number of companies on the board to 11,608, data from the NEEQ showed.

Turnover on the board stood at 3.14 billion yuan (about 476 million U.S. dollars) last week, down from 4.82 billion yuan the previous trading week.

Chinese markets were closed in the first week of October for the National Day and Mid-Autumn Festival holidays.

The NEEQ was launched in early 2013 to supplement the Shanghai and Shenzhen stock exchanges in serving small and medium-sized enterprises.

It is seen as an easy financing channel for small businesses with low costs and simple listing procedures.
