BEIJING — China's securities regulator has given the green light to the registration-based initial public offerings (IPO) of four companies on the science and technology innovation board.

Maider Medical Industry Equipment Co Ltd, CHISON Medical Technologies Co Ltd, Luoyang Jalon Micro-nano New Materials Co Ltd and Primeton Information Technologies Inc will be listed on the Shanghai Stock Exchange's sci-tech innovation board, commonly known as the STAR market, the China Securities Regulatory Commission said in a statement.

It did not specify the total amount of funds to be raised.

The companies and their underwriters will confirm the IPO dates and publish their prospectuses following discussions with the stock exchange.

The STAR market, inaugurated in June and designed to focus on companies in the high-tech and strategic emerging sectors, eases the listing criteria but adopts higher requirements for information disclosure.
