BEIJING?-- China's electronic information industry expanded in 2015 thanks to technological innovation and policy, according to the Ministry of Industry and Information Technology (MIIT).

Total revenues of major electronic information companies, or those with annual revenues of more than 20 million yuan, are expected to hit 15.5 trillion yuan ($2.3 trillion) in 2015, double the gross revenues of 2010, said Huai Jinpeng, vice minister of the MIIT.

Innovations such as cloud computing, big data, and the Internet of Things are bringing opportunities to the sector, Huai said.

China's cabinet unveiled its "Internet Plus" action plan in July last year to shape the information technology and traditional sectors into a cohesive, efficient force.

Huai said the ministry will continue to improve Internet infrastructure in the next five years and make broadband Internet accessible in every corner of China to foster new engines for growth and upgrade the economic structure.
