Container terminal production is both an important and complicated element in the contemporary global economy. Amongst other methods, the efficiency of container port or terminal production can potentially be analyzed by Data Envelopment Analysis (DEA). This paper aims to evaluate the efficiencies of the Yangon’s ports using the two alternative techniques. This paper provides a preliminary analysis of Yangon’s port sector for the period (1998-99 to 2007) using DEA in order to asses the impact of transformation. The results are therefore important in terms of the extent to which Yangon’s ports will be capable of competing effectively in the port industry. The scale of merger and takeover activity across the port industry has been extensive in recent years and this can be expected to increase as new opportunities for market penetration and consolidation emerge in the new-private ports sector.
