The paper shows an analysis of the global technical efficiency of container terminals of the main ports of Mexico in the period 1982-2010, through Data Envelopment Analysis (DEA). This methodology allows us to measure each decision unit evaluated in relation to other homogeneous units. The aim of the study is to determine the importance of global technical efficiency, pure technical efficiency and scale efficiency in the ports of México. For this purpose, quay length and number of employees are used as input and as output of the number of containers. The results show that the Mexican ports in general have a low technical global efficiency and only the ports showed that technical global efficiency, technical pure efficiency and scale efficiency were Veracruz and Tuxpan in the year 1982, and Manzanillo and Lazaro Cárdenas in the year 2010. For that reason, it requires better operability which means greater mobility of TEUs.
