Turkey's industrial output in January boosted 7.9% from the same month last year, the country's statistical authority said on Friday.
Among the three main sub-indices, the mining and quarrying index posted the highest annual increase in the month, with 8.5%, TurkStat said in a statement.
The manufacturing index went up 8.2%, while the electricity, gas, steam, and air conditioning supply index rose 3.8% during the same period.
Industrial production is considered a vital indicator for the economy, as it is seen as a preliminary gauge for GDP growth.
However, on a monthly basis the figure slipped 0.2% in January.
