The Information and Communication Industry (ICT) plays a very important role in the growth of any nation. Therefore, the ITC sector attracts the great attention of the researcher. Despite many breakthroughs and favorable conditions to develop, the Information and Communication Industry (ICT) of Vietnam stands in a very modest position on the world’s ICT map. Therefore, understanding and having an outlook on the performance of companies in this field contribute to the development of the ICT industry in Vietnam. For this reason, the current study is conducted with the main purpose of assessing the performance of 24 Vietnamese ITC companies over past and future periods by applying a hybrid model, including Data Envelopment Analysis (DEA) and Grey model (GM). The author used GM to forecast the future value of inputs and output over period 2018–2022, and then forecasted data is used together with the data of previous years to evaluate the performance of these companies by two models of DEA—Malmquist productivity index (MPI) model and super-SBM-model. This study proposed an approach that can be used by policymakers and decision-makers to develop policies and strategies to sustain the development of the Vietnam ICT industry.
