The separated paths will also greatly increase the examination efficiency of M&A deals, enhancing resource consolidation while eliminating outdated production capacity, said the Beijing-based Securities Daily.

To facilitate the implementation of the new examination process, the CSRC has recently introduced a rating system evaluating the capacity of securities companies to act as financial advisors for public corporations' M&A deals.

Ten companies have been rated at the A level, including CITIC Securities Co Ltd, GF Securities Co Ltd, Guotai Junan Securities Co Ltd, and Qilu Securities Co Ltd. Observers believe that their clients have bigger chances of entering the exempt/fast path track.

Some of the A-level securities companies saw their A-share prices soar on Tuesday, with a 1.06 percent increase for CITIC Securities and a 1.18 percent rise for GF Securities.

Sixty-three M&A applications had been filed as of Sept 30, according to the CSRC, and 2,979 M&A cases in the A-share market are underway or have been completed since the beginning of the year, involving 973 listed companies and combined assets of 1 trillion yuan ($163.3 billion).

Meanwhile, several companies that have recently completed M&A deals have also seen large gains in their stock prices.

ZQGame Inc - an Internet company that bought 51 percent stakes in two technology companies at the end of September - has seen a 682.27 percent surge in its share price compared with the beginning of the year, while Huayi Bros Media Group, which purchased a stake of more than 50 percent in a Guangzhou-based mobile phone game developer in September, has seen a 450.55 percent hike in its stock price compared with the beginning of 2013.
