persistently high productivity levels and continuous efficiency improvement. For UMIEs, EE decreased moderately from 121.1 to 110.4, and LP rose from 0.768 to 1.305. Although the overall trajectory is less steep than that of HIEs, UMIEs show a gradual upward movement, indicating steady gains in productivity alongside moderate efficiency improvement. group recorded the largest relative improvement in productivity among the three, but starting from a lower initial base. The LMIE trajectory moves substantially upward and to the left, reflecting rapid growth in labor productivity concurrent with an increase in EE. productivity, though from different starting points and at varying speeds.
