The modern world is facing chaos of different connected issues. Achieving sustainability in the tourism industry for poverty reduction is one of them, having limited guidance for stakeholders. Thus, following SDG-3 guidelines for good well-being via tourism development could contribute to SDG-1 for no poverty. This roadmap needs scientific validation. Therefore, this research aims to determine how much of an overall impact tourism has on alleviating poverty and what factors account for the wide range of estimates of that impact. Using data from 2002 to 2020 and the ARDL model with eight variables, including (a) currency supply, (b) GDP per capita, and (c) tourism earnings higher GDP area, the current emphasis is on reducing the likelihood of any negative impacts this business may have on tourism. Lower Gross Domestic Product (GDP) regions, higher profits per capita from tourism, and reduced poverty all have a role. With a 1% significance threshold, the observed data becomes more convincing. Last, the results show that the Laotian government intends for tourism to contribute to long-term environmentally responsible financial development. In addition, the study's empirical results corroborated the conclusion that policymakers should encourage the successful expansion of the tourist industry.
