China's Internet companies are thriving, basking in the glow of a significant Internet boom.

The 37 globally listed Chinese Internet companies saw their revenues surge 38.7 percent year on year in the second quarter, compared with 36.7 percent in the same period of 2010, according to a recent report by China Venture, a Beijing-based investment consulting firm.

The best performers were video sharing companies and social networking websites, which experienced 118.4-percent and 68.6-percent growth in revenues, respectively. Portal websites and e-commerce firms also fared well, with revenues growing 45.7 percent and 23.9 percent, respectively.

Despite the market buoyancy, eight of the 37 firms spilled red ink, including the online bookstore Dangdang and video sharing websites Youku and Tudou.

China now has the world's largest Internet market, with user population totaling 485 million at the end of June 2011.

If Chinese Internet companies continue with strong performances, investors' enthusiasm may be boosted again and the listing of Chinese Internet firms on the U.S. stock market is likely to resume in the fourth quarter, said the report.

Nasdaq-listed Tudou was the only Chinese firm that went public overseas in August.
