The measurement is performed by using the stochastic frontier production function (Farrell, 1957, Coelli, et al., 2005) in the Cobb Douglas form. The purpose of this thesis is to analyse the influence of the use of information technology to business efficiency. The hypotheses were tested with an empirical study against a sample of the top 500 Mexican companies published by Expansion magazine’s annual list, ranked by sales in 2011. The companies included in this sample generate sales between 50 million and 36 billion euro and represent the fields industry, commercial and services.The results show a positive influence on business efficiency by using the information technologies Customer Relationship Management, Business Intelligence and sharing information with customers. This study concluded that these three technologies have a statistically significant level of influence on efficiency in Mexican companies, whereas other ICT tools, such as Intranet, Enterprise Resource Planning, and sharing information with supplier showed no significance in quantitative terms.spadoctoral thesisopen access007.5(72)(043.2)Productivityefficiencyinformation technologystochastic frontier.Tecnología de la información (Biblioteconomía y Documentación)3325 Tecnología de las Telecomunicaciones
