China's southwestern Guizhou province is aiming to lure worldwide big data companies with better government support and larger economic incentives.

"We will build Guizhou into a leader in big data innovations and applications in the next three to five years," said Wang Jiangping, deputy governor of Guizhou province, on Tuesday.

To achieve that goal, Wang said, the government has rolled out a slate of policies to attract big data enterprises, such as subsidies for renting offices, servers and tax rebates.

Currently, China's big three telecom operators -- China Mobile Communications Corp, China Telecommunications Corp and China United Network Communications Group Co -- are devoting 15 billion yuan ($2.4 billion) into constructing three big data centers in Guizhou, which are expected to house 2 million servers.

The three carriers promised Guizhou-based big data companies better Internet connection speed with lower prices.

Earlier this month, the State Council, China's cabinet, issued a guideline to boost the development of big-data-related industries. The guideline listed Guiyang, capital of Guizhou, as the nation's first big data pilot zone.

The province has already clinched deals with technological heavyweights such as Qualcomm Inc, Alibaba Group Holdings Ltd, Tencent Holdings Ltd and Foxconn Technology Group.

Local officials reported more than 1,200 big data companies established in the first half of 2015 in Guiyang.
