BEIJING - China's industrial value-added output rose 9.3 percent year-on-year in April, the National Bureau of Statistics said Monday.

The growth rate, flat from the same period last year, accelerated from the 8.9-percent growth seen in March, the NBS said in a statement on its website.

Value-added industrial output measures the final output value of industrial production, or the value of gross industrial output minus intermediate input, such as raw materials and labor costs.

In the first four months, total industrial value-added output increased 9.4 percent year-on-year, compared with a 9.5-percent growth rate registered for the first quarter of the year.

The industrial sector's output for April added 0.87 percent in comparison to March, the NBS data showed.
