Tech firms are the most favorable candidates among US investors. China's Web fever has helped boost evaluations of Internet companies.

The nation had more than 590 million Internet users as of June, accounting for nearly half of the total population, according to China Internet Network Information Center.

The number of China IPOs slumped dramatically after a series of Chinese companies' financial scandals disrupted Wall Street's confidence in 2011.

Chinese companies have raised about $171 million on Wall Street this year. The amount was above $4 billion in 2010, data from financial service platform Dealogic showed.

The small number of Chinese companies listed after 2011 were "doing well", according to Lau. The companies saw their values surge by up to 10 times after an IPO because their initial evaluation was only 60 percent of the actual value.

A passive economic outlook and negative attitude toward Chinese companies created low evaluations.

In addition, Lau said the e-commerce giant Alibaba Group Holding Ltd's potential US IPO will also give momentum to other local companies that are eyeing a US listing.

However, Chinese companies have to survive attacks from short-selling firms after their IPOs, analysts warned.

Last week, the market cap of New York-listed NQ Mobile Inc, a Beijing-based smartphone security company, almost halved after a US short-selling company said NQ was marking up its market share.
