The growth rate is 4.4 percentage points higher than the same period last year, data from the Ministry of Industry and Information Technology showed Friday.

In breakdown, the revenue in manufacturing rose 10.4 percent, while digital revenue in service climbed 8.2 percent.

China has been committed to developing digital technology to transform and upgrade its traditional industries.
