A significant part of the world's population goes to different places temporarily or permanently from their place of residence for various reasons. This mobility causes an increase in demand for transportation and tourism enterprises. In addition, the increase in demand in these sectors results in intensification of competition. Increasing competition among enterprises necessitates the determination of enterprise performance and efficiency in order to create a competitive enterprise structure. Throughout history, the world has faced many difficult situations. These difficulties have emerged sometimes as war, sometimes as natural disasters and sometimes as epidemics. On December 1, 2019, the world faced a new infectious disease with the first case of Covid-19 in Wuhan, China. Transportation and tourism sectors are among the sectors most affected by Covid-19 due to the significant restrictions taken by countries. In the study, the activities of enterprises operating in the BIST tourism and transportation sectors were measured with the help of Data Envelope Analysis (DEA) and Tobin q ratio with financial statement data including the periods between the first quarter of 2019 and the third quarter of 2020. When the periods discussed are evaluated, it is not possible to talk about the negative impact of the Covid-19 pandemic on enterprise performance in terms of DEA analysis. According to the Tobin q ratio, it is possible to say that the Covid-19 pandemic has a negative impact on enterprise activities in the transportation and tourism sectors.
