This research looks at how competitive Thailand's tourism might be in 2035. It checks out things that push growth, like the economy, culture, the environment, and new tech. Thailand's tourism has grown a lot and helped the country's money situation, so the government has put a lot of money into making things better for tourists to stay in the game. But, as more tourists come, things such as money problems, world changes, and health scares could make it hard to keep growing. This study uses special math to guess how many tourists will come by 2035, guessing around 43.8 million. It also sees how different areas are doing by looking at things like airports, roads, cultural events, and how green they are. The results show that what the government does, new tech, and being eco-friendly are important for Thailand to stay ahead in world tourism. By knowing what makes a place competitive, this research gives a way to plan and make smart choices for Thailand's tourism in the long run, making sure it keeps growing while avoiding possible problems.
