Zhang Feng, chief engineer of the Ministry of Industry and Information Technology, said at a meeting on Wednesday that China will establish a national big data center to promote the trans-departmental, trans-regional sharing of basic data, in order to improve the practical value of data and its efficient use.

Meanwhile, the authorities will enhance their supervision and surveillance of data, and strictly crack down on illegal practices such as data leaks and the selling of personal information.

Zhang said that the ministry will first promote the openness and sharing of data in sectors such as credit, transportation, health and employment. Meanwhile, the ministry will develop a roadmap for industrial big data, and promote the integration of big data with the manufacturing industry.

In addition, the ministry will also enhance the protection of data during its collection, storage, application and sharing and accelerate the drawing up of regulations for telecommunications and internet data management.

Studies show that China's data increases at a rate of more than 50 percent a year. It is expected that China's total amount of data will account for 21 percent of global total by 2020.
