Assessment of performance for Technology-Telecommunication companies in Vietnam using Data Envelopment Analysis (DEA)

The main purpose of this paper is to evaluation of performance measure for Technology-Telecommunication companies in Vietnam industry using Data Development Analysis (DEA). To conduct a valid and reliable evaluation process while applying the companies case in Vietnam, we intergrated the slacks-based measure of super efficiency (super-SBM) and Malmquist index to directly handle the slacks, explore best performer, analyzed the intertemporal efficiency change, which is decomposed into "catch-up" and "frontier-shift" effects and find influential factor in efficiency, technical, productivity change of companies from 2012-2015. The results show that the most TTCs have higher efficiency and contribute more effort to improving technical change during 2012-2015. By comparing the efficiency of TTCs, this research provides an approach of decision-making information for manager as well as contributes to orientation for the development of technology and telecommunication.
