Using various case studies and empirical analysis, this study establishes how FDI has indeed helped a number of countries tap their potential in tourism regional development and economic adjustment to attract international tourists and achieve sustainable economic growth over a longer period of time and how the important channels of influence are related to the transfer of technology, managerial expertise, and access to global marketing and distribution networks. It not only enhances the competitiveness of individual destinations, but also contributes to broader economic objectives of generating employment, earning foreign exchange, and alleviating poverty. The paper also investigates the varied relationship that is developed between FDI and rural tourism economies. While FDI has been effective in rejuvenating underdeveloped regions, promoting cultural exchange, and diversifying regional economies, it has also raised several concerns about environmental degradation, cultural commodification, and economic inequalities. The study identifies the critical success factors of regional trends in FDI flows through developing and developed economies: political stability, policy frameworks, and availability of skilled human capital. Results have pointed to the need for integrated policy approaches in aligning FDI inflows with regional tourism development goals and ensuring a balanced and inclusive growth path. This research contributes to the literature by elating economic adjustment of FDI and tourism’s regional development, therefore providing useful insights for policymakers, investors, and researchers, who are invited to use these findings to develop policies that enhance the future of regional tourism development and the sector’s economic adjustment. %K Adjustment %K Development %K FDI %K Regional %K Tourism %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=143814
