South Korea's facility investment decreased by four-point-two percent last year from a year earlier, the largest drop in nine years. 

According to Statistics Korea on Thursday, the country's industrial output increased one percent on-year in 2018, posting the narrowest growth since 2000.

Facility investment posted a decrease last year due to a seven-point-one percent contraction in investment in machinery. 

The nation's consumption, however, increased by five-point-five percent last year from a year earlier.
