Stock exchanges in Shanghai and Shenzhen Thursday released a revised set of delisting rules for mainland-listed companies in a bid to boost investor sentiment and promote the healthy development of the stock markets.

As the two exchanges had asked for feedback on an earlier draft proposal from April 29 to May 20, the new changes are all based on reasonable public opinion, the exchanges said in statements on their websites.

Among the adjustments are accounting and market trading indicators, which the exchanges say will determine a company's delisting in accordance with clearer standards.
