Oliver Barron, an analyst in Beijing with North Square Blue Oak Ltd, a UK-based investment bank, said the Internet industry will play a bigger role in China's economy.
However, it is still too early to say how much it has boosted the country's economy, he said.
China's GDP was 47.2 trillion yuan in 2011, and according to the government's full-year target of a 7.5 percent growth rate, which is due to be announced this Friday, is likely to have reached 50.74 trillion yuan last year.
That means the Internet industry is the source of 0.9 percent of the total GDP in China.
Barron added that in the past two quarters, the property sector was the real booster of the country's growth, which has been affected by a shrinking demand from overseas markets for its exports.
Outside China, Internet companies continue to drive growth and job creation in the IT industry, according to a report from the Organization for Economic Cooperation and Development in October.
The top 250 companies in the information communication technology sector by revenue boosted employment in OECD countries by 4 percent in 2010 and 6 percent in 2011, the report said.
The IT services industry bucked the 2009 economic downturn better than manufacturing, and rebounded in early 2010, the report said.
