ABSTRACT
The 2019-2020 COVID pandemic has affected many organisations and companies. One of the most affected sectors is accommodation and food service activities. The aim of this paper is to assess technical efficiency of Czech companies in this sector. The research sample included thousands of enterprises (Group I according to the Statistical Classification of Economic Activities in the European Community - NACE). These enterprises were evaluated for the years 2019 and 2020 in order to track changes in pre-pandemic and pandemic years. The data was exported from the Albertina CZ Gold Edition database. DEA models are used for analysis and comparison. Efficiency scores were calculated based on the CCR (Charnes, Cooper and Rhodes) and BCC (Banker, Charnes, Cooper) models with 6 and 4 inputs and 3 and 2 outputs. The results show that there were already many inefficient companies in the given sector in 2019 and this was also observed for 2020, however, there was a significant reduction in the number of subjects in the database, which may also be due to the impact of the COVID-19 pandemic.
