ABSTRACT The impact of tourism from an economic perspective has been widely analyzed in the empirical literature, with many works that have studied the causal relationship between tourism and economic growth and, to a lesser extent, between tourism and economic development. Both analysis streams are characterized by generally using an analysis approach at the country level or in groups of countries. Contextually, the present work offers an innovative approach by analyzing tourism's relationship with these variables with a regional approach, using NUTS-2 data from Portugal from 2001-2022. In fact, this allows us to know if the contribution of tourism to economic growth and development differs within a country. The instantaneous and Granger causality test results offer significant differences when a regional approach is used instead of analyzing the country as a whole. These results will allow the development of regional tourism policies that enable the benefits of tourism to be channeled.
