Abstract: This study investigates the multidimensional impact of international tourism on household livingstandards in Uzbekistan over the period 2000–2023, employing a comprehensive three-equation econometricframework alongside an Autoregressive Distributed Lag (ARDL) bounds testing approach. Three dependentvariables operationalize distinct dimensions of living standards: (i) GDP per capita (GDPPC) as an incomewelfare proxy; (ii) the national poverty headcount rate (POV) as a distributional welfare indicator; and (iii) theHuman Development Index scaled score (HDI) as a multidimensional welfare composite. International tourismis measured by the logarithm of annual tourism receipts in USD million (ln(TOUR)), sourced from the WorldBank World Development Indicators and the United Nations World Tourism Organization. Augmented Dickey-Fuller (ADF) unit root tests confirm that all primary variables are integrated of order one — I(1) — in levels butstationary in first differences, satisfying preconditions for ARDL cointegration analysis. Three OLS regressionmodels — estimated with heteroskedasticity-robust HC3 standard errors and validated through Breusch-Pagan, Shapiro-Wilk, Jarque-Bera, Durbin-Watson, and VIF diagnostic tests — yield theoretically consistentand statistically significant results. Model 1 demonstrates that a 1% increase in tourism receipts is associatedwith a 0.409% increase in GDP per capita (β = 0.409, p
