From January to April this year, the growth rate of the added value of Xi'an's industrial enterprises above a designated size - those with annual revenue of 20 million yuan ($2.85 million) or more - reached 3.4 percent, ranking first in nine national central cities and 15 sub-provincial cities.

The figures were released at a news conference, themed around accelerating the growth of the advanced manufacturing sector, which was held by the Xi'an municipal government on June 12.

During the four-month period, many emerging key development projects started construction or were unveiled, such as a new generation national artificial intelligence innovation development pilot zone and the China (Xi'an) Intellectual Property Protection Center.

In the first four months, the electronic information industry of Xi'an High-tech Industries Development Zone (XHTZ) realized a production value of 63 billion yuan, and it is expected to achieve an output value of 230 billion yuan by the end of 2020.

By 2025, XHTZ is striving to build a world-renowned hub for electronic information industrial innovation, with an industrial scale reaching 450 billion yuan.

Also, Xi'an Economic and Technological Development Zone's total industrial output value accounts for one-third of the city. It ranked 11th in terms of a comprehensive index of the 219 national economic development zones in 2019, with its leading industries including automobile manufacturing, high-end equipment manufacturing, new materials and energy, and electronic information.

By 2021, the automotive industry in the zone will gather more than 50 supporting enterprises above a designated size, and the total industrial output value will exceed 100 billion yuan.
