Listed companies and their underwriters should both take responsibility to ensure information transparency, which is the key to protecting investors' interests, then the A-share market can be changed from its current role as a "cash dispenser for big enterprises", the researcher added.
In addition, the revision of the law will expand the business scope of securities firms and reduce administrative approvals for domestic companies to issue securities overseas.
Too much administrative intervention in the market is seen as the main factor distorting stock prices, which ultimately harms small and medium-sized investors, said experts.
Discussion about the reform has been going on for years, but no substantial progress had been made before the revision of the Securities Law.
This law was first introduced in 1998, clarifying the basic regulatory system for the stock market for the first time since the Shanghai Stock Exchange opened in 1990.
In October 2005, the NPC Standing Committee announced a comprehensive revision of the law, adding a sponsor system to take responsibility for listed companies' behavior.
The committee also revised provisions of the law in August 2004 and June 2013.
As the economic environment has changed a lot, further revision of the Securities Law is necessary as an important part of the overall national financial reform toward a more market-oriented system, said Xin Chunying, vice-chairwoman of the NPC Legislative Affairs Committee.
"There are some international rules for drafting securities laws, but they are not yet reflected by the law in China, as the market is not mature," she said.
The core concept of the Securities Law should be investor protection, Xin said.
CSRC Chairman Xiao Gang, in an article on the commission's website, said that policymakers are considering launching a public lawsuit system for the security market, under the framework of the revised law.
This means there would be a special organization to initiate public prosecutions when individual investors suffered losses from illegal activities including disclosing false information, insider trading and market rigging, the official said.
Any mechanism that hurts market fairness and justice, or tends to trigger regulatory arbitrage or lead to systemic financial risks, should be improved. Such problems need to be solved through the law revision this time, said Xiao.
