We know that the economics of science is about achieving optimal revenue using scarce resources. Similarly, the problem that the world\\\'s economies are trying to address is how to achieve an optimal economic share of limited tourism resources. Given that global studies and statistics indicate that exchange rate is considered to be one of the most important factors in developing countries, it has been termed exchange rate as a solid building block of development. In this study, panel data were collected from 14 selected Southwest Asian developing countries during the 2011-2016 annual period, and the model was applied and estimated using the system generalized momentum method. The model estimation results show that only the hypothesis of this study which shows the positive and significant effect of good banner index on the amount of revenue from tourism industry has been confirmed and its effect has been positive and significant and also the exchange rate variables. Income and business openness have also had a significant positive impact on the tourism industry\\\'s revenue.
