Manufacturing production rose 8.3% on the year in the January-June period, while mining output was up 5.3%, data adjusted for the number of working days and seasonal factors showed.
On the other hand, output in the energy sector fell 6.4% on the year in the first six months of 2013.
In unadjusted data, first-half industry production increased at a similar annual rate of 6%, again fueled by increased activity in the manufacturing and mining sectors.
For June alone, adjusted industrial output rose 5.7% from the previous month and was up 7.6% compared with the same month of 2012. Unadjusted production increased by 0.7% on the month in June and by 5% on the year.
