The Beijing Stock Exchange on Friday unveiled rules for margin trading and securities lending to prepare for the start of such businesses.

The new businesses will help meet investors' diversified trading demand, improve the pricing function of the market and boost market liquidity, according to the bourse's online statement.

The rules are generally in line with those of the Shanghai and Shenzhen stock exchanges, which have already launched their businesses.

The margin deposit should be no less than 100 percent in margin trading, and no less than 50 percent in securities lending, the bourse said, adding stocks in public companies, equity funds, bonds and money market funds can all be used as deposits.

As of September 2, 110 companies were listed on the Beijing bourse, with a combined market value of nearly 200 billion yuan ($28 billion).
