The article examines how trade activities impact the efficiency and productivity of Indonesian manufacturing firms from 2008-2015. Two methods, Growth Accounting and Stochastic Frontier Analysis, were used to analyze the data. The study found that imported materials did not affect efficiency but significantly boosted total factor productivity growth. Exporting increased efficiency but decreased total factor productivity growth. There were conflicting results between the two methods, with negative total factor productivity growth in SFA and positive growth in GA. Industries with high imported materials tended to have higher total factor productivity growth in GA but lower in SFA. The Coal and Oil Refinery Industry consistently led in total factor productivity growth among subsectors.
