Linking Climatic Resources and Green Tourism Growth Under Climate Change Adaptation Contexts: Evidence from Hue City

This study examines the relationship between climate resources and green tourism growth in Hue City in the context of climate change adaptation. Data were collected from 174 valid tourist questionnaires at Bach Ma, the Hue Imperial Citadel, and the Chuon Lagoon–Thuan An area from April 2024 to March 2025, and analyzed using SPSS version 27. The dataset included 29 climatic variables and five green tourism growth variables. The results show that the scales were reliable and suitable for exploratory factor analysis. The regression model explains 35.3% of the variance in green tourism growth. All five climatic factor groups have positive and statistically significant effects, ranked as follows: wind conditions, rainfall conditions, thermal conditions, extreme weather events, and humidity conditions. The findings highlight the need to integrate climate information, seasonal planning, weather-risk management, and adaptive tourism products into green tourism governance in Hue City.
