Industrial output in Korea's mining and manufacturing industries continued to expand in January.
It marks the fourth straight month of gains.
January's Point-1 percent growth has declined sharply from the previous month.
This is largely because there were fewer work days due to the Lunar New Year holiday.
Statistics Korea says the growth of overall industrial output inched up to the one-percent range in January, suggesting the domestic economy may be recovering.
Spending jumped to a 34-month high of 2.4 percent due to an increase in sales of food and automobiles during the New Year holiday.
